LEDgardener

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 10-3000k and 10-4000k. But saw somewhere that Teknik said 4000k are best, why is this?

I would wire these 10 parallel x 2. And take the 2 sets of 10 and wire them in series.

Would this wiring work? 10 parallel together would give 1A at each strip. The 2 10 strips wired in series would give a voltage of double which is in the driver range, but given that the max voltage of one strip is 21.6v which is less than the driver min, would this be too much. Obviously I'm not clear about this.

I mentioned 4K for a mother plant.

4K keeps things more compact than 3K, you don't want to cause your mother plant to run out of room if you are keeping it for a long time

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. Also the 4k diodes are the most efficient.

For flower do you think 4k would be viable, or would it be lacking compared to the 3k?

There is a big difference between 4K cri80 and 4K cri90. For flowering more red is better.
