Here is what my setup looks like.
I use a 5 gallon bucket for the heater but any size container will work as long as you can submerge the whole heater in water. I am thinking about using a smaller container so I have more room in the tank. My lights are very expensive. Think I paid around $1000.00 for them a 5 years ago when I had my salt water tank set up. They are specifically designed for coral growth. 6 96watt HO compact florescent bulbs. It's hard to see but the one bulb only puts out a blue 440-490 nm color to promote growth.
These bulbs are long overdue to be replaced and should be replaced every year but I have not done it in a couple years. At $29-$40 a bulb I'm not looking forward to the expense especially since everything is growing so well now!
If you are looking for new light fixtures try aquarium stores and such. I used a place called ThatFishPlace.com and they have great prices on all sorts of lighting from 15 watt light bulbs to 1000 watt metal halide and very good pricing.
