if you've been eyeballing commercial LED reef lights but haven't yet found one that suits your particular need then consider the hefty DIY kits offered by Reef LED Lights. The fixtures that RLL provides through their kits and and in completed form are the epitome of no frills, but for that you also get a light that runs at the power you want, in the color you want, and with or without your lenses of choice. Reef LED lights gives you options of doing a simple strip, a value Cree XR LED model and a rocking Cree XP LED setup. The actively cooled LED setups may not be much to look at but with great LEDs running at optimal temperatures and using good optics you ought to really be able to build a decent metal halide replacement.
