Cree CXB3590 Build

This is my first build, I think it went pretty well. I had a lot of information from forum members and Robin from Northern Grow Lights. The Meanwell 1750ma driver is on the outside to avoid any more heat in a sealed system with CO2. Avg temps around 85-95F. The CO2 is running a solid 1500 ppm when the lights are on. This is also a 6 bucket recirculating system hydroponic system.

*****Both Pacific light concepts and Northern Grow Lights packages came super fast considering I live here in Maine. Both of them have great prices also so double thumbs of for them two.****

4x passive heatsinks from northern grow lights

Oh he'll ya dude that's sick as fuck.

Looks nice great job

Thank you.

Im new to the Led scene honestly barely contemplating it, i have a potentially stupid ? But i must know for my peace of mind lol when u grow with led do you want both ur colored lights and "white" lights on at the same time or opposite? Sorry for the noob? In advanced

What size heatsinks? How bout some details on this build.


Looks great by the way, nice work

nice job.

For what I have read cobs have low uv and ir. My other to lights apparently have both. So I have them on at same time but i am also selling those to make more cob fixtures. The heatsinks are 140mm. Keeps them nice and cool when lights turn on ill post picture of temperatures. What i have noticed so far is that the driver runs at 129f definatly glad i put it ouside of room. Sealed room is a new situation for me and im running without a chiller which is being the bane of this grow. Water temperatures have been higher then 75f. -_-

Looks great.

those heatsinks look so much bigger with cobs mounted on em,BOSS setup man!!

do u still need an airco with the leds in a sealed grow room?
