I got the 18" for my 10Gallon to start the cycling of the tank until my led kit arrives. To my surprise it gives off a very nice cool blue look. almost equal to my t5HO fixture on my bigger tank.
I would recommend this to a friend!

I had to return these items to a PETCO store. When I ordered them, the description never mentioned they were aetenic bulbs. I needed a much brighter light. The store exchanged them for new ones, at the same online price.
