SATCO Lighting S21812 4.5W G16.5 LED, White, Candelabra Base, 2700K, 350 Lumens, 120V, 2-Pack

Yes on both counts. The S21812 G16.5 filament lamp is an enclosed rated lamp and carries a Wet location rating, so it can go in a sealed porch lantern, a post top, or a covered sconce exposed to weather. It is listed for indoor or outdoor use, and burning position is universal, so base up, base down, or horizontal all work.

Yes. At 4.5 watts the S21812 puts out 350 lumens and is rated as a 40W incandescent equivalent, so the light level in a chandelier or bath bar stays where it was while the draw per lamp falls to 0.038 amps on a 120V, 60Hz circuit. Useful if you're pushing a multi-socket fixture that was near its wattage limit.

Yes, it is Title 24 compliant, which is the box to tick on California residential and multi-family lighting work. It is also FCC compliant. It is not DLC approved, so if a commercial utility rebate program requires a DLC listing, this lamp will not qualify for it.

The lamp is dimmable. One thing to watch: it is not a three-way lamp, so it will not step through levels in a three-way socket the way a 40/60/100 incandescent does. For a chandelier on a dimmer, run it on a dimmer rated for LED loads and size the load to the 4.5 watts per lamp it actually pulls.

2700K is the warm color point that reads closest to a standard soft white incandescent, so mixing these into a building where some sockets still hold incandescent lamps looks consistent. Color is fixed, not selectable, so every bulb in a case is the same 2700K, which is what you want when you're standardizing lamps across a lobby or a corridor of units. CRI is 90, so wood tones and skin tones render well.

Close to it. The beam spread is 320 degrees, so it lights nearly the full sphere rather than firing in one direction. That matters in an open chandelier or an exposed globe fixture where the bulb is visible from every side and a directional LED would leave dark spots. It is an LED filament lamp inside a white finish glass globe, with glass and copper construction.

Rated at 15,000 average hours. On a common area fixture burning roughly 12 hours a day that's several years between ladder trips, which is the usual reason a property manager moves a chandelier or exterior sconce off incandescent candelabra lamps in the first place.

S21812 ships as a 2-pack of the 4.5W G16.5 white candelabra lamp. For a five or six light chandelier, count sockets and order packs accordingly so the whole fixture gets relamped at once and the color stays uniform.
