I'd recommend the c1400B since you can dim it with external potentiometer.
Didnt you have a frame kit already that was in production...like a yr or so ago? Aluminum plate, square with an "x" grid pattern that held the driver and mount the cobs on the corners. You could join more than one frame together or something along those lines or am I thinking of someone else?
Anymore of the CXM 22 light engines on $33 special available ?yes soon im almost there hopefully just after christmas
That spacing looks perfect for a 2x2. I consult a few vets and sick people on how to grow there own meds. My biggest hurdle is lighting in that I need a reliable source for parts. I'm the first to promote the Quantums but if I can't get them reliably then I have to look elcwhere and COBs are proven.NGL had a frame like this one:
I have this. I removed the lenses seemed all they did was store heat....

yes the site inventory is accurate, best to check there first as were getting down to the last and a bunch got sold before i saw your post.Anymore of the CXM 22 light engines on $33 special available ?
my CXM22s pull their weight. pun intended. im happy with them and my budget 1212s by the case. if youre not pushing them too hard they stay pretty efficient.@CobKits Will there be a restock of the 120mm CLU048 soon?
Running at 1400ma.... They are just warm. My 4 cxm build puts off better light than my Vipar and Mars together! With less heatheatsinks? only 133 mm from here on out
They adjust MAX output voltage and current for the driver. doesnt mean you will be operating at max voltage or current, the array has to be able to operate in those parameters. for example, on an hlg185-48A which has about 4A, max voltage is about 53.5V so if you put one ~50V cob on there that is 100W at that voltage, or ~2A. so regardless if you crank up Io, you wont get over 2A@CobKits -- can you give me a brief explanation of how the two adjustments (Volts and IO) on a -48A driver function?
Thanks!
Those are some massive angles you are using! What size space will this light cover, and how many watts per cob?just need to wire this bitch up! ready to slay it in the test tent

Thanks for the response. I don't know much at all about electricity, never wrapped my brain around volts/amps/watts. All I know is that when I have a Kill-O-Watt meter hooked up and I play with the adjustments, both can impact the final watt output. I should have just asked which you recommend using to dial the light up or down?They adjust MAX output voltage and current for the driver. doesnt mean you will be operating at max voltage or current, the array has to be able to operate in those parameters. for example, on an hlg185-48A which has about 4A, max voltage is about 53.5V so if you put one ~50V cob on there that is 100W at that voltage, or ~2A. so regardless if you crank up Io, you wont get over 2A
likewise, if you have a cob array on there that maxes out the drivers current at 52V, turning Vo all the way up stil wont deliver over 52V
the driver, like the COBs, can only operate on teh voltage/current profiles in their datasheets
if your plants can take it, and your heatsinks are sized appropriately, crank it upThanks for the response. I don't know much at all about electricity, never wrapped my brain around volts/amps/watts.

this will easily do a 4x4. half of the test tent(4x will be this light set to 630 watts at the wall or whatever the 630w DE CMH 3K-R hits at the plug. not gonna divide the tent up with a barrier so it wont be a true side by side even comparison but it should be close enough to get an idea if the results are way askew in one direction.Those are some massive angles you are using!
