I bought the UV one, I'll report results when I get it.
Jim@Manafont didn't know to tell me who is the manufacturer of the LED. He also couldn't tell me anything about some other products from his site, other than what's written in Manafont's site. That's a pity, I thought they knew who they buy from.
The second is the Phillips Lumileds K2 TFFC, the first looks like it could be a luxeon, but I can't see the dome. The 4th, I have no idea. the 3rd is definitly a cree.
I got the red and the blue one both from an ebay's vendor some months ago for around $2 each. It was an auction ...I think both are made for the same manufacturer probably Philips
The red is in one 'police' host , the only at hand, with a 5 modes driver...it was a pain in the a$"s to get the guts off in that cheap crap but finally work despite the broken plastic reflector and the dust, very powerful emitters
It was a year ago , my first emitters bought, recently when realize how good the emitters are tried to find this guy but I can't... today all appear to be generic chinese dies. Maybe he's selling other kind.
