The Norman Lamps LED-A15-3K-277V is a 5W LED A15 bulb engineered specifically for high-voltage 277V AC commercial and industrial electrical systems, while also supporting the full 120V to 277V range. Operating at 277V is the standard for large-scale facilities such as offices, warehouses, and retail spaces, where higher voltage circuits allow for reduced current draw and more efficient power distribution without step-down transformers.

This LED A15 bulb delivers more than 450 lumens of warm white light at 3000K, replacing 25W to 40W incandescent A15 bulbs at a fraction of the energy consumption. The frosted finish provides a smooth, diffused output across a wide 250-degree beam spread, making it well suited for open fixtures, wall sconces, hallway and stairway fixtures, commercial signage, display cases, and general ambient lighting wherever an E26 medium screw base socket is present. This LED A15 bulb also serves as a direct physical substitute for the G16.5 globe lamp shape in compatible sockets.

At just 2.80 inches in overall length and 1.80 inches in overall diameter, the compact A15 form factor fits in space-limited fixtures including ceiling fan light kits, small table lamps, and decorative pendant luminaires. The E26 medium screw base provides broad fixture compatibility across residential, commercial, and hospitality environments that are wired for 277V operation.

This LED A15 bulb is rated for 25,000 life hours, dramatically reducing replacement frequency and maintenance overhead compared to incandescent alternatives. The lamp is not dimmable and should be used on non-dimming circuits only. CE and RoHS certifications confirm compliance with applicable safety and environmental standards.
