When being the bright spark isn’t such a good thing

“Bright”, “Brilliant”, “Sparkling” …all terms used more often than not to describe positive attributes. But in a recent visit to a Dialight customer, we ran across a situation where a “Bright Spark” was the cause of a very negative situation indeed.

PPL Generation Upgrades to Dialight’s Vigilant® LED High Intensity Strobe at Martins Creek Power Plant

With Fuellgraf Chimney & Tower’s recommendation, Dialight’s LED Obstruction lights retrofit PA Facility

As part of its ongoing commitment to improving operational efficiency and reducing environmental impact, PPL Generation continually strives to reduce costs and lower internal energy consumption by implementing high-efficiency, modern technologies throughout its facilities.

At its 1,700-megawatt Martins Creek Power Plant north of Easton, Pa., the company recently replaced the antiquated Xenon obstruction lighting system on the facility’s two exhaust stacks with state-of-the-art 270,000 candela LED High-Intensity Strobe systems from Dialight, the industry leader in LED obstruction lighting technology. The retrofit will reduce PPL Generation’s maintenance and energy costs.

The Challenge
Constructed in 1974, the Martins Creek facility consists of two oil/natural gas-fired units with a generation capacity of 850 megawatts each. Twin 600-foot ventilation stacks tower over the facility and its surrounding neighbors, each signaled by the requisite FAA obstruction lighting system.

The existing systems, comprised of two sets of three Xenon strobes at positioned 296 feet and 586 feet, had been in place more than 30 years, since the plant first came online. Annual bulb replacements were becoming a significant financial drain in both supply and manpower costs. In 2010 alone, the Martins Creek plant had to replace 10 out of 12 lamps. The year before, the plant replaced all 12 lamps.

The Solution
Recognizing the need to upgrade, PPL worked with its electrical and lighting contractor, Fuellgraf Chimney & Tower, to specify a new high-efficiency LED system.

Based on the highly successful installation of Dialight’s high-efficiency LEDs at the adjacent Lower Mount Bethel Energy power plant, Fuellgraf replaced both of the outdated Xenon systems at the Martins Creek plant with Dialight’s L864/L865 dual LED obstruction fixtures. Backed by a 5 year full performance warranty and highly durable shock and vibration resistance, the Dialight system had already proven to deliver reliable, long-lasting performance and exceptional energy savings.

Considering the energy efficiency and reduced maintenance cost of the LEDs, it adds up to substantial savings, making it an easy decision for our customers when it comes to upgrading their outdated xenon systems. - Joe Geiger FC&T

The Results
Outfitted with custom-built controllers and neighborhood-friendly optics to reduce ground scatter, the new Dialight units were installed in about a week per stack by Fuellgraf’s team.

Consuming just 250W during the day and only 10W at night, compared to the Xenon’s 500W daytime operation and 300W at night, the Dialight system uses significantly less electricity than the Xenon system. But, the most immediate direct benefit of the retrofit will be the dramatic reduction in reoccurring maintenance costs. With Dialight’s proven product longevity that reduces system maintenance, PPL Generation will continue to save for years to come.

It is Fuellgraf’s goal to always provide the best system available on the market for its customers. Through our partnership with Dialight we are able to provide the best technology, the greatest support, reduced maintenance cost, lower energy consumption, the most experienced installation company, excellent safety record, and a wide range of value added products .

Case Study: LED Lighting to Deliver Payback in Just Over Two Years for Global Packaging Company

Installation Snapshot
• Replacement of 340 x 400W MV with 150W LED high bays
• Over 60% reduction in energy needs
• 460 tonnes annual reduction in CO2 emissions
• Expensive maintenance eliminated
• Improved safety and productivity
• Payback just over two years

As a leading consumer packaging company with 83 manufacturing sites across the globe, Rexam makes the packaging for many of the world’s favourite brands, striving to produce it as efficiently and sustainably as possible. Producing 4.5 million cans a day for the UK and Northern Europe at its beverage canning plant at Milton Keynes UK, the company took the decision to review its lighting at this facility in order to reduce energy consumption.

