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.”
