The Keystone KT-LED94P-H-840-S is a 9-watt LED PL lamp designed to replace traditional CFL downlight and wall fixture lamps while using existing ballasts. Built with a 4-pin G24q base, this model delivers about 1,050 lumens of neutral white light at 4000K with a color rendering index (CRI) of 80 or higher, suitable for common indoor applications that call for bright, steady illumination. It is intended for vertical installations and is not dimmable or suitable for fully enclosed fixtures. The design supports plug-and-play installation by being ballast-compatible, reducing the need for wiring changes and enabling a straightforward retrofit in compatible CFL-equipped fixtures.
Key construction and features include a ballast-compatible design that allows direct replacement of conventional 13W–42W G24q CFL lamps, with an operating temperature range from -20°C to 45°C (-4°F to 113°F). The lamp is UL Classified and UL Recognized, and it is listed on the DLC QPL, which can be relevant for project qualification and energy-efficiency incentives. While the unit provides energy savings and longer life relative to traditional CFLs, it is specified as non-dimmable and should not be used in fully enclosed fixtures. Each package contains one lamp, and Keystone offers a five-year warranty against defects under typical use.
When considering a retrofit, verify ballast compatibility using Keystone’s guidance to ensure a seamless cross-reference with your existing CFL ballast lineup. This product is suitable for recessed downlights, wall sconces, and surface-mount fixtures that accommodate a 4-pin G24q base, with the understanding that ballast compatibility and fixture ventilation can influence performance and longevity. Always confirm manufacturer compatibility lists and installation requirements before replacing CFLs in commercial or residential lighting fixtures.
