You actually did refer to UL as though it was an authority.I never said UL was a law so please don't put words in my mouth. It sounds like you have an axe to grind about UL. I think they provide a decent service - what would have in their place - nothing?
The statement of compliance to an international standard similar CE (I forget what the standards are that CE refers to and if I did I would be remembering the medical devices standards since that is what I design to) to from a reputable standards lab as opposed to that of a self serving bigoted money grubber like UL.
Actually that is the deception. They do not "get to say", they BS the buyers and the public into thinking they "get to say". UL is NOT a requirement-ANY testing would hold water over no testing in court. The ONLY thing the UL is is a TEST LAB... NOTHING MORE! The little UL symbol is nothing more than a trade make that they force companies to pay protection money for. Protection money in the form of over priced tests ... As I said, they charge $5000 just to shuffle papers about.Note that when assigning blame for fires and such, the lack of UL certification has a lot of weight. I'm pretty sure there are similar bodies (governmental or not) in most countries. Whether they are "deceptions" or not they get to say if a product meets safety criteria.
Show me a CE and I will consider it. A VDE and you have something to brag about. UL is garbage, and while garbage is better than nothing, give me a 220V safety rated failure on 110V before you give me a UL passing grade any day!
UL is nothing more than another ego maniacal monopoly. They force companies that want to sell in the US to pay $5-20K to THEM on substandard tests that are already exceeded by the international ones that were already payed for.
The power level is not the issue, what is at issue is that many power LEDs require that the thermal pad be epoxied to a heat sink and isolated from the circuit. Most experimenters that are using much more powerful LEDs are using stars, ie they are premounted.Also, I know a number of experimenters that are using much more powerful LEDs than that. I don't think it is beyond them.
If they can not get the thermal contact the LEDs will burn themselves out.
I have mounted ones that can be handled, worked with stars, have assembly equipment at work that can handle the silicone lens parts, and will likely have luxeon rebels in production in a year or so.