The Challenge

The Milton Keynes production line and warehouse are in constant use and the lighting runs 24/7. The company had previously had issues in two other plants with mercury vapour lamps, so it had taken a decision to enclose them all or change them out altogether. It therefore made sense to look at a new lighting solution that would save energy as well as meeting safety standards.

With 340 x 400W mercury vapour high bays throughout the facility, energy costs were high, but maintenance was also a big consideration. At eight metres mounting height, those fittings above the production line had a hard task to produce enough light because of build-up of film from oil vapours in the atmosphere. The print area is also full of conveyors and gantries which further filter the light as well as making the light fittings very hard to access. The mercury vapour high bay lamps were averaging a 2-3 year lifespan and being replaced when they failed or looked ready to fail at a rate of around 40 a year. This often involved bringing in specialist hired riggers at a cost of £750/day.

The Solution

Electrical Supervisor, Stuart Macey looked at six alternative lighting solutions from a variety of manufacturers, trying out samples over a three month test period, before choosing Dialight’s DuroSite® Series LED High Bays on the combined basis of price and performance. Rather than rewire the plant, he replaced the 400W mercury vapours one-for-one with 150W LED high bays throughout the production and warehouse areas.

The Result

Stuart calculates that his lighting energy needs for the high bays have reduced from 1,100kWh to 433kWh per year, a saving of £43,000 annually at a rate of £0.06/kWh, and estimates a payback period of a little over two years when comparing this investment in LED technology with the alternative solution of installing open rated lamps to meet the new corporate safety standards. He also notes that further savings can be counted from the reduced maintenance burden thanks to Dialight’s continuous performance warranty.

To Stuart’s surprise the warehouse is where the LED high bays have brought unexpected benefit. Mounted at 11-15 metres in a palletised area with no aisles, they’ve been a major success. He comments: “The lighting used to be poor, but now operators find the quality of light restful and good for the eyes – more like daylight. As this area is our last chance to check product quality, the lighting is important to us. We’ve had the LEDs in place for eighteen months with no failures, so our high bay lighting is no longer a Health & Safety issue and this installation is now regarded as a best practice example for all our plants.”

Case Study: Waste and recycling facility cuts lighting energy needs by 68% using LEDS

Installation Snapshot
• 50% failure rate in existing metal halide fittings
• (24) 400W metal halides replaced by (24) 148W LED high bays
• 68% cut in energy needs
• Lux levels increased x3
• 1.3 year payback
• 33.1 tonnes CO2 reduction over lifetime of lamps

Hazardous recycling shed is now safer, cleaner, brighter for workers and more sustainable.

Oxigen Environmental manages the waste streams of 100,000 domestic, commercial and industrial customers in Ireland. The company prides itself on utilising sustainable solutions to maximise resource efficiency through recycling and energy regeneration.

Recognising that the existing lighting in the recycling shed was inadequate and a drain on resources, the company set out to find a more efficient lighting technology.

Visibility in the recycling shed was very poor, as no natural light entered the building and the metal halides installed could not provide a good level of light output. The metal halide bulbs were prone to rapid deterioration and discolouring, and out of the 24 fixtures installed 50% had failed. Debris from the machinery added to the harsh and dusty environment of the shed, reducing visibility further as the halides accumulated dirt.

Maintenance became a big issue, as the positioning of the heavy machinery and height of the shed meant that the metal halides were difficult to access and the failed bulbs could not be replaced easily. The combined effect caused the workers to rely on the headlamps from the loaders.

Operating 24/6, the metal halide fittings proved to be very costly for Oxigen. Consuming 400W per unit, this resulted in an annual power usage of 85,363kWh which was not only a huge cost in electricity, but also a huge output in CO2.

