Scroll down and see the certifications. This company and Sharp are different colored horsee's...
Most cheap chip companies do not offer anything.
What's my definition of a good 10 watt chip?
24/7/365 for 7 years.
Those complaints are because NONE and I mean ZERO of these chips are rated for use at voltages higher than TEN VOLTS. Drive them at 12 volts or higher and watch with horror at the milliamps. They start off with 140% rated overcurrent then go to thermal runaway.
It's nice to have my small assortment of test equipment. I can test and VERIFY that these TEN VOLT chips need larger heat sinks than what 90% of the so-called 10 watt chips call for. Another boo-boo? You bet your donkey it is...
Adding a fan effectively TRIPLES the effective surface radiation area of the heat sink. Yet another Dick & Jane verified series of experiments.
Rather than re-invent Frankenstein's laboratory for making up a series of hunt n peck trial and error, I chose to list chips from a company I know and with the 12 volt to 10 volt driver AND a fan cooled heat sink, I am ordering a bunch of these kits.
I have yet to kind a standard "RV LED Lamp assy" that serves my purposes. They burn hotter than snot and no way are they going in or near my teak. The higher adapter voltage for my 24 volt system is a nice feature.
All my higher wattage 30,50, and 100 watt chips are SHARP brand. There are 13 burning in a store from 4:30PM to midnight, since 2012. No failures.
And my ultra high capacity 300 to 500 watt monsters (this figure is ACTUAL WATTS CONSUMED) have served well with nary a chip failure.
Wish I could say the same about "recommended" COB lights. My opinion is they are garbage. I have about ninety of them and 100% have segments dark.
