SATCO Lighting S29877 4.5W B11 LED, Clear, Candelabra Base, 2700K, 350 Lumens, 120V

Yes. The S29877 is an enclosed rated lamp, so it can go in a closed globe, a lantern, or a sealed sconce without voiding the lamp's rating. It also carries a damp location rating, which covers covered porches, bathrooms, and canopies, but not direct wet exposure. Burning position is universal, so it can be installed base up, base down, or horizontal.

Dimmable, yes. At 4.5 watts it puts out 350 lumens and is the equivalent of a 40 watt incandescent candle lamp, so it drops into a dimmed chandelier or sconce circuit where 40W B11 candelabra lamps were used. Note that LED loads draw very little current (0.038A at 120 volts here), so an old incandescent dimmer with a high minimum load may not run well with only one or two of these on the circuit.

One for one. Each S29877 delivers 350 lumens against a 40 watt incandescent equivalent, so a six-arm chandelier that ran six 40W candles takes six of these and lands in the same brightness range while drawing 4.5 watts apiece.

That is the point of this build. The S29877 uses an LED filament behind a clear lens, so you see the filament strands rather than a frosted white dome, and the 2700K color is the warm tone incandescent lamps produced. Clear lamps show the filament and throw sparkle through cut glass or crystal, which is why they suit exposed-socket chandeliers and open lanterns. If your fixture has bare sockets at eye level and glare is a concern, a frosted or satin candle lamp is the better choice.

Yes, the S29877 is Title 24 compliant, which is what a California job needs for the high efficacy lamp requirement in residential permitted work. It is also FCC compliant. It is not DLC listed, so if a utility rebate on your project requires a DLC qualified product, this lamp will not carry it.

The S29877 is rated 15,000 average hours. On a lobby or corridor fixture burning roughly 12 hours a day that is about three and a half years between changes, and closer to a decade at four hours a day in a dining room. For a property manager with chandeliers on lifts or high ceilings, that rated life is the number that decides whether the labor of relamping is worth doing once or every season.

Beam spread is 360 degrees, so light comes off the whole lamp rather than being thrown forward like a reflector lamp. In an exposed-socket chandelier or a wall sconce that relies on the lamp itself for the glow, that omnidirectional output is what fills the room and lights the shade evenly. It is not the lamp for aiming light at a wall or an object.

S29877 is the Satco Lighting number, and it comes one way: clear finish, B11 candle shape, candelabra base, 2700K, 350 lumens on 120 volts. There is no frosted or alternate color temperature under that same number, so ordering by S29877 gets exactly this configuration every time, which matters when you are restocking a facility to keep the fixtures matched.
