SATCO Lighting S21333 5W BT15 LED, White, Medium Base, 90 CRI, 4000K, 120V

Yes. The S21333 is an enclosed rated lamp, so sealed jelly jars, closed globes and lanterns are fair game. It also carries a wet location rating and is listed for indoor or outdoor use, which covers covered porches, exterior sconces and similar spots.

It uses a medium base, which is the standard screw socket on ordinary North American lamps and fixtures. Runs on 120V at 60Hz, drawing 0.042A, so it drops straight into normal line-voltage residential and light commercial circuits.

Yes, the S21333 is dimmable. It is a single fixed color temperature lamp at 4000K, not CCT selectable, and it is not a three-way bulb, so don't put it in a three-way socket expecting three levels.

4000K is a neutral white, cooler and crisper than the warm 2700K look most residential interiors use. For corridors, laundry rooms, lobbies, stairwells and back-of-house it reads clean and matches typical commercial lamping. If you're relamping units where tenants expect a warm glow, spec a warmer color temperature instead. The 90 CRI rating means colors and skin tones render accurately whichever way you go.

Close to omnidirectional. The S21333 has a 320 degree beam spread, which is what you want in a chandelier, open shade, or exposed fixture where the lamp is seen from the side and below. It can also be burned in any position, base up, base down or horizontal.

Yes, the S21333 is Title 24 compliant, which matters if you're specifying lamps into California residential or commercial projects. It is also FCC compliant. It is not DLC listed, so it won't qualify for utility rebate programs that require DLC.

It's an LED filament lamp in a BT15 shape with a white finish, so the filaments are diffused rather than exposed clear glass. Construction is glass with a nickel plated aluminum base. Good where the bulb is visible but you don't want glare off bare filaments.
