Item # 209914 / Manufacturer Part # 05635
Coralife 6700K T5 fluorescent lamps contain trichromatic phosphors that provide a natural white glow over your aquarium. Ideal for freshwater aquariums with live plants, the full spectrum bulb replicates natural sunlight and stimulates lush growth and photosynthesis.
Efficient T5 lamps provide as much or more light than comparable T8/T10/T12 style lamps, while using less wattage and saving on energy costs.
Designed for the 30 in. Aqualight T5 and other compatible fixtures, the 18 watt bulb measures 27.625 in. long. Not compatible with T8/T10/T12 style fixtures.

I got a new bulb in January and by the end of February it was burned out. Thinking about getting a completely different light fixture. The blue actinic lights seem to be holding up ok, though.
Terrible bulbs 7/2/2012
I ordered two of these in May. By the first of June, one was burned out and the store sent me a free one. Now it's July 1 and the other is burned out. Coralife is just not what it used to be either in fixtures or bulbs. Save your money.
