I think it's like 46%

where do you get that number from? just a random guess?
its unlikley seen as supra has 49.7% at 2100mA

Just what I thought I remember seeing must be 56.

nah 1400mA is 56% and 2100mA is 49 so at 1750mA you are looking at ~52%.

And it is 52.87% if you are rounding to the hundredth decimal point.
Im usually not this snarky but you came off a bit "hot" to me...take care though, friend, keep it Lit !!
Edit: Regardless of the accuracy of @Airwalker16 's response, it appeared to me he was attempting to help you, and you could have simply acknowledged his effort and graciously pointed out his incorrect data in your reply to him. Yeah, I know I prbly should have responded in a more friendly manner as well...I suppose I too am an imperfect being ripe for criticism, meep moop morp

Yes but I own the lpc 150. Could I run the lpc150-2450 thru a hlg 185-1400 or 240-1750? Moreover what happens if you hook two drivers together at different drive currents?(Can you)

Hey supraSPL great info buddy much appreciated.... I was wondering if you have a chart like the ones you posted earlier in this thread that include the hlg320h-c series? Id love a quick guide for how many of each cob they can run

its real easy
pick a current (ie 1400 mA)
what is the voltage of cob at that current ( http://pct.cree.com/dt/index.html) > 34.84V
read maximum voltage from 'constant current region' of > 229V
229/34.84= 6.57, you can run 6 36V 3590s at 1400 mA

Havent been able to find anywhere to buy it yet.... Someone told me it was coming out this spring on some forum so ive been keeping an eye out for it and finally pulled the spec sheet the other day
