Satco S12448 185W A21 LED Bulb

The Satco S12448 is an 185 watt A21 LED lamp with a medium base and frost finish. It produces cool white light at 4000K and operates on 120 volt circuits. The dimmable design suits residential rooms needing high output from a standard socket. Rated life reaches 15000 hours for long service intervals.

Socket and voltage check

Verify the fixture accepts a medium base bulb and is rated for at least 185 watts. Confirm the circuit supplies 120 volts and uses a dimmer compatible with LED loads if dimming is required. Ensure the enclosure provides adequate ventilation for the lamp's thermal management. Buyers needing a different base type or lower wattage should select another model.

Frost finish and dimming

The frost finish diffuses the 4000K output for reduced glare in living spaces. Dimmable operation allows adjustable brightness without replacing the fixture's control gear. The 15000 hour rating reduces replacement frequency compared to shorter-life alternatives. No additional accessories or software are included with this lamp.
