The dim circuit on the MW driver provides its own current, so all you need to do is open and close the connection between the dim + and dim - wires with a PWM signal. You can do it with an optocoupler and resistor as I mentioned above, or with transistors as you've stated. Use the pi to provide PWM...

I ended up answering this in comments on YouTube. I’ll paste in my reply: “ That's an easy one on those drivers since they supply the 0-10V on those wires themselves. I did mine with a PC817 optocoupler. PWM/ground from your microcontroller goes to the 2 input pins of the optocoupler (don't forget ...

I ended up building a larger light. I have decided to get another strip to add to bring the total to 6 and run it a bit cooler. Its really just for over wintering some outdoor plants Here is the build 5 x BXEB-L1120Z-50S4000-C-C3 (the new Gen 3 thrives at 4 feet) 1 x XLG-240-H-AB 1 x potentiometer I...

@herbie, Sorry for the delay. Just seeing this. The topography was wrong. You want AC DC, this one was DC DC, I think I found a laptop charger that fit the specs that I was eventually able to use, but its much simpler to not use a DC DC boost transformer Hey @bestinc ! I'm new to this game, trying t...

@TEKNIK sorry to be a bother but you're too good of a resource hahha what are your thoughts on the above? I'm still waking up so I need more coffee but your wiring and math looks right to me. I will say it again that using high voltage running strips in series so the voltage exceeds the rated outpu...

I am finally looking at building a larger 4x2 for a variety of plants to overwinter inside. I am looking at the below

6 x ‎BXEB-L1190U-40E3000-C-C3‎

powered by

HLG-185H-C1400B

and wired like attached. Did I make any mistakes? Can I do it better?

Thank you!

Well I ended up doing this to get my feet wet

BXEB-L0560Z-50E2000-C-B3 x2

LED DRVR CC BOOST 12-43V 1.05A (I realized my mistake after)

Still want to build out a larger one but I have time before summer is over. Probably going to add 2 more lights to it because why not?

Thanks, I look forward to it! I have the power supply and dimmer, and I'm expecting the light strips and heatsink any day now. But it will probably take me a little while to get around to picking up the wood and the rest of the bits and pieces. I'll post a photo and a parts list when I get it done. ...
