Lighting And there was light

[Loud Pipes]

Just finished my cob light this morning. Its composed of 2 hgl-185-48A drivers and 4 citi 1818 3500k 90 cri cobs-120 passive heat sinks. With these drivers I had to wire in parallel so there's a few more wires than most builds. When I got done I plugged it in and guess what-it worked! I have it adjusted so each set of cobs draws 120 watts-240 watts total- and even there its incredibly bright. If I crank it-holy moly! Now if I can do this anyone can. I have very limited electronic knowledge. I won't have it my grow room until my current grow is done. Here's a couple of pics

Right back at you. Trying to convert thousands of members to a better light source is not an easy task. These DIY and quality cob lights save people money every second they operate. I wish I could post the pictures but I have some sphere specs showing a 36 watt cob vs a reputable LED vendors 300 watt light and you would not believe me but the cob produces a better spectrum and more useable light. Everyone here is probably sick of hearing me talk about efficiency but that's the single most important thing in a grow light. Pretty fU€K![HASHTAG]#g[/HASHTAG] crazy right?!

Was sitting down enjoying all the white light in my groom today and I noticed something very obvious. The 280 watt draw mars 600's don't even come close in the amount of light being emitted compared to the 300 watt DIY I made. Maybe Half at best... COB's are where it's at

How many watts will those drivers push? Been studying for my next light build, it appears if you want high wattage cobs it's best to run them in parallel.
