General lighting for thousands of LPS

[uwiik]

I've seen scolymia, trachy, cynarina, euphyllias expand beautifully under 250W and I've seen it bleached and died under 150W, and I've seen it expand and coloring up like crazy under indirect natural tropical sunlight with additional blue pp shade on top, it is very dark and blue, yet they expand and coloring up nicely.... So what is the safe general lighting for LPS?? I am holding thousands of em, so It is impossible for me to meet each individual corals need. I just need the color to stay and thats it.... Currently I use insulated roof with patches of clear pp, clear area is about 35% of the roof, bear in mind that this is tropical sun we are talking about. Is 35% clear scattered patches enough for general LPS? Corals are positioned 10-20 cm under water surface, water quality is top notch suffice to grow SPS.
