Anyone know the efficiency of the CXB3590 3500K DB 36V at 1050A and the watts its putting out? Ive been looking for a spread sheet on it and not finding anything. Thanks in advance

Comes in second behind the cxm22 if these numbers are correct. Everything i have dug up its 66% efficiency on the DB

yeah a lot of people have been saying that for a long time. take it for what its worth. no photometric test has ever held up those early cree efficiency numbers. we know they work (along with other chips). theyre fine chips just dont kid yourself that their $35 chips are really any better than all the other chips in that test near it like the $17 luminus and $22 1818 gen6.
if you wanted to spend $35 on a chip instead of buying crees you could buy vero 29C and citi 1825 gen 5 or gen 6 all of which are as good as the CXM22 at low currents and actually offer an advantage to all the chips in this test above 75W
those tests above were done on 2 different days with two different ambient temps. its the same cree chip in each test so you can see what a few degrees can do.

Have any side by side grows between a CXB and a comparable model? I would like to see them in action before pulling the trigger on a cheaper chip.

Honestly man, you will get pretty much the same results from all of them. You might be able to put out a few more photons with a certain chip, but are you to the point in your growing that it will really make a difference? Pick a chip that suits your design. Want the lowest startup cost? 1212. Running a bunch of chips at low power? CXM22 looks great. Running a few chips at high wattage? Vero 29s are excellent. Want to spend a bunch of money and hang with the cool kids? CXB. While efficiency is important, it isn't the only factor to consider.

Efficiency is one of the biggest for me, I rather spend a extra grand and make back 3-4 over its life compared to one using more electric. Plus i can get a more even spread with 20 CXB running at 1050 and still have plenty of penetration.

Then there's your answer. CXB it is.

he wants efficiency there are over half a dozen chips more efficient than CXB, some are more expensive, some are half the cost
in no order
vero 29C
citi 1818 gen 6
citi 3618 gen 5 and gen 6
citi 1825 gen 5 and gen 6
cxm22
cxm27
cxm32

This is also true. But op seems pretty set on Cree.

Honestly been out of it for a long time and simply do not know where to start with a new Chip. How much better are the cxm32 and what are they going for?

Or even the 1825, i see you sell those in the 6th gen. Im going to imagine those are more efficient than the CXB and the same price. What are the driver mathch ups that are used?
