I breed angels in most of the 23 tanks I have. I use several single brights. They are cheap and easy to move from tank to tank as I need. But I also keep potted plants and dish gardens in just about every tank; even the barebottom tanks. The SB's do fine with the basic java, crypts and anubias. If you use the mounting legs they come with, the coverage isn't the best. I don't know what angle the optics are, but you need to raise them off the tank a bit to get better coverage. Absolutely not the brightest things you'll find, but they don't break the bank and may fit certain situations OK.
