Philips 571497 150W A21 Warm Glow Dimmable Led Bulb

Product Description

The PHILIPS 571497 is a dimmable A21 LED bulb designed with a Warm Glow effect that shifts the color temperature as the light is dimmed, closely mimicking the behavior of incandescent bulbs. Rated as a 150-watt equivalent, it delivers high lumen output while consuming significantly less energy. The bulb is suitable for enclosed fixtures, making it a versatile choice for a wide range of residential and light commercial installations. Licensed electricians and lighting contractors install this type of fixture-grade lamp in standard medium-base sockets wherever directional or ambient warm-tone lighting is required.

This A21 LED bulb is intended for indoor applications including track fixtures, downlights, and high-hat (recessed can) luminaires. The Warm Glow dimming characteristic makes it well-suited for living spaces, dining areas, hospitality interiors, and similar environments where adjustable ambiance is a priority. Its enclosed-fixture rating expands placement options to globes, sconces, and covered ceiling mounts that would otherwise be incompatible with standard LED lamps.

Installation Notes

Installation of this lamp should be performed with the circuit de-energized at the breaker or switch before handling the socket. Verify that the dimmer switch is rated for LED loads, as legacy incandescent-only dimmers may cause flicker or reduce lamp lifespan. Confirm the fixture is rated for the wattage and form factor before installation. Work should comply with applicable NEC requirements for luminaire and lamp installations.
