No racks yet, but my poor ass just got the cheapest 4' led shop light I could find (some things at wal-mart are still cheap), for cheaper than it would be to get a new bulb for the old florecent light I was using. Much brighter and better color now. Anyway, the lights are link-able and I have an old weird 50 gal I could get running again, think I'm going to go that route myself.
