Hey guys, need some help wiring my newly arrived Photoboost strips. Im not too savvy in the electronics world, so I'm not really sure what equates to running the strips at 1400 ma vs. 1900 ma would do for me. In the greengenes youtube vid, he uses a Meanwell HLG320h-c1400 for a 2x2 set up (8 strips), I have 16 strips and want to build a 4x4 set up, would I use two of these drivers?

As @ANC said, 320w is way too much in a 2x2, the light in the video is for a 2x4. You want about 30 watts per square foot, so 480W in a 4x4. I don't see constant current HLG drivers that match well with 16 strips, the current is too low or they don't have enough voltage for 16 strips in series. You could go with two HLG320h-c1400 with A or B dimming. Another option is an HLG-480H-54AB and use 8 pairs of series connected strips, then connect those pairs in parallel. It's a little more wiring, but then you'd be working with 54 volts rather than about 216 volts and just one driver.

Hey guys!

How many eb gen 2 strips can I put in a

ELG-240-C700B?

Thanks :weed:



I would like to fit 18 but am worried I can only do 17?

1 ft or 2ft?
2ft makes sense but would be under powered (could get more light out of the strips).... you can run them at up to 1 amp each without cooling
18 will fit

I'd get a constant current 36 volt driver and run them in parallel (in groups of 2)

2 qb288 v1 boards and a hlg-320h-c2100b driver wired in series (with potentiometer) is only giving around 107w output? Anyone know what I did wrong?

It would draw 107w if the boards were in parallel rather than series.

Ok, the driver connects to the positive of one board and negative of the other board. Then a positive and negative are connected between boards. The driver actually sits on top of heatsinks not like in the diagram

**edit** one negative terminal on one of the boards is unusable

Ok just went back for another look and the pot is 50k (because he took some leftover parts and I had used 50k to dim 2 drivers with 1 pot). Is this the reason for the missing wattage? Getting a 100k should solve it then? Is it safe for him to continue using the 50k for now until we can get a 100k?

Take the pot off entirely.

That's what I ended up doing. Is it unsafe to run with the 50k pot? Is that the reason wattage was lower than it should be? From the wiring diagram I posted it is wired in series and I should be getting more than 107w (2 qb288 v1 boards and a hlg-320h-c2100b). Will have a 100k pot tomorrow.
