I came across a couple of successful builds with the EB gen2 with no heatsinks. One of them measured temps and it did not go above 50C or so. Both were VEG lights. So is the light I'm planning. I don't have much confidence for flowering under the EBs at that current. Will need a lot of them. Too muc...

I have been eyeing those for a while. Check out "Jared Chen" youtube channel. It's the manufacturer of those Zigbee devices. They have quite a lot of devices that can take your grow room that extra step. Think further than just dimming the lights. They have a new Temp\Humidity controller. You can re...

I have to say, this is my first build and I am a little bit on a budget here, so I dont wanna spend more than 20 bucks on a single heat sink, concidering I need 6 of them. I was and still am in the same boat as you m...

Tony what did you use to fix the wagos to the frame?
I find, at some point, everything I use deteriorates due to the heat.

I actually have quite a few local hardware stores around me. They sell everything you can think of, including metal profiles. Someone on RUI, recently noted that the Bridgelux E3 series ( http://www.bridgelux.com/sites/default/files/resource_media/DS130%20EB%20Series%20Datasheet%20Rev%20A_0.pdf ) ru...

Awesome!
Why the cube shape? why not just a rectangle?

I am talking about aluminum sheets and...
