Was not happy with the spread of my qb288 build for my 2x4 grow box build. Picked up a dozen of the 3k strips to experiment with and this is what I came up with. Running 8 strips with a hlg240h48a. Will run from 104w up to 290w. Took par readings at 12” in the center. 104w = 334 par, 290w = 853 par. Tested the lights air cooled with no fan. At 240w the frame exceeded 130 degrees. The water cooler is just an external radiator. ![8EADFCA7-DF4F-406D-A315-114F1E176687.jpeg](/data/attachments/3656/3656435-11a426ba592340a41c441944aaf95282.jpg)
