SATCO Lighting S21833 3W B11 LED, Frosted, Medium Base, 2700K, 250 Lumens, 120V, 2-Pack

2700K is warm white, the same color point manufacturers use to match incandescent. In a building where some sconces still run incandescent or halogen candle lamps, a 2700K LED will read as the same warm tone rather than the bluish cast you get from 4000K or 5000K. Useful if you're changing out lamps a few at a time across a hallway or lobby instead of all at once.

Two. The S21833 ships as a 2-pack, so a four-light vanity or chandelier takes two packs to lamp completely. Worth counting sockets before ordering for a multi-unit turn.

Yes, it's a 120 volt line-voltage lamp, so it goes straight into standard North American residential and commercial circuits with no driver or transformer. Don't use it on a low-voltage 12V or 24V fixture.

The frost coating diffuses the output so you don't see individual emitters through the glass. That matters in open chandeliers and exposed sconces where the lamp is in the line of sight. If you want the visible filament look instead, you'd need a clear vintage-style B11, not this frosted version.
