I have the 304+ boards from meijiu in my tent. I just ordered the single heatsinks from meijiu with my order.I was talking about the folite 304 led boards with 1oz copper with 286*174*1.6mm dimensions or the folux 288 on the same board size and thickness I believe. Which of these boards is the better board anyway? I am assuming the 288's thanks to lower voltage having more PSU options making them more flexible.
I figured mounted in some alu L frames I could run them at half power, 4 boards on a HLG240. Anyone with first hand experience? Of course I can always run fans on them and the area they will be in is ventilated, plus these things can take more heat than we allow them to get to be on the safe side. I mean its great to have them running at 35c but they are still just fine at 55c as far as I know.
Am I still being realistic or should I be looking at the LM301 boards for better thermals (is this even true? Its in the QB sales pitch), looking at mounting on 4mm alu plate instead of L frames, or go for 6 boards per HLG240. (or even go for fotop 800 instead, my least preferred option)
I am trying to be energy and heat efficient, while also being price efficient and at all times keeping safety in mind.
As for safety, if one of my 4 boards for whatever reason craps out, does that bring the other 3 boards up to 80 watts each, making 6 boards a safer option or is this safety concern negligible?
Edit: I'll likely go the HLG heatsink route (4mm 660*490 alu for about 20 eur excl VAT each) and run them 60w but am still curious about real world results without heatsink. Hope Rita is working Sunday
Driven at 50% the heatsinks get hot enough thats its uncomfortable to hold you hand on them.
and if u wire them parallel thats exactly what will happen. its also how I have mine setup. I have 4 sets of 4 boards in parallel each set on its own driver. I wouldnt go any smaller than a 320w driver per set of 4 304s though.
