About CFL Bulbs - Compact Fluorescent Light BulbsElectric lighting consumes up to 25% of the average home energy budget. The electricity used over the lifetime of a single incandescent bulb costs 5 to 10 times the original purchase price of a cfl bulb or compact fluorescent light bulb. CFL light bulbs are simply miniature versions of full-sized fluorescents. They screw into standard lamp sockets, and give off light that looks just like the common incandescent bulbs - not like the fluorescent lighting we associate with factories and schools.
CFL bulb styles
Spiral LampsContinuous tube in a spiral shape which has similar outside shape and light casting qualities to a standard incandescent light bulbs. Spiral CFL bulbs are made in several sizes to fit most common fixtures.
Standard LampsCFL spiral lamps with a dome cover. Designed to give the appearance of the traditional light bulb. Glass diffuser provides a quality of light similar to the 'soft-white' type of incandescent bulbs.
Globe LampsCommonly used in vanity mirrors or open bulb applications. Vanities usually require multiple bulbs, which generate radiant heat. CFLs reduce this heat buildup and save energy. Diffuser provides a soft-white light.
CandelabraScrew-in torpedo-shape and small-base of this bulb is designed for smaller light fixtures from chandeliers to sconces. To use a smaller candelabra-based bulb in a regular socket, you can use a socket reducer.
Triple Tube LampsThese CFLs have more tubing in a smaller area, which generates even more light in a shorter bulb. They pack high light output into a very small space and can be used in fixtures designed for incandescent bulbs.
Flood LampsDesigned to be ideal for recessed and track lighting fixtures indoors and outdoors. They provide diffused, soft, white light, and generate less heat than will an incandescent flood or a halogen bulb.
CFL base styles
Plug-in baseSmall plastic bases with two or four pins and are designed to be used with separate ballasts which are mounted in the fixture.
Screw-in baseStandard Edison-style base such as those found on incandescent light bulbs.
GU24Designed to replace the Edison socket and base to match the newest Energy Star requirements. GU24 fixtures avoid backward compatibility with screw base bulbs which guarantees higher energy efficiency.
