Hi. I started this thread at the end of last year but started nursing school in January and free time suddenly disappeared from my life. Finally I got some time to keep working on this project, so here are some pics of the cabinet ans the light. I will post more pictures when I finish it. Thanks...

I can't edit my post but when I wrote it I was thinking about my gen 1 strips and a 24v. With that setup you need to adjust voltage and current to dim the lights really low cause the voltage only comes down to 22v, but with the 20v drivers the vltage will go down enough to dim the lights until...

I would also use a constant voltage driver and wire in parallel. 185H-20A, 240H-20A, 320H-20A, 600H-20A. Bigger drivers are more expensive but allows you to add more lights later. Note that the bigger driver, the less you can dim your lights.

You can use that driver but you are going to have to combine series and parallel wiring. You can have up to 18 strips on that driver if you combine in parallel 2 groups of 9 strips in serie. You have to do 2 groups in parallel of 5 strips in serie to wire your 10 strips. Voltage will be 97.5v...

I think the hlg-185h-20a is only 185 watts. Can you really push this one to 200 watts like the CC version? Can slmeone tell me what color temperature work better with this gen 2 strips? 5000k +3000k? If so, what ratio?

Thanks. That is not exactly my set up, I just wanted make sure that I understand how this serie/parallel combination work. I read too much about thermal runaway and got scared but after understanding how it really works it is actually very simple. I think CV +CC drivers are great, they are safer...

Thanks!

If I have a HLG-185H-48 and 6 x 24v strips: Can I make 3 groups of 2 lights each wired in serie, and then wire the groups in parallel? Or does it work only with constant current driver?

I just realized that bridgelux doesn't mention in the datasheet that these don't need a heatsink like they did for gen 1. Do these need a heatsink?

Thank you!

Thanks! Merry Christmas!

Hello I read that if you multiply your radiant watts by 4.66 and then divide the resulting number by the area of your plant (in square meters) , you get a rough estimate of your PPFD. Now the problem is that to calculate the radiant watts I need to kmow if the led is 50%, or 45%, or 60%...

Thanks, I will try to scrog it

Damn, now I am scared. I guess I can always disconnect strip if I need to dim more. Thanks.

I did the math and I can only dim mi lights to about 80watts and my space is 3.5 square feet. Think 80w will be too much?

The reason why people wire lights in parallel is because lower voltage is safer, and I think it is also easier to troubleshoot. I am not 100% sure how CV+CC drivers work since I am waiting for my order to arrive to build my very first light, but I have read a lot about it, so I'll try to explain...

I guess most people know this but I am still posting it for those that don't know (I found out yesyerday) I ordeedr some 560mm gen 1 strips and a hlg-185h-24a to run these in parallel. For gen 1, you can use either 24v driver (to run strips at 700ma or more) or 20v driver (to run the strips at...

Thak you, great explanation from cobkits.

I thought that since it is a CV driver, all I could do is adjust the voltage and then the led would pull what ever current is associated to that voltage. For example if I adjust the voltage to 22.1v, then the led would only pull 700ma, if I adjust the voltage to 22.7v, then the led will pull...
