Dialight’s 8W SafeSite® RTO LED Area Light Now Delivers 100 Lumens Per Watt for Hazardous Locations

8W Fixture Now Up to 90% More Efficient Than Incandescent or CFL Jelly Jar Light; AC and DC Versions Ideal for Solar, Low-Power Applications in Oil & Gas or Chemical Classified Environments

Farmingdale, NJ (November 28th, 2012) – Dialight (LSE: DIA.L), the innovative global leader in LED lighting technology, today introduced its new ultra-energy efficient 100 lumens per watt SafeSite® RTO LED Area Light. Consuming just 8 Watts, the new RTO Area Light is the most energy efficient product of its kind and the only one certified for use in Class I Div 2 environments, as well as Class II Div1 and Class II Div 2 (Groups D, E, F) applications.

With its 12-48V DC input capability, the RTO Area Light is ideal for solar and other low-power needs, including battery-backup operation, unmanned off-shore oil platforms and other hazardous location applications. The RTO Area Light models are also available for 100-277V AC use. The fixture is also UL 844/1598, UL50/E and IP66 certified for wet-locations.

Designed as a complete fixture retrofit for up to 75W conventional incandescent or compact fluorescent jellyjar fixtures, both the area lights are L70 rated for >100,000 hours at 25°C and backed by Dialight’s 5-year full-performance warranty to virtually eliminate lighting maintenance for continuous, reliable use. The fixture’s instant-on capability allows the lights to be switched off when not needed, eliminating the energy wasted from keeping conventional lights burning 24/7 to avoid the restrike delay.

“Dialight’s expanding portfolio of hazardous location products has earned us an international reputation for cutting-edge product design that meets our customers’ ever-changing needs,” said Roy Burton, Dialight’s Group Chief Executive. “The RTO Area Light fixture offers the outstanding long-life reliability and performance our customers have come to expect, with a low-wattage unit that cuts both energy and maintenance costs.”

Factory sealed inside a ruggedized housing for superior durability and weather resistance, the Downlight is suitable for both interior and exterior use, even in the most extreme environments with a broad operating temperature range of -40°F to +133°F.

The SafeSite Area Light is compatible with a wide range of mounting options, including pendant mount with or without junction box and ceiling mount with or without junction box. Flush-mount and junction box wall mounting accessory kits are also available.

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.”
