I startd this thread because I really dont know what are the advantages of t5 over power compacts. I am about to buy the jebo 24" 2006 editoin for my 30 gallon tank but because everyone seems to be talking about t5s in this forum, I jsut want to ask what really is best. Also, What do you think about this jebo 24" high compact aquarium lighting. The one im looking at is the 130 watts total output from two bulbs. Does anyone have experience with this?
