I think I have the best solution for the lights but I need some help with admittedly basic information that I don't have. I have a lighting engineer who is part of my project team for the house. He has been talking to the Philips lighting engineers. They have been asking questions that I don't have the answers to, so I thought I might ask them here. The solution that I am looking at has the following characteristics:
ColorReach Powercore (housing)
Each fully aimable panel is ( H X W X D inches) 20.5 X 28.9 X 4.8 .
Each panel has two parts split evenly into ..........
Lumens 5200+ for the RGB LED
Lumens 1777 for the white light at 6500K
The RGB can throw light 500 ft.
There is no PAR information so I bought a single fixture to test with.
I will eventually get six panels. This lighting is capable of infinite dimming while maintaining colour temperature or varing colour temperature while maintaining brightness levels.
Beam angles 8 / 13 / 23 / 40 / 63 deg. 5 / 17 deg asymmetric lens.
designed for dry, damp, wet locations.
Questions are............
1. What is the impact if these lights do NOT offer light in the UV or IR frequency range?
I will have managed UV light in the fish room as part of the CL system.
2. Is the PAR measurement the only relevant measurement as far as coral health is concerned?
3. What differences in light requirements are there for fish vs corals? I realize fish can move and corals can't, for the most part.
Any feedback from knowledgable sources will be greatly appreciated.

As most of your questions were answered by Mr. Wilson, you probably should try for 63 degree optics as this would give you the best spread for you tank and since its shallow, you don't really need the focused light that say a 23 degree optic would produce. There are many DIY LED thread out there right now. All of the ones Ive read have all found that the 60 degree optics are best suited for the application at hand.
Here is a good thread
