Oh, I see. Yeah, my calculations are that I'll be running these at about 300w for 10 4ft strips so I think i'm in a good range. The other bonus to using more strips is higher efficiency Sorry for all the questions, I know I have a lot. :D But what do you mean by that? If I use more strips per driver...

I don't have much knowledge on the subject, but I've been studying my ass off for the past several days. I've been reading some good university level studies, some I'm barely comprehending. :) there are many variables at play in these studies, and at the end of the day the jury is still out, but the...

2ft strips can handle 15 watts, better to buy more strips. Its really not worth using heatsinks considering the price of bridgelux strips. All the FR4 boards can handle 15 watts per 2ft. Aluminium pcbs like Cutters can handle 25W without heatsinks over 2ft. The other bonus to using more strips is h...

Thanks Ganjah, sounds like a plan.

Putting together 2 x 10 led EB gen 3 lights. Total shipped for the led strips is $200. 1" heatsinks cost $252 at heatsink usa. Damn, that is a hard pill for me to swallow. Does anyone know of cheaper options? The EB datasheet intro said heatsink may not be required at lower driver currents. Now, I'm...

4000k or 2700k? These are the two I can buy right now in 90cri. Can you tell me where these are available. I've been interested in these Gen 3 90 CRI and have found no one that sells them outside of a special quantity order. The graph on these shows a significant increase in spectrum but at a signi...

In looking at the Gen 3 80 CRI graph, the 4000k looks like a really full specrum. The range of blue is wider and deeper, though I realize that is less significant for flower stage. But the difference in the red range is minimal between 4k and 3k. It seems like only about a 5nm less of the red range....

I am building a light essentially for a 4x4 area. The strips are EB gen 3 - quantity = 20 x 2ft strips. Typical voltage 19.1v, min and max - 17.8v - 21.6v. Nominal current .7A - max 1.4A. Driver = HLG-480H-48B - Output current 10A (max), Output voltage 24v - 48v, 480 watts. I was planning on using 1...

4000K strips if you can get them.

Not meaning to hyjack this thread but curious why you like the 4000K?

Hey Falcon, don't feel bad, they are still good grow lights, and you'll find a use for them. And they were only $75. I bought some crappy Amazon blurple LED lights for about that price and they are shit compared to your Samsung full-spectrum.
