I just noticed that each QB draws less current than one of my Veros. If I understand things correctly, I can drive all four V2's with a single HLG-240H-C1750B or C2100B maybe.
Are you sure it doesn't need a heat sink?? I have QBs. A few 260 V2 with 2 boards and the heat sink and the power supply both get too hot to touch. I had to turn them down.
Might be a different lamp but I bought it April so its fairly new and a V2
It's 2 boards @ 260w - so you're looking at the 132's so its 4 boards same amps?? If you can get heat sinks I'd do it. Then you have something to mount the boards to!
Look here - you get everything you need just have to put it together. It's so easy even a grass grower can do it! lol
one atf cracked and is in the dirt!
Congrats sticky.
