You can do a diy led kit which isnt hard to build at all.
http://www.aquastyleonline.com/produ...mable-Kit.html thats the kit id recomend and is plenty of light for sps. You can always get a smaller kit and then order the different color leds extra if you want a broader spectrum which is what I did. I went with the 36 led kit (they sent me 40) 20 white/20 royal blue then I also added 20 regular blue. Seems thsts the combo most high end lights run these days. You could get red, green, yellow etc but corals dont really use much of it and there's also a lot of debate about those colours whether they benefit you or your algae lol You must get dimmable or you will cook everything. I cooked a mushroom on the sandbed when I first got it.
My tank is a little bigger than yours and im running 60 leds and I can cook sps if I dont turn the intensity down.
