I'm interested in making my own LED
setup for my tank. I have a 30 gal
tank (36" long) I already have corals, even one sps
. I want to make something that will support all corals. I'm having trouble finding where to buy the lights! I've found the bulbs that screw into a regular socket...if I were to use those how many would I need on my tank? They are over $100 each! I've seen people use the small bulbs (1watt or 3 watt) and arrange them into a lighting setup....where do you buy them?
