ok dont laugh, this may be a stupid question... can i buy big flourescent lights from lowes? they are like 65 bucks for a 8 foot light versus 300 or more for an "aquarium" light. advantages? disadvantages? I found i can get just about all the same light spectrums at lowes and even if they dont last as long, at 1/5th the cost, would they make more sense? I dont really have many live plants and my fish dont need high intensity lights, but i am working on a budget. Thanks
