Plug-in CFL light bulbs are an efficient and longer lasting alternative to incandescents. Available in twin-tube, quad-tube, and spiral shapes, these lamps can only be used with electronic ballasts specially designed for 4-pin lamps. Plug-in CFLs come in several color temperatures ranging from 2700 Kelvin, which produces a warm light similar to incandescents, to a full spectrum 6500 Kelvin that simulates daylight. Capable of withstanding high temperatures and enclosed applications, plug-in CFLs are commonly used wide range of applications including warehouse lighting, retail displays, and downlights.
