Compact Fluorescent Lamps

Hey, has anyone used compact fluorescent bulbs for small planted aquarium? Like the ones shown here:

They connect like a regular incandescent bulb, but have a higher out-put w/ less engergy used (compared to incandescents). Do you think one of these could be used on a small 3-gal tank for plant growth? I mean

I was thinking of setting up a small (I think its 3 gallons) cube shaped glass tank. With plantings ect. Could I use one of these bulbs with a reg. desktop lamp? I mean 12w for 3 gallons is 4w per gallon!

Watts per gallon is a poor indicator of light for a small tank. Read Rex's guide, it will answer most of your questions. A lot of people here are using the Lights of America daylight PC lamp for their small tanks.

In no aquariums for a while.....

the answer is YES. You can use thoes lights. The ballast is attached to the bulb. I use a couple of 25 watt ones on my tank. Make sure you buy the ones that come in the right light spectrum spectrum. I think mine are 6500k, but you can get ones that go up to 10,000k.

Buy a couple of desk lamps, and you'll have pleanty of cheap lighting. You dont have to buy the bulbs online either. Almost any hardware or home improvment store will carry the same product. There are meny diffrent brands.

75 gallon, fillstar xp2 with inline reactor, 12 Lb pressurised co2, 4.2 WPG-corallife 3x96 watt PC-, fluorite/silica-sand substright.

i use a 25-watt compact flourescent in my small tank.. actually, compact flourescents are much brighter than flourescents with magnetic ballasts of the same wattage.