Working with Commercial Energy Solutions, a company specialising in energy reduction usage, the halides were replaced one-for-one with Dialight’s high efficiency LED High Bays. Consuming only 148W, the units reduced the energy consumption dramatically, saving 68% in energy costs annually. The LED fixtures have instant on/off capability allowing the lights to be used when required, saving unnecessary electricity consumption and preventing irritation as the lights do not flicker on re-strike.

The shed is now three times brighter with lux levels at 140+ and as a result the workers can see clearly without relying on the headlamps of the loaders. This has improved health and safety significantly and the productivity in the shed has increased.

Maintenance has also been eliminated within the shed, as the LED units are sealed, with a life expectancy of 100,000 hours and an unconditional 5-year warranty, so no bulb replacements are required. As Dialight’s LED fittings are shock and vibration resistant, they are perfect for the hazardous environment of the shed.

With a payback period of only 1.3 years, the LED units have proved to be the best lighting solution for Oxigen. The units have also reduced carbon emissions by 68% and Oxigen can expect energy cost savings of £91,051 and 33.1 tonnes reduction of CO2 emissions over the life of the LED fittings.

“The CES team worked with us through each stage of the project, from proposal right through to completion. They delivered a high quality, energy efficient lighting solution that delivers tangible savings whilst achieving greatly improved light quality and levels.” Aidan Doyle, Director of Operations, Oxigen.

Small Space, Big Responsibility

Charged with complete municipal operations for the City of London’s central business district, the City of London Corporation’s one-square-mile footprint may seem small, but there are some big shoes to fill. The Corporation is the sole public works provider for the zone, providing for all utilities, public safety, street maintenance and winter maintenance, refuse collection and complete facilities management for city-owned properties. The majority of these operations are run out of the Corporation’s Walbrook Wharf facility. Originally constructed in 1960, this bustling four-level parking and vehicle maintenance hub, houses the Corporation’s day to day operations.

For the last 50 years, the facility had relied on the original lighting fixtures put in place at the time of construction. Mostly five- and six-foot fluorescents with a few 400W high-pressure sodium units, the fixtures had not only become obsolete but also a significant drain on resources—both in terms of maintenance time and costs and energy consumption. The 134W fluorescent and 275W SON fittings were hardly energy efficient and required frequent replacement, as they were often hit by truck drivers. Because of the inefficient warm-up time required, especially for the HPS fixtures, the lights in the facility were often left on 24/7.

The fixtures were also dirt collectors, which reduced visibility as diesel exhaust soot and dust from the constant traffic built up over time. To ensure safety and avoid frequent interruption of traffic flow, the Corporation underwent a complete facility-wide fixture cleaning and relamp project every 18 months—a costly and time-consuming process.

Dialight Upgrade Delivers Modern Efficiency

Faced with a resource-intensive maintenance treadmill, the Corporation was determined to upgrade to a more efficient and environmentally friendly lighting solution, partly to save energy and money, but also to meet the Corporation’s Energy Reduction Action Plan (ERAP) and avoid being taxed on its carbon footprint through the UK’s Carbon Reduction Commitment (CRC) program.

As part of its commitment to achieving the ERAP and CRC energy and carbon reduction targets, the facility aimed to reduce electricity consumption by 15 percent by 2015. Realizing the high impact lighting had on its energy use, the facility immediately honed in on this area to offer the largest and quickest potential savings.

After learning about the success of Dialight’s fixtures at London’s ExCeL Centre, the Corporation quickly arranged for a three-month trial of Dialight’s LED Low Bay fixtures.

“The Dialight product met all of the criteria we were looking for in terms of substantial energy reduction, lower maintenance and durability,” said the project team based at Walbrook Wharf. “Once we spoke with the facilities manager at the internationally renowned ExCeL Centre, it was a no-brainer for us to proceed with the upgrade to Dialight LEDs throughout the facility.”

Less is More: Better Lighting with Fewer Fixtures, Less Energy

The facility initially installed 25 80W LED Low Bay fittings for a 1-for-2 replacement of its existing fluorescent fixtures on the 2nd floor parking area. The Corporation immediately realized a dramatic improvement in visibility, thanks to the superior color rendering and specialized optics design of the low-bay products, and a real-time energy savings of 70 percent, all while increasing the lux level, even with exactly half the number of fixtures in place.

