So I want to hear people’s opinions on COB LED’s vs QB LEDs. I currently am running 4 100 watt COB LED’s with 2 Citizen 50 watt chips in each light. The biggest difference between the COB’s at this point that I can find is the chips in them but I am not terribly educated in terms of electronics or m…

[image] BrokenHippy: some reason COB lights tend to cost more. This somewhat of a true statement. I’m not sure the differences in efficacy, but they do cost more because a proper sized heat sink is required. No fan dissipate heat, all passive cooling, but they do have excellent canopy penetra…

Generally speaking, the mid power pcb style lights (quantum boards) will have a higher ppf per watt than chip on board styled leds. The pcb styled lights are also usually a little cheaper to put together as well. When using higher end cobs it’s definitely possible to get close to mid power performan…

Those kits from Rapid look very interesting. They use the cree chips and everything which is a great selling point. Like you said I really appreciate the canopy penetration of my cobs the ones I have are cheaper ones and actually have fans built in over each heat sink to so if I can actually manag…

I feel like I’m already learning so much more about both types of these lights. You all are helpin out so much thanks. Do you think the mid range pcb lights are comparable to the cob lights that you might be able to build with the cree cobs for the same or comparable price? Knowing that I’ll hope…

[image] BrokenHippy: kit separately to try to keep the price down I assure I’m you I priced everything out individually, and it comes out more. Secondly, I want top bin chips, not questionable where they came from. [image] BrokenHippy: tuning of the lights from 800 to 400 Some of thi…

That is so good to know that someone already tried to price out everything individually. I totally agree I think the chips make a huge difference with the cob lights in terms of how the end product works out. And yea I totally understand trying to find out how hard you can push the plants. I just…

Cutter has good stuff. Pacific light concepts, chilled tech, horticulture lighting group, and many others all offer diy pcb’s. I have a thread on here that I did one with bridgelux eb series. Others have put up topics with multiple Samsung strips as well. Sometimes it’s just a matter of what you ca…

This is all such good information. Especially for somebody just starting into diy like me. Having all these starting points and everything and getting opinions from other experienced growers is so much help. I’ve already been following one of the diy threads that you did so I’ll have to go back a…

It’s right here [image] DIY with bridgelux eb strips Lighting Hello all! So these are seeming to become popular enough for their own thread. I figure we could try to post all things eb strip related here and could serve as a good reference for anyone that comes along lat…

Thanks so much man. I’m goin through that right now and its so full of exactly the kind of stuff I need to know to be able to build one of these well and without spending to much. Kinda feel like I’m goin down the diy rabbit hole now haha but this way is going to make it so I can get so much more …

Keep in mind It’s a small light and was designed to be a budget build a while back.
