I'd like to here some comments from some LED experts on whether these are compatible to CREE. I'm pretty sure XP-G are rated 493lum max and have flux = 139lum @ 350mA.
thunder, do you have a link to a spec sheet? I would be interested if they are somewhat comparable to crees. I would order over 100 LEDs myself at that price. Also do they have red and green? Last edited by sphelps; 03-17-2011 at 02:44 PM.

Cree blues and whites max out at 1000ma and 1500ma respectively, but most people run them around 700ma.
If these china LEDs max out at 700ma, then you would probably want to run them at 500ma. So they're not going to be as bright as Crees. I think this is a case of you get what you pay for.

You may want to look at the LEDS from Satistronics. the blues are very good, but not so sure about the whites as I have never tried them. Prices about the same and the shipping is fast.

I have used the 3w blue leds and they work well, but I don't have any Royal Blues to compare with, but there is some info on nano-reef's that the two are almost identical. I am using the Sure drivers, cheap and seem to work well, but do get quite warm when run at close to capacity.
the leds are on a nano reef so just using a 24v laptop powersupply. The sure drivers are quite forgiving for voltage and you have a wide range depending on number of LEDS used. http://cgi.ebay.com/3w-LED-Driver-MB...item3a6442f9f3