In phase two, the depot installed 19 Low Bay and two High Bay units on the ramps between the 1st and 2nd floors, and another 17 Low Bay fittings on the 1st floor parking level. By reducing the fixture count and electricity required to drive the system, the Corporation was able to cut the power demand from 16 amps to 5 amps per floor.

An additional 12 High Bay units are also now in place in the salt storage area, with plans to upgrade the vehicles workshop area with an additional 52 Dialight Low Bays in the very near future, bringing the total Dialight LED fixture count at Walbrook Wharf to 127 units.

Adding to the significant reduction in energy use, each parking deck has been equipped with occupancy sensors that detect motion and activate the fixtures only as needed. If no motion is detected, the lights automatically turn off after about 15 minutes. Requiring zero warm-up upon restrike, the Dialight LEDs’ instant-on capability has enabled this automatic on-off feature to cut “on time” by about 50 percent, saving a tremendous amount of energy compared to the previous 24/7 operation and significantly extending the life of the fixtures themselves.

“The Dialight units are rated for a minimum 60,000-hour life span, which equates to almost seven years of continuous operation without a single bulb change required,” said the team. “Since the occupancy sensors reduce operational time, they are likely to last much longer than their given life expectancy.”

So far, the upgrade to LED has reduced annual operating time of the fittings by 2,190 hours, saving more than 121,000 kWh per year, which equates to more than 8 percent of the facility’s entire energy consumption. Between the reduced energy use and maintenance demands, the Corporation expects to realize an annual savings of more than £15,000.

“And, with Dialight’s five-year warranty, we’re confident we won’t have to touch these fixtures, other than for an occasional washing, for many years,” says the team, noting the fixtures are IP66 rated, which makes periodic wash-down safe and easy. “We were also quite impressed with the fact that each fixture took only about five minutes to change out. Each came pre-wired with a simple hook and plug mounting system that made for a very easy and efficient retrofit.”

Dialight’s Durability, Sustainability Make for a Long-Term Solution

Beyond the energy and maintenance advantages, the robust solid-state Dialight fixtures also offer superior durability and resistance to shock and vibration, which are critical factors in the parking facility where heavy truck traffic can damage less resilient filament-based lighting fixtures. Furthermore, because the LED units emit much less heat compared to conventional fluorescent or HPS units, there’s a much lower risk of fire due to overheating, especially as fine particles inevitably accumulate on the fixtures.

With a payback period of less than three years, the Walbrook Wharf Dialight LED conversion has provided an energy-efficient lighting solution that puts the Corporation well under its ERAP and CRC energy- and carbon-reduction goals long before the 2015 deadline. As the entity continues to look at ways to optimize operations and minimize its environmental footprint throughout all its facilities, Walbrook Wharf serves as a showcase for the potential energy, maintenance and cost savings made possible by Dialight LED lighting solutions.

Dialight Launches First FAA-Certified L-864 Red Beacon with Integral IR LEDs

Latest Addition to Dialight’s Industry Leading Vigilant® Series LED Obstruction Lighting Portfolio Improves Visibility and Safety for Aviation Near Military Bases

FARMINGDALE, N.J. (May 10th, 2012) -- Dialight (LSE: DIA.L), the market leader in LED obstruction lighting, today announced the availability of its new Vigilant L-864 Infrared (IR) LED-based Medium Intensity Red Beacon, the first product of its kind incorporating both red and IR LEDs in a single unit.  The product has been FAA certified to 150/5345-43F. The IR integration ensures better visibility for aircraft pilots using Night Vision Goggles (NVGs) and Aviator’s Night Vision Imaging Systems (ANVIS) for improved safety near military bases and airfield perimeters within the most energy-efficient L-864 beacon in the industry.

