ExECLED Retrofits for Hazardous-Area Lighting: A Cost Case
LED has changed the economics of every flameproof fitting. The payback is usually measured in months.
The energy saving
The headline saving is energy. An LED wellglass typically draws a fraction of the wattage of the lamp it replaces.
The maintenance saving
The less obvious saving is maintenance. Relamping a fitting in a Zone 1 area means a permit, isolation and labour.
Understanding the payback
Across a plant with hundreds of fittings, the payback on an LED retrofit is usually measured in months, not years.
