We have done a lot of LED conversations for commercial retail stores a few years ago and now we are seeing a ton of these lamps failing. We did not supply the lamps it was from the customer, but these lamps where from the top couple lighting companies. They replace them under warranty, but still after how many I have seen fail I'm on the fence about if I was to supply the lighting.
That's good stuff. I have spoken with several manufacturer reps about conflicting specs, longevity claims, etc. I was pretty frustrated with trying to find some high wattage LEDs to replace MH, and was troubled by claims that an LED of 1/3 the wattage could replace MH. I can see 1/3 the wattage replacing HPS because of such factors as S/P ratio and maintained lumens, but an LED replacing Metal Halide is going to have to be watt-for-watt to get the same light output.
That means the customer isn't going to save any money on his electric bill, he's just going to have a gimmick product
But I was also finding too many of them saying they were discontinuing production of some higher wattage LEDs (60+ watts) because of reliability issues. Lower wattage LEDs seem to be doing just fine, though, especially as incandescent replacement
I would be curious what kind of warranty would be offered by the OP if he's the one supplying the fixtures. Every type of light can have premature failure, manufacturing defects, etc. Where are the fixtures coming from - local supply of some sort, or online ordering?
If I were on the hook for warranty work, I would want something that I can get off the shelf instead of having to reorder, ship bad parts, etc.
