SATCO Lighting S21272 4W B11 LED, Frost, Candelabra Base, 90 CRI, 5000K, 120V

Yes. The S21272 is an enclosed rated lamp, so it can go in a closed globe, lantern, or sealed sconce without the heat trapping shortening its life. It's also wet location rated and listed for indoor or outdoor use, which covers covered porch lanterns and exterior sconces.

No. The S21272 is 5000K, a daylight white, and it will read noticeably blue-white next to the 2700K or 3000K candle lamps most decorative fixtures are lamped with. Use it where you want a crisp daylight tone throughout the space, and lamp the whole fixture the same way rather than mixing colors in one chandelier. Color rendering is 90 CRI, so skin tones and finishes still read accurately.

Yes, the S21272 is Title 24 compliant, which is what matters for residential and multi-family work in California. It is also FCC compliant. It is not a DLC-listed lamp, so if your utility rebate program requires a DLC entry, this one will not qualify for it.

The lamp is dimmable. It draws 0.033A at 120V, 60Hz, so a handful of them on one circuit is a very small load, and that is the usual reason LED candles misbehave on older magnetic or high-minimum-load dimmers. If you're retrofitting a whole chandelier, plan on an LED-rated dimmer.

Burning position is universal, so base-up, base-down, or horizontal are all fine. That matters on chandelier arms that angle the sockets and on fan light kits that fire downward.

Beam spread is 300 degrees, so it throws light almost all the way around the lamp rather than forward only, which is what you want in an open chandelier or an exposed-socket sconce. The bulb uses LED filaments behind a frost glass envelope, so you get diffused light instead of visible filament lines and glare.

Average rated life is 15,000 hours. On a 4 hour per day lobby or corridor schedule that's roughly ten years between relamps, which is the argument for switching a large fixture count off 40W incandescent candles.

Neither. It is a fixed 5000K lamp with no CCT selection switch, and it is not three-way, so it will only operate at full output in a three-way socket. Dimming is handled by the dimmer, not the bulb.

Glass envelope with a nickel plated aluminum base, and it weighs 0.035 lb. Light enough that it is no concern on delicate chandelier arms or candelabra sockets on swing-arm fixtures.
