Coralife 10,000K Daylight HO T5 Fluorescent Lamps 30" 31W
These are the lights that come with the Coralife T5 light fixture. I have had this light for almost a year now and I have to say that I am very pleased with these bulbs. They provide a nice crisp white light and my corals and fish seem to enjoy it. They aren't so bright that any of the corals burn and I can keep just about anything in my tank, except for the clams that require the intense lighting, but then again I have never tried. So far I haven't had to replace any but probably will in about 3 or 4 months as a routine maintenance. Great lights

Defective at first, exchanged and now working well
I purchased these bulbs and got a defective bulb that caused my light to trip my gfi plug. I returned it for an exchange and got it about 2 weeks later with no issues. The bulb itself works well and along with my actinics (quad fixture) is allowing my corals to grow nicely. The only regret is that I purchased the 30" fixture which is a non standard length so I can't buy bulbs from other manufacturers.

Not worth it
I have had to send this light back once and had to have another sent to me. They lasted only 2 weeks, at which time I noticed the brightness getting dimmer and dimmer. I switched out bulbs to make sure it was not the ballast. I would recommend spendning a few extra dollars on a brand that will last.
