Nothing is really to bright. Just proper acclimatization is needed.
All this to bright for certain corals now. Bah. In the mid to late ,90s I grew tons of various soft corals and lps corals under my 250w 65K Iwasaki. Not much brighter than those.
Just manage depth and/or lighting periods when changing bulbs or adding new corals, until they are use to the lights. The eggcrate with some window screen also works well for acclimatizing.
You can keep corals that require less light down on or near the bottom, with proper lighting, instead of trying to get everything up into the light.
