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.

Before buying, double check to see what socket your fixture uses to ensure you purchase the correct bulb. Plug-in CFLs are not interchangeable and require a specific socket. Change out old sockets with replacement plug-in CFL sockets. If you are looking for additional energy savings, plug-in CFL LED replacement bulbs are available.
