I couldn't figure them out, shadow, spectrum and growth. I just gave up as messing with them was a bit frustrating for me.
They are nice lights though.
I'm giving LEDs one more shot with the hydra.
There's nothing I love more than the look of 20k Radiums using VHOs for supplemental lighting. Just can't get that shimmer look using LEDs, not on any tank I've ever seen.
I also haven't found a T5 actinic bulb that compares to VHO 454 or Super Actinic.
