Brother Sforza You Might Want To Wipe The Slobber Off your Heatsinks Before You Fire Your Light Up Again. Now On A Sidenote If They Come Up Missing I Would Look Up The Grower Named Mc130p Just Saying :D

Hee Hee! That's not slobber. That is TIM. The guy I bought the three larger ones from sent them to me stacked one on top of the other. He left the TIM on the bottom of the heatsink from when he pulled them, so two of them have a little TIM smeared on the top of them. It is not hurting anything. I made sure to carefully clean the surface of the copper plate and the copper face of the heatsink before applying a thin layer of thermal adhesive. The light was built to grow my favorite plant, not win a beauty contest.

It is a great looking design and very professional, but I like to keep my driver's remote from my lights. I have a small area and drivers can put out quite a bit of heat. I don't do a lot of turning my lights on and off, I use a timer to do that. If I have to move a light, which does not happen very often, I just unplug it. A grow light is not like a blender or a coffee maker, where you are constantly turning it on and off all the time. I just set it up and let it do its thing.

Is it the cxb 3590 4000ºk DB 61% @1400mA?
Have a great day ★

The cobs are 36v version, bin is cd, driver max current @2.25a so at full power 80w per cob ~47.5% efficient, not counting the fans. It can be dialed down, i would need to check the numbers for passive cooling and how far the driver dims, but i might be able to shut off my fans if i dial it down all the way and have something like a 60% efficent light. I think this is the way to go when designing these lights, have enough heatsink, that when dialed down, you dont need the fans, but they are there for when you want to turn it up.

Bonjour
I agree with you...!
I took a big hs (1000x165x35mm/40x6.6x1.4 inches) and I split it in 4 to use a piece for each cxb 3590 3500k 36V CD I have @1400mA (hlg - 185 - 1400b) I can switch off the fan and the hs is warm...you can let your hand next to the cob...no burn...and with fan @4.5V it is cold...but I never tried it in summer...it is hot where I live...so fan and pot are my summer allies...with hps and no a/c it is not possible in sum...but @700mA and 12V I am sure it will be doable!

I really like the fence post design. It's just really economical in keeping all everything tidy.
