CFL 24W - 4pin - 2G11 Base
24 Watt 2G11 Base Compact Fluorescent (CFL) Plug In Style 4 pin light bulbs are one of the most commonly used energy efficient lamps on the market. This type of compact fluorescent 4-pin requires a separate ballast to operate the lamp which is typically located in the lighting fixture. If you put in a new light bulb and your fixture still doesn't work then your ballast could be out.
