"Why are our LED corn bulbs failing?"...or sometimes we hear:"Our retrofit LED lights are not as bright as they used to be"...or even:"Why are our LED corn-lamps dimmer / less-bright now?"We hear this a lot with high-power corn-light retrofits fitted in low-bay/highbay lights. Many companies sell LED bulbs designed to replace the metal-halide or sodium (SON) lamps in industrial floodlights, high-bay and low-bay lighting. We've never sold or installed LED industrial corn-bulbs as they haven't met our specs. ...but we've analysed a lot of LED retrofit corn-lamps in customers low-bay/high-bay lights in warehouses and industrial buildings. Sometimes the lights have stopped working or are far less bright after 2-3 years. Why? LED corn bulbs need open-air to stay cool: LEDs are outside, hot electronics insideAre your LED corn lamps retrofitted inside a low-bay / higbay light? The heat builds up inside the body of the low-bay light or high-bay light. This can start to destroy the bulb's electronics and LEDs. The LEDs can fail, change colour, or start dimming / reducing in brightness. Did you know hot LEDs are not as bright as cool ones? So overheating corn-lights might be less efficient than previous-generation metal-halide or SON (sodium) lightings. What are the alternatives to retrofitting LED corn-bulbs?We don't sell corn-lamps as we need to promise our clients a very long life from their LED industrial lights, particularly in high areas where access to replace them is expensive.LEDs and LED-drivers are the expensive part. It's usually false-economy to keep your existing light-bodies as the bodies are the cheapest bit. This is how we make LED high-bay / lowbay lights instead: Separate LED driver to keep heat away from the LEDs:   (Top-model)The LEDs are attached to multi-serrated metal cooling fins (‘heatsink’) to give the LEDs a long bright life  Budget 'UFO' model (good alternative to LED corn-lamp at a similar price). Retrofit corn-lamps are like old lights, they lose light by bouncing it around inside light-fittings:  Our LED high-bay/low-bay and floodlights mount the LEDs on the outside of the light. So all the light comes out where you need it for maximum efficiency (lux-level at the ground per watt of power you spend):  Written by Stephen Begg, industrial lighting project-designer.
