Dude i swear to god i cant understand it at all. Usually intensity is tied to colors for example u put 50% intensity, it drops all your colors to 50%. What in the world is schedule intensity. Brightness? Or is it referring to my 50% ramp up at 8:00 AM.
As far as I understand it, it's for PAR. So if you get a PAR meter, you can easily make more detailed tweaks to your schedule, and it will adjust the ramp. Since they are great lights, 100% might be too intense for corals used to lower PAR.
For example, you have it at 50% at 7 am, and 100% by 8 am. Let's say you are getting 2x the amount of PAR you need, and corals are bleaching. If you were to turn the "schedule intensity" to 50%, it would ramp BOTH down by 50%. So that would be 25% at 7 AM, and 50% at 8 AM. This way, you aren't having to tweak each individually (like I do) and do the math (like I do, lol), and you can more easily tune down/up the lighting without overly stressing the corals. Yes, it does tune up and down the colors at the same rate. So if you have like 20% white light, say 100% of everything else at 8 AM, and turn the whole schedule down by 50%, it would turn the white to 10%, and the rest to 50%.
You probably don't want to make significant adjustments, I just used it cause 50% is easy math on me, but yeah, it takes the math off of you of multiplying percentages together for everything.
If I were to get a new light, it would be this one, cause this is way easier than adjusting EACH color by the correct % at each of my time stamps .
