Bsc Preferred 573428 A19 40W Dimmable Led Bulb 2-pack

Product Description

The BSC PREFERRED 573428 is a two-pack of 40-watt equivalent A19 dimmable LED light bulbs designed for residential lighting applications. These bulbs use light-emitting diode (LED) technology to deliver full-spectrum, high-quality natural light at a fraction of the energy draw of traditional incandescent bulbs. Rated for up to 15,000 hours of service life, they are built for long-term use in standard residential fixtures. The bulbs dim smoothly down to 10% of full light output and are compatible with most standard dimmer switches. Each bulb ships in plastic-free packaging.

These A19 bulbs are suited for standard residential light fixtures including table lamps, floor lamps, ceiling fixtures, and enclosed or open sconce-style housings. The classic A19 form factor makes them a direct physical replacement for traditional 40-watt incandescent bulbs. Electricians and facilities maintenance technicians commonly specify LED replacements of this type during retrofits and fixture upgrades in residential and light commercial environments.
