Terry, you can ramp them up however you want, but I'd recommend dialing down their intensity and gradually increasing it over time so your corals can acclimate.
I started mine with the following program:
On at 930am with a ramp up of 120 minutes. Initial intensity with white at 20, blue at 30 and royal blue at 25. Then off at 11pm with a ramp down of 120 minutes starting at 9 pm.
Moon lights with royal blue at 1% over night.
Over time I've increased the intensity. Now I have white at 30%, blue at 40%, and royal blue 35%.
That's the cool thing about them, you can fine tune them for whatever you think looks good. Like I said though, I recommend starting low and going slow. I should also say I run mine primarily for supplemental lighting to my halides. If they are your only lighting, you might not want them as blue as I run mine.
Did you get them? Or are you just thinking about it?
How many did you get?