The new IR beacon is the newest innovation in Dialight’s decade-long history of delivering the most energy-efficient LED obstruction lighting solutions for towers, buildings, smokestacks and more. The company continues to expand its integrated IR product line; the IR L-864 beacon now joins Dialight’s IR L-810 side marker light, the first-ever LED obstruction light certified to 150/5345-43F with integral IR LEDs.

“Dialight leads the LED obstruction lighting market with superior technology and innovation that is shaping the future of aviation navigation,” said Roy Burton, Dialight Group Chief Executive. “This latest product delivers exceptional energy efficiency, virtually zero maintenance and built-in IR technology that eliminates the need for bolt-on systems that add to both wind resistance and maintenance costs.”

NVGs and ANVIS typically employ Class A, B and C filters that can reduce visibility of typical LED light sources. Unlike other beacon systems that require separate IR units, the Vigilant IR beacon incorporates night-vision-friendly IR LEDs and red LEDs in the same unit, leveraging the same compact design of Dialight’s standard L-864 to produce the smallest and lightest-weight flash head on the market. This smaller footprint significantly reduces wind load compared to incandescent L-864 beacons and makes for much easier installation. The multi-patented system also features community-friendly optics for minimum ground scatter. The system offers a peak IR spectral intensity at 860 nanometers.

A new hinged lid design enables easy access to terminal block wiring for installation and power supply maintenance. Control circuitry may be located at the base of the tower for better protection against lighting, while the IP66 certified beacon design is factory sealed for durability and rugged performance in the harshest conditions, even at operating temperatures ranging from -40°F to 131°F (-40°C to +55°C). With a 10-year LED life expectancy, backed by Dialight’s 5-year full-performance warranty, the Vigilant IR L-864 beacon dramatically reduces maintenance costs, virtually eliminating expensive tower climbs, unplanned site visits and the risk of non-compliance fines due to burned-out bulbs.

In addition to exceptional maintenance savings, the unit is also extremely energy efficient to save on electricity costs, drawing only a small fraction of the power required by a typical 1400W incandescent system. Rated at just 40W, the Dialight IR L-864 operates at 6.7W on a normal 16.7% duty cycle of 20 half-second flashes per minute. The typical incandescent draws more than 230W on the same cycle. This low-power consumption also provides for extremely low RF interference, making it ideal for lighting “hot” AM towers with no disruption in signal transmission.

The Vigilant IR L-864 can even be adapted to existing incandescent beacons for a future-proof system. Should the red beacon fail on a dual incandescent, the IR L-864 can be synchronized with the existing white incandescent, to get the maximum possible useful life out of the existing technology.

In addition to FAA certification, the IR L-864 is also compliant with the ICAO Annex 14 and Aerodromes Design Manual European specification and Transport Canada’s Canadian Aviation Regulation CAR 621.19.

Dialight LED Low Bay Fixtures Provide a Clever Lighting Solution for Denver’s Fox31 Parking Garage

(Before & After LED Installation)

Installation Snapshot
• Retrofit installation
• (147) 80W LED Low Bays
• Replaced 175W metal halide
• Delivered light: ~ 20 Footcandles
• Payback: 3 years
• Received over $10,000 in energy efficiency rebates

Plagued by seemingly never-ending light maintenance in its two-deck parking garage, Denver’s Fox31 television news station has put an end to the incessant bulb and fixture changes and saved thousands of dollars in the process by converting to new high-efficiency DuroSite® LED Low Bay luminaires from Dialight Corporation. The retrofit slashed energy use by more than half and dramatically improved visibility inside the garage, while earning the station more than $10,000 in energy-efficiency rebates.

Watch Your Head!

Like most multi-level enclosed parking garages, the Fox31 TV news station facility in Denver seemed a dark and cavernous space, made further uninviting by the low clearance (just 8-10 feet) between each deck. The facility’s 15-year-old metal halide lighting fixtures provided inconsistent illumination and low light levels, at best—as little as 1 footcandle in some areas. Not only were the fixtures themselves antiquated and inadequate for this kind of low-bay application, they were also inefficient, consuming 175W per unit (up to 208W including the ballast.

