I've got a 60cm T5 fixture currently residing in the garage, details http://bio-pur.de/bright.htm , currently with 4x24w T5 10000K tubes in. Never used. I was considering putting this onto my ~80L 60cm scape.
hey mate, i didn't take the decision 'lightly' to shell out for a LED system. Just remember that if you get Led's you cannot change the K rating, as you can with the bulbs. I just saw that you have 10000k bulbs, that must look a little marine like. I love my new unit and can say that i won't be going back to tubes...also be aware of the cheaper units from china aren't very good.
