Rex, going to disagree a bit.
Shoplights are fine for those on a budget, or who just want to get their green thumb wet.
On my 45 gallon tank I have one shop light. It even hangs over the edge 4 inches. I know I'm not getting that much light in there but I have Crypts, Vals, Sag, Hygro, and Java fern in there. Everything does great. OK, they hygro is kind of leggy, but thats it. The sag and vals nearly take over everything if I let them.
I have no plans to upgrade anything on this tank. Sometimes I like it better than my high tech tanks because I don't have to constantly trim stuff.
For people who don't have the cha-ching that some of us have, they do great. Like 20 bucks at the hardware store.
I started out this way, because the whole high-tech planted tank intimidated me badly.
I reccomend this to folks with a good amount of fish exp., but no/very little with plants.
