A Switch to T5 might help in the long run but no quick fix. A combination of LED and T5 is probably the best bet.
I wanted to add my comments based on the last couple of pages. I will respectfully disagree with some points others have made, but that doesn't make me right and them wrong.
LUX is centered around what our eyes are most sensitive too, which is green. If you had a T5 fixture, for example, and replaced a blue+ bulb with an AquaBlue special the LUX would rise dramatically because the ABS has a big peak in green light. LUX is higher, it looks brighter, but as far as the corals are concerned PAR is close to the same (ABS is higher par due to more red in the spectrum). All that said, I do thing LUX meters can be used to judge changes your eyes might not detect, just understand some changes might not register. Increasing blue while decreasing white would show a drop in LUX, for example. while PAR would probably increase.
One of the things I don't like about most LED fixtures is how much PAR they can put in a tank and still look dim to our eyes. This is why most folks fry corals with LED. Not a thing wrong with LED, and dialed in the results can be amazing, but hard to dial in.
As far as color, the Ponape bird and orange digitata are showing signs of too much light. The ponape is an odd ball because it actually prefers lower light to look really good. Turning down the whites may help. Other than that I would say coral chice is the main issue with color. I have a lot of unnamed acros in my tank from random LFS frags and all have drab colors. Acros I purchased with known good coloration might not be as colorful as I want but they are light years ahead of these random frags. IN MY OPINION.
My tank for reference. 160 gallon 6 footer, MP40's on either side and two RW-15's in back to help reduce the center dead area, which is not that dead but then I only have 18" front to back.
My colors look best when I dose nitrates to keep them around 5.