Maintenance was a never-ending chore for Fox31 due to the metal halide’s inherently short lifespan and the high-profile news vans which seemed to impact the fixtures on a regular basis. The station was spending far too much time, about once per year, and money in replacing damaged lights and relamping all 147 fixtures. Considering that many were difficult to access, especially those lighting the steep ramps between the decks, the Fox station was eager to find a more modern, economical and energy-efficient solution to shed some much-needed light on its “den.”

Durability, Efficiency and Savings Courtesy of Dialight

At the recommendation of Denver-based LED Supply Co., the station replaced all 147 metal halides with new LED DuroSite Low Bay Fixtures from Dialight, the world leader in industrial LED lighting solutions. Offering a ruggedized, low-profile design at less than 9” in overall depth off the ceiling, the DuroSite Low Bays promised to put an end to the news vans knocking out the lights, while delivering a significant improvement in visibility at a much lower operating cost.

“Low profile was a big factor in the decision to go with the Dialight fixtures,” said Brian Stern, president and CEO of LED Supply. “The Dialight units are a full six-inches shallower than the existing metal halides, which put them safely out of range for the satellite-topped news trucks.”

Since the new Dialight fixtures were fully compatibility with the existing wiring and mounting brackets, changeout of all 147 lights was quick and easy, completed in just four days.

Consuming just 80W, the new Dialight Low Bays immediately reduced overall lighting electricity consumption by nearly 55 percent, while delivering up to 20 footcandles of crisp, clear white light with a CRI of 70, compared to the low light quality of the metal halides.

“The improved visibility is quite dramatic, like night and day almost,” Stern said. “Since the optics in the Dialight units are optimized for low-bay applications, they efficiently direct the light exactly where it’s needed and better illuminate the area while minimizing glare, which makes for a safer environment for drivers in the facility.”

Years of Dependability and Ongoing Savings

Each DuroSite fixture has an expected fixture life of at least 60,000 continuous hours of worry-free and maintenance-free performance. This means the station could easily go more than a decade without ever having to change a light bulb, with half that time backed by Dialight’s five-year, full-performance warranty. And, because the Dialight units are especially resistant to shock and vibration—both big issues in multi-level parking garages—the new lights offer a long-life durability that renders the old metal halides virtually obsolete.

“This was one of our best facilities investments to date,” says David Harpe, vice president of Technology for KDVR and KWGN. “We are a 24-hour facility with a staff of over two hundred employees. There are relatively few opportunities for cost savings with a facility like this. Although we’d been looking at LED lighting for quite a while, we had a hard time finding a fixture with the performance and ROI numbers we needed. With the team from LED Supply Co., we were able to come up with a Dialight-based solution that ended up being a 'no brainer' from a numbers perspective. In addition to the cost savings and short ROI on these lights, we’ve been getting great comments from our staff about the quality of light we now have in our garage areas. We’re really pleased with our investment.”

As a result of the substantial energy reduction, the Dialight retrofit qualified Fox31 for more than $10,000 in energy efficiency rebates—equaling just over $70.00 per fixture—through Xcel Energy and the City of Denver that helped to significantly offset the cost of the project. Between the rebate, the dramatic energy savings and the money saved by eliminating maintenance, Fox31 expects a payback period of just over 3 years—a very healthy return on investment for products that will last nearly four times as long.

Case Study: British Fruit Importer Overcomes Rising Energy Costs with Dialight LED Lighting

Installation Snapshot:

• New installation
• (134) 150W LED High Bays w/ occ sensors
• (16) 80W LED Low Bays w/ occ sensors
• Delivered light: ~300 lux
• Payback: 2 years
• 19% return from UK’s Enhanced Capital Allowance (ECA) scheme

One of the largest importers of fresh fruit in the United Kingdom, MMD Shipping’s inbound facility at the City of Portsmouth handles roughly 60 percent of all bananas brought into the UK. With a dozen ships that traverse the Atlantic hauling fruit “across The Pond” from the Caribbean, MMD operates a 12-warehouse facility that receives and distributes all varieties of fresh fruit to the British market.

