From where did you obtain the driver? Also, how long did you run it on the Kill A Watt? For a few hours? Or just when you first plug it in?

If you want to use multiplication, you would have to multiply using the inverse of the percentage. 1/x 1/.94 = 1.0638 195*1.0638 = 207.45w 1/.86 = 1.1628 195*1.1628 = 226.74w

Are you running at 50w or 24w? If 50w you'll want more spread between COBs most likely...?? That's something you want to think about. I'm doing 50w, 4 x COBs on a 40in x 5.88 from heatsink USA with good results. I'd still have an oscillating fan blowing across the heatsink every rotation. Cheers!

That's really awesome! good for you man How are your results on your CXB3590 lights so far? We really love ours running at 50w

Hey Supra, once again thanks a billion for all your posts and inspiration on here! Currently building my second CXB3590 unit. This time with 6500k. I'm going to throw down my 2 cents on a few things I've seen posted around here, whether you want it or not :P Pot size: IMO this is a huge factor...

Don't mix thermal pastes. If the heat sink already has paste, then use it. Or clean it off and apply your own. But once it's down, you can't lift that COB off. If you do, clean off all the thermal paste and re apply. Sry for grammar on an iPad.

Oh come on supra. This is the thermometer you need you cheap skate. :p same one I got http://www.amazon.com/ThermoWorks-Super-Fast-Professional-Thermocouple-Thermometer/dp/B002GIZZWM/ref=sr_1_1?s=kitchen&ie=UTF8&qid=1446254704&sr=1-1&keywords=thermometer You run your chips really low wattage...

Excellent Once we get more lights I want to try running them like this (drawings below). It would have great penetration for cannabis xmas tree shape (1/4 turn daily). Fewer but larger plants are easier to maintain imo. Have you ever seen anyone run their LEDs like this? It would obviously eat...

Your new video is good, it's cool to see the progress. You got your stuff dialed in nicely. A+ buddy. I've seen a lot of recommendations for HID growers to rotate their plants 1/4 turn every day. To improve yield, plant structure, etc. Is this something you would want to do with LED too?

Thanks for posting! I need to check one of my COBs now. When I was screwing down the COB onto the heatsink, I had it in one of the IDEAL holders. It popped out of place momentarily and I didn't realize. I continued to screw down the IDEAL holder and I may have damaged it. I don't really like...

Hey guys. Oh I don't put too much thought into it anymore. After swapping CPUs hundreds of times, and they're all running about the same temps, I just stopped caring lol. I just put a dot of goop on, slap down the chip, and screw it in. It is best to screw alternating back and forth to...

Thanks for the info and your expertise! It's funny, if I would have found this website a year ago I would have strongly advised against sanding your heatsinks to apply thermal paste. I guess you learned it on your own though lol. I have a huge amount of computer expertise and knowledge, and...

Hey Supra, Thanks for the quick response! This eases my anxiety. :) This was just in my kitchen. I let it run for an hour, then used a high end meat/candy thermometer (I'm a hobbyist chef) with a drop of water on the back of the heatsink behind the COB. The highest readings I saw was 140*. I'm...

Hey ya'll, Quick question. Are my LEDs running too hot? I ordered based off of Supra's chart here: @ 56.3% (4) CXB3590 3500K CD 36V @ 1.4A (49W ea) $190 (1) HLG-185H-C1400 $65 196 dissipation W -> 85.7W heat -> passive cooled heatsink 10284cm² -> 5.88" X 38" heatsink $72 (could split in 2 to...

Ya... I think I might build them without lenses now. :-/ I really don't like all that heat suffocating the chip. hm...
