on color temperature

I'm hoping to build a single or double cob led light and I see they are usually 3000 k. Why aren't they mixing a 5500k with maybe a 2700 k. Plus I don't understand why a 3000k COB shows a full color spectrum from 380 nm to 730 nm. If I were using fluorescent bulbs it would be 6500 k and 2700 k to spread out that spectrum. Confused

Just build a light with Vesta strips. They're 1 row 2700K and the other row 5000K..

They're 24v too.

That's for each channel.
So a 48V driver that can be used for tons of other stuff too is what you'd use. You'd just run the two different channels in series, or run 2 strips next to each others individuals channels together. 2 2700K in series and same with 5000K.
Also, theyvhave tested them at 2000MA per channel for temperature data. So I'd think with decent heatsinking, 15-1700MA would be fine. That'd be 65-80watts a strip.

Am I correct in this @Rocket Soul

I read an article about Green Light being absorbed at 90 to 95 % and how Far Red benefits bloom
Also, they talked about 5000K, 4000K, and 3000K COBs, I was wondering what you all thought, because I'm not seeing this combo in discussions? I only hear about the 3500K

Forget it I'm just going to HLG
