Good evening everyone. Does anyone know the color temp range of the Kessil H380? I have a Hydra Prime over my sump and I’m wanting to match the Kessil H380 color for increased growth.
Thanks in advance for the help!!

It's not a temperature in the way that you're thinking about it. It's simply red (660nm) and deep blue (440nm) leds that create a purple light.
Chlorophyll A and B pretty much utilize just those parts of the spectrum. It's the reason plants are green. They don't need the green part of white light, so they reflect it.
Also, you'll find that red leds typically outnumber the blues in grow fixtures because the blue spectrum is utilized more efficiently than the red, so a little goes a lot farther.
As far as adapting your light to replicate the Kessel, you can target the same spectrum, but you aren't going to be able to duplicate the intensity considering that you only have one red led, and a handful of blues. Just crank your light as bright as it can go and that should help. Chlorophyll will absorb what parts of the spectrum it needs and pass on the rest.
