Bright LEDs

where can i get a really bright LED thats efficient and also pretty cheap?

i was thinking about seoul the 240lm 3watt.

but if i can wire down luxeon rebel i'll probably go with that since its cheaper and its has a better lumens per watt.

Cree is the hot thing now with P4 bin being the norm now but with Q4 and Q5 just coming out now that are about 30% brighter with the same efficiency, Seoul is also popular. Other options are Edison and the Luxeon Rebel. The cheapest prices for any of these are probably going to be Dealextreme.com and KaiDomain.com. Shipping is slow so if you need something very quickly then they wouldn't be the place to look. I like the Cree myself, though the Rebel looks very interesting but working with it would be a nightmare for me (though they do have some mounted on small 'stars' to make things easy). Cree Q4 is rated at around 80lm at 1 watt, Q4 100lm/1watt, Q5 107m/1watt, Luxeon's latest Rebels are rated at 90 and 100lm/1watt.
