How about a High Bay T5HO 4 Lamp Fluorescent lighting fixture that sells on Ebay for $115? I've read a bit about T5HO lights and some people really like them for aquariums. Would this provide enough light for the plants in my 55 gallon tank? And what type of bulbs? Can I buy regular bulbs from Lowe's or do they need to be "aquarium specific" bulbs?
