I'm interested in the AquaEl Ultrascape 90 which comes complete with lights and cabinet. Unfortunately the lights (AquaEl Leddy tube lighting 2x14W Plant and 2x14W Sunny) don't appear to come with any kind of dimming option other than raising them with the supplied light stand. The lack of a dimmable light with what otherwise seems like a pretty good set-up looks like a showstopper. Does anybody have experience of the product or thoughts on this apparently non-dimmable 56W light set-up?