Already coping with a nearly 20 percent increase in energy rates over the past year, the company was facing an additional 10-15 percent year-over-year increase down the road. In an effort to overcome the rising cost of electricity and improve overall operational efficiency, MMD has recently begun to install Dialight’s high-efficiency LED lighting fixtures at both its new and existing facilities. Not only has the effort paid off by cutting energy consumption and cost with an expected ROI of two years but it has also dramatically improved lighting efficacy and safety while reducing maintenance demands and expenses throughout the company.

New Facility Demands New Approach to Lighting

With construction of its new 3,000 square meter (32,000 square foot) Portsmouth cold storage facility underway, MMD began looking at a variety of lighting solutions. Lighting needs alone accounted for up to 15 percent of the company’s total electrical consumption, and rates had already jumped considerably over the past year. Looking to minimize consumption and costs, the company compared Dialight LEDs against some other LED products, as well as induction and fluorescent options, for its new chill store.

Working with Elite Renewables, a Dialight authorized distributor and installation contractor, a trial of the Dialight product ultimately demonstrated superior light output with the High Bay fixtures delivering up to 320 lux on the floor, even at a ceiling mounting height of 12 meters (nearly 40 feet). MMD had found its high-efficiency lighting solution for the new cold storage facility. Elite Renewables then went to work providing complete lighting schematics with layouts and measurements to optimize light efficacy.

“The improvement in on-the-ground lux level made possible with the Dialight High Bays was truly impressive,” said Adrian Corthine of Elite Renewables. “In some areas, the 320 lux was nearly five times what the typical metal halide or high-pressure fitting could provide and with a much greater operational efficiency.”

Dialight Delivers Dramatic Savings

The company installed 134 Dialight 150W High Bays in the cold storage area proper, with an additional 16 Low Bay units in the indoor and outdoor loading bay areas. Not only do the fixtures deliver even illumination with clear, crisp white lighting, but due to the LED’s superior performance in cold applications, the fixtures in the chill store actually deliver more than the advertised lumen output, thanks to the ambient temperature of 5°C. And, with the Dialight LED’s exceptionally low heat output, the entire cold storage locker runs more efficiently with less refrigeration demand to maintain optimum temperature.

Finally, each fixture is also linked to occupancy sensors to illuminate the area only when needed. Instead of the 24/7 burn time common with other conventional lighting solutions, the fixtures are only on about 30 percent of the time. This feature alone delivers dramatic energy savings compared to typical metal halide or high-pressure sodium fixtures and significantly extends the life span of the fixture itself well beyond its warranted five-year period.

“We have been extremely pleased with the energy savings and reduced operating cost we’ve seen with the new Dialight fixtures in the cold storage facility,” said Tim Schofield, Financial Controller with MMD. “In fact, we’ve been so impressed with the performance and warranty that we’ve begun retrofitting nearly all of our other facilities to Dialight LEDs to improve efficiency, lighting efficacy and safety throughout our operations.”

Outstanding Results Drive Corporate-Wide Rollout

With the new cold storage facility now complete, MMD has since purchased an additional 440 Dialight fixtures for a one-to-one replacement of existing 400W metal halide fixtures at 11 other warehouse buildings. At one banana storage facility, the retrofit has earned rave reviews from the employees who immediately noticed a vast improvement over the previous lighting conditions. The reduced heat output of the LEDs has also helped improve temperature maintenance in the banana facility. The chillers no longer have to work so hard during warmer weather to keep the temperature down and the product itself benefits from optimum, even temperatures throughout.

Furthermore, the long-life performance of the Dialight LEDs will significantly reduce MMD’s lighting maintenance needs, which were once a costly and cumbersome exercise. Now, rather than halting production to bring in a scissor lift and change bulbs every few months, the facility can enjoy years of reliable, steady light output with virtually zero maintenance.

