Keystone’s Performance Series LED A Lamps are ideal for replacing high powered incandescent bulbs and lower wattage HID lamps, as well as in new construction applications. Our omnidirectional LED lamps produce a 330°/ 340° beam angle of uniform light.
Designed for use in commercial applications, the majority of these LED A Lamps operate off of universal input voltage (120-277V). Select A21 LED lamps use 120V input voltage, and feature phase dimming capability. Lumen output options range from 1,760 lm up to a powerful 4,850 lm.
Performance Series LED A-Lamps provide up to 140 lm/W for exceptional energy savings over incandescent or HID equivalents. For maintenance and replacement cost savings, A21 LED lamps have a 25,000 hour lifetime, and both A25 and A23 lamps have an impressive 50,000 hour lifetime. All Performance Series LED A Lamps are available in an E26 medium base and select models are also available in EX39 mogul base options.
Benefits of Performance Series LED A Lamps:
- Optimal energy savings up to 75% compared to legacy equivalent lamps
- Frosted lens and traditional shape for enhanced aesthetics
- Large metal heatsink for optimal heat dissipation
