Awesome! Thanks! That is probably pretty close. Thats the current I run. Though not sure if you used AB bins. Mine are z4 because thats all supra or anyone else had at the time. Either way gives me a good idea.

That is the calculated efficiency of the Z4 @1.4 amps....All 3k Cree CXA 3070's emit 4.66 joules/PAR Watt, regardless of whether they are the Z2's, Z4's or AB's......

Edit: should be very close! I took everything out to the 2nd decimal point
