If building a light using 2 of the 288s for a 5sq foot grow space can I use the same driver for my QB304s ? 120H-c1400A and it runs the QB304s up to 185W. I want to build another light using the 288s.
Of course there's a controversy whether to go parallel or series. Something about the boards not be identical. Mine are manufactured at the same time so parallel should be cool. It seems that with a series the board, the plus side the first board would get most power first.
I don't understand what you mean by savings versus original cost.im not sure how much price the equivalent board is on HLG, or what equivalent product that is (im assuming similar to the hlg550 which gives 510watts). did you figure out how much you are saving vs original cost?
2 left thumbs here and trying to figure out if its worth it
sorry, a little new here. i meant if you DIY a QB, i figure youre modeling it off a specific type or equivalent type of pre-built QB like the HLG550 (one that i am eyeing).I don't understand what you mean by savings versus original cost.
My build is more work vs a single State heatsink.
Guys talk about tapping (threading) the heatsink. That's cool and more efficient but I used machine nuts and bolts on this one even though I have the taps. I'm going to tap the cross members on the second one, the heatsink has enough meat to it for a good grip. Gl
My guess, you could build one for between six and eight hundred bucks.sorry, a little new here. i meant if you DIY a QB, i figure youre modeling it off a specific type or equivalent type of pre-built QB like the HLG550 (one that i am eyeing).
That one costs 1050$.
How much would a DIY equivalent cost?
That's the gist of my question - wasnt sure which one you are modeling/price vs price of your DIY project

They have a 600w kit for around $600sorry, a little new here. i meant if you DIY a QB, i figure youre modeling it off a specific type or equivalent type of pre-built QB like the HLG550 (one that i am eyeing).

I think people dim to save power or if the plants are new growth. It would also increase lifespan which isn't really a factor imo.for flowering with qb, is the 16-24 (no dim, not sure why i needto dim unless i dont have enough plants) the distnace from board to the top of plant or just to the top of the bud?
I've been running an original QB S5 bin 304 board ... No stop for over a year ...
18/6 or 12/12 ....
No burn out or issues .....
How do we go about having less shock hazards? I haven't powered up my boards yet. Can they be touched at all when running?Beware of shock hazards when powered on .... Don't just grab rig while lit .

I havent bought one of these yet, just cut them from electronics I dont use anymore.Where do you guys get your power cords (other than HLG)? I need some for new installations, and for some reason Amazon only shows me US$10+ prices for 12 AWG cables.
Home Depot and Lowes sell them too. If you can wait for one to be shipped sites like Digikey sell them cheaper.I havent bought one of these yet, just cut them from electronics I dont use anymore.
While this is good advice for anything electric, if your fixture is live to the touch you have done something wrong. Stop what you are doing (or trying to do) and hire a qualified electrician.Beware of shock hazards when powered on .... Don't just grab rig while lit .
