Word is SSC is coming out with a 370+lm LED sometime this year. I think that's based on 1A driving. Cree should have ~275lm in thier R2 or was it R4..I forgot.

Right now if you're doing DIY and want good bang for buck and still very respectible bright (some may say blinding) the SSC P4 U-bin LED's at DealExtreme are hard to beat at ~$5.50/ea where as the Cree Q5's are $9.00/ea.

The SSC P4's get 240lm @ 1A (if you win the lottery) but after the conversions of ~85% effecient optics plus 85% drivers it comes out to this :

240 x .85 x .85 = 173.4lm @ 1A after effeciencies.

That's if my math is correct. Still working with two LED's gives you 300+ lm.
