Cant really tell you a site since its not allowed to post competitors sites, but they new clip on 50, or 75 watt Metal Halides are nice ( i think the brand is Sunpaq)
Some easy to care for corals are:zoas, leathers, mushrooms, ricordea, brains, frogspawn, torchs, (most soft coral and some LPS are pretty easy to care for)
