I have a few smaller aquariums that are older and require these type of lights. You can usually find them at most Pet stores and even at WalMart for a very reasonable price.
They seem to last quite a long time before I have to replace them,and they must be pretty good as I have Amazon Plants that I grow in my Kuhli Tank,that have always grown very well.
They come in other colors rather than the clear,but I tend to stick with the regular.

Pros: good price can find pretty easy seem to last long

Cons: none

This is a good basic bulb for your incandescent lights. Work well, puts out good light, lasts quite a while and they're extremely economical. I've been using these for years.

Pros: A decent bulb for your incandescent lights.

Cons: Non found.

I always liked this plain low-wattage incandescent bulb to enhance my aquariums. It lasts a surprisingly long time. I rarely needed to use a tank heater, thanks to the bulb's heat -- but do check your tank's thermometer regularly.

Pros: Inexpensive source of light and heat

Cons: Keep water level safely below bulb

These bulbs do work well. They do last while. And inexpensive.

Pros: works great

Cons: none

This bulb does the job. It's fine

Pros: okay

Cons: none
