These T-5 Fluorescent from Coralife looks very interesting. I'm thinking of upgrading my dual tube T-12 to T-5 bulbs due to much better efficiency (less heat, more light). Obviously, these aren't designed for 3watt+/gallon aquariums, but for low light aquariums... The price is good too. I wonder about the quality of these things though.
