Oh god.... what the hell happened when I was gone? This is HUGE! Did this just happen over the last few days, somehow they started mass selling 445nm diodes?

LOL! Do we have a reliable source for these diodes, or did someone just stumble across a DLP projector?

As long as they make these projectors we've got a reliable source. Round 3 of the group buy for diodes is currently active.

The green is produced by fluorescing a phosphor disk with the blue light and the red comes from an LED source

It's kind of interesting how it works. It uses red high-power LEDs and a phosphor wheel that is illuminated by the blue laser light which causes the phosphors to fluoresce to make a brilliant green.

EDIT dammit Dave.. fastest fingers in the west.

Ok, cool. And is it just me, or are these diodes more powerful than anything we have right now? I've heard some people say rated at 1 watt in the 5.6mm package. That's higher than anything I've ever seen.

As of the most recent testing of the diodes from the A130 projector, 500-600mW has been obtained but only briefly. It's a little early to tell how long they'll last, but I intend to meter the lasers while they're still in the projector to estimate a safe power level for maximum lifetime.

By "only briefly" do you mean they died at those power levels? Even so, that's still way up there with 8x/12x diodes.

Heh, that would be awesome but I think the heat generation at those power levels would turn the diode chip into a crater - it's already crazy the power outputs we are getting from a 5.6mm diode can