Tax Incentives Sweeten the Deal

Supplementing the energy and maintenance savings, MMD has also been able to take advantage of a nearly 20 percent tax break from the British government as part of the UK’s Enhanced Capital Allowance (ECA) scheme. The program allows companies that invest in energy-efficient equipment and machinery to write off the entire expense in the year in which the investment is made, rather than amortize the cost over several years. Similar programs are also available in the U.S. for Designlights™ Consortium qualified products, such as the Dialight High Bay fixtures.

“I don’t understand why everyone doesn’t go LED,” Schofield quipped. “Between the energy and maintenance savings, and the tax incentives, the switch to LED fittings was a no brainer.”

ExCeL London Expands LED Lighting Retrofit Ahead of London 2012 Olympics with New Dialight Fixtures

Award-Winning International Exhibition & Convention Centre Upgrades Exterior Lighting to Meet the Olympic Light Level Requirements with New Hi-Efficiency Dialight High Bays for Improved Visibility, Security in Loading Dock, Parking Areas

Newmarket, UK (April 3, 2012) – In preparation to host the London 2012 Olympic Games, the award-winning ExCeL London International Exhibition & Convention Centre has expanded its efforts to convert the facility to greener, more energy-efficient LED lighting, replacing 35 existing 400W high-pressure sodium (HPS) fixtures with Dialight’s new 150W 14,000 lumen High Bay LEDs to better illuminate the north side exterior of the massive structure in the loading dock and traffic marshaling areas.

The latest change-out project builds upon the 2010 retrofit of 194 400W high-pressure sodium units with 150W Dialight High Bays throughout the building’s one-half-mile-long Central Boulevard area. That conversion, performed by Dialight authorized distributor Elite Renewables, reduced energy consumption by 70 percent in the main thoroughfare and enabled the 100,000 square meter ExCeL London, one of the greenest and most energy-efficient of its kind in the world, to double the on-floor illumination (from 100 to 220 lux) and achieve three-times the energy efficacy (4.2 W/m2 compared to 12.32 W/m2 with the previous HPS units).

The new exterior installation enhances illumination and visual clarity for improved traffic management and security in the area where event-related equipment staging, loading and unloading takes place, as well as at the entrance/exit to the facility’s massive underground parking areas. The previous HPS fixtures were plagued by extended warm-up periods and were on a manual switch, which meant they were often accidentally left on when not needed because personnel simply forgot to shut them off, wasting valuable energy and money.

Elite Renewables installed each new Dialight fixture with a photocell for automatic dusk-to-dawn operation and the instant-on capability adds safety and security. In the event of a power failure, the Dialight LEDs will immediately restrike at full output the second the backup generator kicks on, virtually eliminating this safety and security risk at the high-profile event centre. The new units are also maintenance free, backed by Dialight’s 5-year full-performance warranty.

“We’ve been extremely impressed by the outstanding quality of light and energy savings we’ve achieved from our previous Dialight installations throughout the Centre. It’s been a significant improvement to the visitor experience that has kept our world-class facility in high demand for high-profile events,” said ExCeL’s Building Services Manager Chris Barnes. “Based on our experience with the Dialight product, it was the natural choice to take advantage of the Dialight technology to improve our exterior lighting as well.”

ExCeL London will play host to 7 Olympic and 6 Paralympic events when the Games of the Olympiad kick off July 27, including the boxing, wrestling, judo, tae kwon do, table tennis, boccia, weight lifting and power lifting, fencing, wheelchair fencing and sitting volleyball competitions.

“It’s been a distinct pleasure to work with the ExCeL team to help this incredible facility achieve its objectives for energy efficient lighting and become a showcase of sustainable design and operations,” said Roy Burton, Dialight’s Group Chief Executive. “With 200+ Dialight LED fixtures already installed, we look forward to working on future retrofit upgrades throughout the venue and surrounding campus areas.”
