Bridgelux EB Gen 3 (3'x3') - First Time Build

Hello all, I am totally new to the Led DIY world. II was going to follow the original LED strip builder guide and found the 3x3 set up in the section, but seen they where designed for gen 2 strips. Now i plan to use the 2' strips with all 3000k. I just dont know if (15) BXEB-L0590U-30E1500-C-C3 will till work with the HLG-320H-20B Driver wired in parallel. Please, someone confirm.

Check out the post I just made about an EB gen 3 4x4 build to give you an idea on driver pairing. My best recommendation would be to develop an understanding about the LED strips you are using and the drivers you want to pair them with, there are countless resources on this site. This video series was by far the most helpful for me regarding both wiring and driver pairing:

The current vs forward voltage performance curves on the EB gen 3 data sheet is what you are interested in. To help get you started, it looks like 15 strips wired in parallel to that driver will pull about 1A each when operating in constant current mode, resulting in a forward voltage of around 19.5V on the strips. The constant current region for that driver is 10-20V and keep in mind the B type drivers do not have a voltage adjustment dial.

Hey man. Thanks for the input. I've now increased the size of my space to 4x4. The information you provided helped a lot in the basic understanding of wiring and drivers. Now its time to pick out the color. i have an old blurple and was going to use that as my veg light, then transfer to this new setup when its time for bloom. I would start at 50% power at first, the work my way up as they adjust to the intensity. Or you think there is a way to have a full cycle light? Defiantly open to the concept of full cycle.

I would consider a full cycle light 3500k, but that's just what works for me and my growing habits. The recent build I did for a veg tent uses 3500k because I have better results in veg with that spectrum then 4000-7000k.

Chilled Logic 660s are considered full spectrum and have a mix of 3000k, 5000k and 660nm diodes. Results have been insane.

Absolutely nothing wrong with a dedicated flower light neither. Check out Tekniks post about 2700k 90CRI Bridgelux EB gen3s because the results are very promising.
