I want to do LED lights on my new 100 gallon FOWLR tank. It is 60x18x20 deep. I have a couple of questions. 1. Knowing that I just need decent light and that I am not trying to grow anything, what would you recommend as far as the number of lights. I have never seen these LED's in action and have no idea how bright they are. 2. Since I am doing a FOWLR and want more coverage than penetration, I was thinking of getting a kit with the 80 degree lenses. My question is do you make an 80 degree lens for the XP-G LEDs. I didn't see them on the site. Or do I even need a lens? This might sound crazy but I am having way more trouble deciding on lights for my FOWLR than I ever did with my reefs. Thanks in advance for any help. LEDs are new to me and confusing me.
