LUXEON STAR Power-Light-Source LEDs by LumiLEDs.

6x350mA would make affordable 2.1 Amps on a Dcell Light...

I'm dreaming of cutting the lenses to hexagons and gluing them together again...

And I think heatsinking would be makable too...
(Perhaps without active water cooling...

)

So much to do... And no Diodes to start with... ***teardrops on the keyboard***

And the inner diameter of a 6P or 9P head is 22mm, so much space...

That wouldn`t work, you will have to see one to realise. The LED assembly is made of 3 parts- the board with LED on, the black body shell and the solid clear plastic lens that acts prismatically to form an effective reflector without resorting to silvering. The body shell holds the clear lens in place (it just clips there), they can`t be cut smaller than the diameter of the shell. No, I reckon 3 will be more than enough, believe me- they are very bright. 3x18 lumens= 54 lumens which if memory serves me right, is a little more than a normal 3D MAG bulb puts out. Plus it is a smooth beam, no rings or dark spots at all. You will be impressed!


22mm inside a 6P`s head? You`d possibly get one in but it would be a very tight squeeze and the aluminum LED board would have to be cut so small there would no longer be any convenient solder pads to use. The body doesn`t come off the board easilly to allow soldering closer to the LED either.
I`m guessing the e2 is narrower again, right? In which case the dream of putting one in an e2/e1 will stay a dream unless SureFire get hold of the bare LED versions and design a lens to fit.

Sorry to rain on everyone's parade, but the $4 price being bandied about is a "soft estimate" for MULTI-THOUSAND quantities (as quoted to us). And yes, they are VERY sensitive to over-voltage (fried 2 myself). They can be driven up to 750 ma, but heat sinking becomes critical. We've supplied prototype flashlights to Lumileds, and have several circulating around here.

I think most of us had felt that would be the case

Well, on a happier note, would you like to make any comments on thier performance Scott?

That'd be telling.
OK; the color temp is in the 4500k range; the beam pattern is clean 'n tight, sharply defined. At 350mA, the light output is less than an incandescent of the same mA draw, yielding less light for the same battery life. The LED life is also not being quoted (prob. under 10,000hr).

On the up side, Lumileds is predicting a 50% improvement in light output/watt shortly. This will likely put it on a par with an incandescent. Of course, the shock resistance also stays as an advantage.

First use will likely be in a consumer desk-style lamp (by others). High style, high tech, high bucks. We'll have a flashlight model out as soon as the bright version is avail. in commercial quantities.
