From DEs to LEDs

Here are a few pics from my last round.. The Cob rig pulls around 600watts on 9 Citi 3500k.. I should have numbers in a week or so.. I also had a single 135w Quantum board over a 1 plant.. i will have numbers for that aswell.. The rest of the room held 3 DEs for 3K..1 DE per 4x4 area which is really just over kill as i dont run CO2..

So my plan is to replace the DEs with 600watts of Quantum Board per 4x4 and get close to the same yield.. I normally pulled 1 to 1.5 per light.. Nothing epic on yield but it is what it is.. Below are some shots before chop..

Here are my newest QB rigs. Going to be used to light a 4 x 8 space.View attachment 4002619
Details on the QB rigs..

Each lights holds 2- 240-1050A which when turned up will hit 300 to 305 watts at the wall for a total for 600 to 610 per light.. All heatsinks are slate 2s. The frame is cut to a 3 x 3 layout.. The boards are spaced 11" from edge to edge.. And when they are installed the outside boards will be close to 11" away from the wall.
