brightest led in lux form factor?

[ginaz]

i just got some SSC U3's to upgrade some older lights. measured in my lightbox they gave me about a 20% increase over the U bins that were in there before. is there another, brighter LED in that same form factor? will there be U4, V2's etc? thanks!

Next step up from U3 is the mythical V bin but I'm pretty sure they aren't available yet. Cree seemed to have stopped at R2 with the EZ1000 die which is what the supply to SSC, and thats the top of the U bin (though SSC could make a more efficient phosphor I guess).

interesting that they show up to a Y bin!
