I am confused with the output of the Cree Q5 at the following output levels:

350mA
700mA
1000mA


I was on www.dealextreme.com and they say at 1A is 228lm but I forgot where I saw this before but somewhere else said it's 273lm at 1A. If the Q5 is 228lm at 1A then that makes the SSC P4 a better buy (cheaper as well) because it putsout 240lm @ 1A.

DX claims the following for thier Cree Q5.

350mA: 107~114lm
700mA: 171.2~182.4lm
1000mA: 214 ~ 228lm


So what are the lumens for this LED at 350/700/1000?? Is DX right or wrong?

Thanks in advance.
