I bought my 220g (72"x24"x30") tank secondhand, and it came with a light (specifically, a Fluval aquasky), but the previous owner of the tank must not have had live plants, because the light is proving dreadfully insufficient. So, I'm looking to buy some better lights. I've done a bit of research, and I'm sort of interested in LED floodlights. I'm looking for advice regarding choosing a specific model, and/or suggestions of models that people have had positive experiences with. Or, alternately, if anyone reading this thinks LED floodlights would be a poor choice for my tank, suggestions of what lighting type you think would be a better choice.
