I am just about to buy the components to build a 4 COB light for a 2'x3' area. Full grow, seed to harvest.

Hi, After using the cheap China made lights, I have finally decided to try COB'S this time. I was wondering if single Citizen Clu048 1212 would be sufficient for 1 plant in a 1ftx1ft area. I'm expecting it to run on 50w power. In addition to the COB, I'll be using 5x 5w led lights as a...

This light build is for a small area, and I am using some inexpensive Cree CXA2520 and 2540 cobs. I must have gone through 10 sketches/schematics based on different cobs and current options for a small space (2x2 or 2x3). After jumping the gun and ordering some HSUSA heatsinks (2@ 21" x 5" and...

Hi guys, first time poster on these forums. I've been studying up on what I want for my first build but had one question regarding driver amperage & canopy penetration. Has anyone found a particular Mean Well (700ma, 1050ma, 1400ma) that is hitting the sweet spot in terms if dense fully formed...

Hi I figured it was time to start a new thread about where Cobb lighting will go from here Do people want Cree Cxb 3590 chips or cheap knock offs . if you could buy a quality DIY light would you or rather build it yourself. As a long time grower I know that it comes down to your garden. And...
