Plug in lamps provide even light distribution and stay brighter longer with an average life of 8,000 hours. They are ideal for interior lighting. Operating temperatures: -10°C / 14°F to 70°C / 158°F. Non-Integrated Lamps have the ballast permanently installed in the fixture; therefore they themselves are not equipped with a ballast. 4-Pin models, which have no internal starter, are to be used with electronic ballasts.

Compact fluorescent lamps (CFL) provide the same amount of light (lumens) as regular incandescent lamps but have a lower wattage rating. This means they use less energy and cause less pollution.
