Beware that they often overheat and burn out and/or flicker. It seems to ne about 75% fail, while 25% last.
Almost every LED product out there seems to have been designed by bean counters.
LEDs do not like heat. If it's too hot to keep your hand on, it's too hot.
I always look for massive heat sinks and good thermal coupling.
God knows how many LED installations fail because of poor thermal design.
LEDs that should last for 100 years, fail in months.. but they were bright while they lasted.
It pains me to see so many people swayed by marketeers into buying something that should have never been made.
And, yes, I usually need 10 times the quantities of LED emitters that others need... But once I get them in, they run till you take them out. These are great to put in places where maintenance is a royal pain in the ****. These days, emitters are cheap, but labor and time costs a lot.
Either do it right, or find time and money to do it over and over.
For intermittent use, a lot of these designs have acceptable lifetimes, but leaving them on for hours or subjecting them to voltage surges, like alternator load dumps and inductive kickbacks, kill these things.
I often run 100 Watt emitters arrays at 10 watts, as it's in a sign, 30 feet in the air, and a real pain to get to.
