any ideas for a low light 90g

[DEAD_BY_DAWN]

after doing some priceing for lighting for my 90g then looking in my wallet only to find a four month old safeway reciept,i was kicking around the idea of going for a low light reeftank say two 10ks and two actinics, seeing the colours on some of the deepwater corals and sponges,i thought there must be a reason why not alot of people have them in there tanks,if any one wants to post some ideas or sites that might help out please do so thanks ...john
whats in the tank right now is
2"-3"ls and 60lbs of lr one naso tang a snowflake eel,and a green birdmouth wrasse,
