Thank youBonjour
B version need a potentiometer (100k) between dim+ and dim- wires.So B it is! But the A version have one inside to dim from 50% to 100%

take its temperatureSo I got my lights hooked up and working, 2 heat sinks 5.88" x 19" with 2 cobs on each(3590 3500k 36v) being run by HLG-185H-C1400.
My question is how hot should the heatsinks be? I touched for a few seconds and they are really hot, just wondering what I should be observing if any thing.
Nope that certainly won't do.Ok so I'm planning a diy light. Got 3 cxb3070 3000k in my basket and wanted to know which driver I should buy to power them. http://uk.rs-online.com/web/p/led-drivers/7736961/
Is that sufficient??
Ìt's up to you how much power you supply them. Less power = better efficiency.Tbh I don't know that much about them. I was hoping the 3 cobs would be enough if I made them individually. Which driver would you recommend . Hoping to pull about 200w? If I have been reading right the leds are 100w each
I see. I think it would be best to get 4th 3070 and go with Meanwell HLG-185H-C1400.Have a 0.75x0.75x1.8m tent if that helps. Was thinking of making 3 individual square fixtures. Cooling Fan and heat sink for each light then
So I will only need the one driver?
Would I be better making 4 individual cobs or 1 large square fixture?
Also which letter should follow that driver c1400*
Looking at this one
Dimmable Constant Current LED Driver 151.2W 71 → 143V 1.4A Mean Well HLG-185H-C1400B
Yeah you'd need only one driver. It can work with (3) CXB3070 as well but your space deserves the 4th one.So I will only need the one driver?

They are. But I don't think that square tubes are solution to that.Thanks man. Heatsinks are expensive lol. Thinking of using an aluminium square tube

If I get the 30cm long and have a cob at each end with a cooling fan mounted at each end using a kinda push pull for airflow. Thoughts? Or maybe mounting fans on top of tube. Cutting a hole and mounting a small heatsink on inside of tube so heat will spread through tube onto heatsink then be cooled by fans blowing in on top?
@EfficientWatt didn't even see that post lol should have looked more. Lots of info to go through so I may miss a few details.
from what I gather so far, the hlg-185-c1400B is your best driver, the B means you can add the dimmer (100K potentiameter).Thanks man. Heatsinks are expensive lol. Thinking of using an aluminium square tube

Is there a specific temperature range for them to ideally fall in? I need to buy a thermometer.take its temperature
Isn't this too much even for V29?Just looking, but was thinking of running some V-2 29's hard
on some tall plants. Back to bean search.
My day was great, now after midnight here in the land of sticks.

I dropped my $ on beans, but I was checking to see if they had them in stock and the cost. At theIsn't this too much even for V29?
