SATCO Lighting S21840 4W CA10 LED, Clear, Candelabra Base, 2700K, 350 Lumens, 120V, 2-Pack

2700K is warm white, the same color temperature incandescent and halogen lamps produce, so the S21840 blends with existing incandescent candelabra lamps rather than looking blue or gray next to them. If the rest of the building is standardized on 3000K or 4000K, this bulb will read warmer than those.

Two. S21840 ships as a 2-pack, which is worth knowing when you're counting for a multi-arm chandelier. A six-light fixture needs three packs.

Standard 120 volt line voltage. The S21840 screws straight into a normal residential or commercial candelabra socket on a 120V circuit. It is not a 12V or 24V lamp, so don't put it on a low voltage transformer circuit.

Clear, like the S21840, shows the filament and throws sharper sparkle through glass or crystal, which is what you want in an exposed-bulb chandelier or a candle sconce with no shade. Frosted diffuses the source and cuts glare, so it's the better pick when the lamp sits at eye level or inside a clear glass shade where a bright point source would be uncomfortable.

Satco S21840 is the manufacturer part number, sold in a single clear finish version. It's the 4W CA10 clear, candelabra base, 2700K, 350 lumen, 120V lamp in a 2-pack.
