About a week or two ago I built a 10 vero 29 cob fixture and powered them at 100 watts each to replace a 1000 watt hps se fixture over a 4 x 4.
I have a couple 12 Cree cxb3590 cobs fixtures right now that I was powering at 50 watts each (600 watts total) and it does awesome. But I wanted them to light up a little more so I replaced the drivers in them with meanwell hlg 240 1750b's to run them at ~62.5 watts each instead.. so that left me with 6 of the mean well 1400b drivers.
I had already just finished replacing my veg and mother lights (MH and t5 fixtures) with cobs fixtures I built so I needed something to do with the 6 now unused drivers.
I stole the layout from growmau5's canopy 10 build, mine is a much more basic version of that though. I did a 10 cob Vero 29 gen 7 C's (~68 volts each,they are the most efficient Vero 29 Gen 7;s you can get, by about 15% or more efficient that B's and D's) 3000k 80 cri and 3000k 90 cri mix and powered them with my old drivers at 100 watts each.. figured that would be fun to do..
After it was build I was so impressed with the output and how amazing it completely covered with deep penetration a 4 x 4 I decided to build two more!
I have apogee par sensor, was getting 900 or better ppfd all over the canopy at 24" and 1300+ at 12". After these lights are built I am going to hang one and put a 4 x 4 grid on the floor and measure many different points to get more accurate results. I have a apogee 120 sensor, and that does give lower than accurate results with LED's, so the numbers are actually quite a bit higher.. I may order a apogee 500 so I can get accurate measurements but they cost like 500 bucks.. ouch
Anyway, here are some photos of the last build and here are photos of the parts that just came for the new builds.
