In your opinion would it be better to step up to 50 volt or is 36 just fine for what I want to do?

I have questions that I have not found answers to yet :) ok cool got that sorted out now how bout those cone reflectors do you need them? Should you use them? I will deal with heat passively.

Cool that's what I was looking for thanks

Well have not gotten that far yet was just looking for ideas.

is it better to run at a higher voltage and lower amperage?

after you mount your cob to your passive heat sink how do you mount that assyimbly to your frame work?

im looking at it if someone has info or an opinion let's hear it.

How many watts a sq foot for veg with cobs?

I think keeping it at a. 2x4 spread I would have higher intensity light may just go to. 12x10 or 12 for final goal but at the moment I just need some where to start all this info is cool but I don't learn that way so I need stuff to work with.

ok so running in parallel is going to be my best bet for what I want to do. Running in parallel like above will the 1212 chip put out enough light intensity at 44 watt?

What are the pros and cons for wiring in parallel vs searies.

I just looked at a 185h c700 286 volt looks like it will run eight but with only 700ma but that is soposed to be the best way to run them to get the most photons vs heat right?

There's would not be enough voltage right there only 143 volts output? Maybe I'm looking at the wrong numbers

Would it make that much difference?

You would have to wire in parallel correct?

Well that's not going to work I don't think

So I think I want to do a light that will cover a 8f2 area from what I have read I think that 8 citizen 1212 3000k 90cri can be driven safely with a hlg 320h 36a am I right or am I wrong?

the end goal is to be able to cover 100f2 but want to start small and just make a bunch of individual lights to be able to adjust height where ever and when ever needed. Clear as mud lol I like the looks of the citizen 1212 but have not figured out the most efficient way to drive them any one...

3000k work as good as 3500k?

Thank you all so much this is great info
