Reefbreeders Fixture upgrade? Worth it? Spectrum?

First I really like my Reefbreeders unit...so I wanted to ask if this is worth doing at all?



After looking at some really beautiful tanks, I have noticed that a lot of them have some high kelvin rated bulbs or LED's, but after looking at the value led layout, channel 2 is mostly 4500k neutral whites. Shouldn't upgrading them to a mix of 10-20k LED's improve growth and visual appearance?



I see that Reefbreeders DOES offer a wide variety of blues (420nm-660nm) and whites (3.5k-20k):

Is it worth upgrading some of the lower kelvin LED's?

My goal is a mostly SPS dominated Reef.



What are your guys' thoughts on this? Any opinions or suggestions?

Should I consider it, or just leave the fixture alone?


(I don't have much soldering experience. A little, but not much. I soldered some wires to install my headunit in the car...that's about all I have.)



Here is the default layout on the Reefbreeders Value LED Fixture.







"There are 2 different dimming channels, controlled by knobs on top of the fixture. Channel 1 consists of 13 4500K neutral whites, 6 480nm blue, 6 420nm violet, and 2 660nm deep reds. Channel 2 consists of 28 450nm royal blues, for a 14k output with both channels at maximum intensity."
