LED PL Retrofit Lamps are designed to replace inefficient compact fluorescent lamps (CFLs) with easy installation. Available in E26, GU24, GX23 and G24q base options, the lamps deliver uniform consistency, and a long, 50,000-hour life. The lamps, which replace 13- and 18-watt CFLs, retrofit a variety of commercial fixtures, including recessed cans, sconces, and ceiling fixtures commonly used to light retail stores, hotels and apartment buildings. Constructed with a lamp holder that rotates 270 degrees, LED PL Retrofits feature a simple ballast bypass to ensure maintenance-free, energy-saving operation and higher performance, as well as instant-on capabilities. The lamps are backed by a five-year, limited warranty.
