SATCO Lighting S21213 5.5W G16.5 LED, White, Candelabra Base, 90 CRI, 3000K, 120V

Yes. The Satco S21213 is built on a candelabra base, so it threads into the small candelabra sockets used in chandeliers, wall sconces, and decorative fixtures. It runs on 120 volt line power, so no transformer or driver is needed. The G16.5 shape is the small globe bulb commonly used where the lamp is visible.

3000K, which reads as a soft warm white, slightly crisper than the yellow of an old incandescent. If the other lamps in the fixture are 2700K they will look noticeably warmer beside it, so for a chandelier where every socket is visible, lamp the whole fixture at 3000K rather than mixing.

That is the swap it is built for. It is a G16.5 globe on a candelabra base drawing 5.5 watts, so it drops into the same socket as a decorative globe lamp and pulls a fraction of the power. Check that your vanity fixture takes candelabra and not the larger medium base, since some bath bars use one and some the other.

The S21213 is a 90 CRI lamp, which puts it in the high color rendering range where skin tones, wood, and fabric hold their color instead of going flat. For hospitality lobbies, guest rooms, retail, and healthcare spaces where finishes are on display, that is the spec worth standardizing on. In a back of house corridor it buys you nothing.

No. It is a 120 volt lamp with the driver built into the bulb, so it wires up exactly like the incandescent it replaces, straight off standard line voltage. Nothing else to order to make it work.

Ask for Satco S21213. That single number covers the 5.5 watt G16.5 LED in white, candelabra base, 90 CRI, 3000K, 120 volt. There is only one configuration, so there are no suffixes or finish codes to specify. Satco builds the same G16.5 body in other color temperatures under separate part numbers, so if you want a warmer 2700K look, S21213 is not it.

White only, meaning a coated glass that diffuses the light instead of showing the LED filament or diodes. That is the one to use where the bulb is exposed at eye level and a clear lamp would be glary. There is no clear version of this particular lamp.
