Dublin Airport Authority retrofits Ellydees Wattbeater lamps
They have replaced old technology 150W linear tungsten halogen lamps with 7W LED , delivering over 95% energy saving and slashing maintenance costs.
About the Project...
Old technology linear tungsten halogen lamps were used on air bridges, a moveable walking ramp that connects planes to the airport terminal. Halogens are highly inefficient bulbs, with 95% of the energy lost in heat and only 5% used to produce light. They are prone to shatter due to vibration which is not ideal for use on an airbridge which is moved constantly. For health and safety reasons the lights on the air bridge burn 24/7 so the energy saved by swapping to LED technology is huge.
LED lamp has a 30,000 hour life with a 5 year warranty and retrofits easily into the existing halogen lights; you don’t even need an electrician! DAA estimate that they will save €11K per annum based upon an energy saving per lamp of (143) watts with electricity KWh cost of €0.10c.
Mr Damien Garry, Systems Manager in Asset Care Department at Dublin Airport Authority says ‘We were getting frustrated with the fact that in our 19 No. new Airbridges the halogen l amps were failing every few weeks causing excessive loss in man hours. Thanks to Des Byrne in Euro Sales we trialled the LED 7w bulb over are year ago with no failures to date. We are delighted with the lamps and we have sent the specification details to the Airbridge Manufacturers. Apart from the obvious savings in man hours and energy, the lamps are simple retrofit with no modifications required at the Light fittings.
