SATCO Lighting S21874 5.5W A15 LED, Frosted, Medium Base, 2700K, 450 Lumens, 2-Pack

2700K is warm white, the same color tone as a standard incandescent, so it blends with existing incandescent or 2700K LED lamps in the same room. If your other fixtures are running 3000K or 4000K, this bulb will read noticeably yellower beside them. Mixing color temperatures in the same space is the most common complaint after a partial relamp, so standardize the room, not just the fixture.

At 450 lumens it covers the light output of a typical 40 watt incandescent A15, drawing 5.5 watts to do it. For a property manager relamping a building, that is the swap to plan on: pull the 40W candelabra-era A15s and drop these in, one for one, wherever the socket is medium base.

S21874 ships as a 2-pack. For MRO and multi-family buyers counting sockets, figure the order in pairs: a four-socket ceiling fan kit takes two packs.

The frosted glass diffuses the light so you do not see individual LED points through the envelope. That matters in open or exposed-socket fixtures, ceiling fan light kits, and clear-shade fixtures where a clear bulb would show hot spots. If you want a visible filament look instead, a frosted lamp is the wrong choice.
