    Does anyone want to help me find a driver or explain it to me? I looked but there are so many opinions on drivers for all kinds of hlg models and the threads usually devolve into chaos before there is a clear answer.

    Thanks in advance!

    480H-C2100- QB 120 with Molex connector is recommended for 1 or more boards in parallel or in series. 300V rated Molex connector allows upto 10 Boards in series. Boards feature connectors on each side for daisy chaining power to next board. for higher power parallel application, wire each board separately without daisy chaining to avoid voltage drop after first board. Recommended drivers

    So this, 480H-C2100, will power 8 boards up to max wattage?

    @raratt said "8x70=?"

    Well, 8x70 /= 480H-C2100.

    So I am back at square one right? Because 8x70= 560

    Thanks!

    I have a bit of reading to do.


    @NGA - good copypasta. $144 for a driver sounds high, and according to @raratt it doesnt work for my application. I'll do a little reading I guess.

    I was trying to save time, I might just end up buying a set of blurples for my 8x4 tent. I hate wasting time researching TIME = MONEY. Which is why I am more than happy to answer in full in my area of expertise.

    @shawnery That looks a lot better. Can you send me direct links to make the purchases?

    This is a veg tent, but if I can flower it I wont complain.

    You are a GD monster! Thanks so much for all of the help. I owe you one!

    I was just doing the reading myself and picked out a few things, then BOOM "Rollitup - New reply to watched thread" with all the answers!

    Do you work for an affiliate?

    Out of curiosity why do these need heat sinks and the QBs don't?


    I can get 16 QB120 boards - $479.99 1120 real wattage and 4x HLG-320H-48B - and be done.

    vs the aforementioned, which adds an additional $150 in heatsinks.
