So I'm thinking a light upgrade is in order sometime soon. After this grow. I think I'm going to go quantum board route from hlg. I have been looking at two of them pretty seriously for awhile.
The first is the 260w V2 Rspec board with the xl heat sink. This is $370 for the complete kit including driver, boards, and xl heat sink that is just long enough to cover the entire tent 2.9 feet in my 3 foot tent. This one is dimmable 135-285 watts. I was think about this one only with the xl heat sink so that j could space the two boards out and get good coverage over the whole tent instead of just from the center. Here is the link to check them out...

The second board I was looking at was the 320 w V2 Rspec with cl heat sink. This is literally the exact same as the first one with the addition of a third board.
Both of these run the 288v2 Rspec boards, it's just the quantity of boards that changes, with meanwell drivers. I have never ran a quantum board and have only used an Amazon LED to this point so I'm a little noob like when it come to this decision. Right now I'm pulling almost 400 watts from the wall and these pull significantly less. I'm worried that they might now be ass efficient as standalone units in my 3 X 3 tent. If anyone has any suggestions or if you think I'm way wrong about power levels with only one of these lights let me know. And if you think that I should go with the triple board, the 320w,or the double board the 260w and why. Thanks guys!
