Keystone’s Performance Series LED A and PAR lamps are the ideal, energy-efficient solution for both commercial retrofit and new construction applications. Performance Series LED lamps provide high lumen outputs at a fraction of the power consumption of legacy equivalents. Common applications for commercial A-Shape and PAR lamps include storefronts, parks, schools, churches, corporate campuses, and wherever there are recessed and outdoor corridors.
This Keystone Technologies Performance Series Non-Dimmable commercial LED A21 Light Bulb produces a color temperature of 2700K, 3000K, 4000K, or 5000K, operates on your existing 120-277V circuit and consumes just 20 watts of energy. These LED A21 commercial A lamps 150 watt incandescent equivalent retrofit lights generate 2,500-2,760 lumens and have a Color Rendering Index (CRI) of 80. These 120-277 volt commercial LED light bulbs fit fixtures with an E26 medium base.
These LED A21 bulbs are NOT dimmable but are RoHS compliant, UL Listed, and can be used in base-up or base-down positions. The bulb's dimensions are 2.56 inches wide by 5.26 inches MOL. The LED bulbs have a large metal heatsink for optimal heat dissipation and can be used in enclosed fixtures. These bulbs are damp location rated, Energy Star qualified, and have a rated life of 25,000 hours or a 5 Year limited warranty.
