DIY with Quantum Boards

If ya can build a rectangle out of aluminum frame 12" x 45" your in luck.
Just mount em to the frame,
wire up yhe whip to the ac side, hot, neutral, ground.
Then run your qbs in series, +,-,+,-,+,-,+,- back to driver leads. A few screws a few connectors. Easy peasy

Maybe. Still waiting on a quote (been 2 months). The osram square is pretty darn good and at 250ma where we run the monos I would say there is very little difference. A sphere test will tell

I am trying too light a 4x8 tent but with financial restrictions will have too peice it together. My plan is too buy QB288 Rspec boards with heat sinks one set at a time.Ordering the drivers separate.The goal being 4 sets.Would the HLG-480H.... Be the driver I want? Second question what do the extra numbers mean HLG-480H24 HLG-48024a. Third question which one has dimming ability

Nice top density i need to work on spreading my canopy out more with lst. I really didn't fill out the room as much as i wanted to. I left a lot of open space. I just kinda slacked on the garden this run. How many watts are you running those boards at?

Good deal dude I would have picked up the qb120s when i added to my v1 qb260 watt kit if they still sold them still in singles cause I lack a light budget lol

I ended up adding the 2 Atreum 144.2s which are pretty similar no heatsink and all.
