SATCO Lighting S21288 4W B11 LED, Frost, Medium Base, 90 CRI, 3000K, 120V

Yes on both counts. The Satco S21288 is an enclosed rated lamp, so it can go in a sealed globe or lantern without voiding its rating, and it carries a wet location rating for indoor or outdoor use. That makes it usable in exterior post lanterns, covered entries, and porch fixtures exposed to rain.

It replaces a 40W incandescent candle lamp, drawing 4 watts and putting out 350 lumens at 120 volts. Current draw is 0.033A, so a circuit that once carried a few dozen 40W candles will carry far more of these - useful when you are relamping a large chandelier or a corridor of sconces on one branch circuit.

The lamp is dimmable on 120V, 60Hz line voltage. Dimming performance on any LED depends on the dimmer being LED-rated; legacy incandescent rotary dimmers are the usual cause of flicker or limited range at the bottom end. It is not a three-way lamp, so it will not step through levels in a 3-way socket.

At 3000K it sits in the warm white range, a little crisper than a 2700K incandescent candle but still warm rather than neutral. It is an LED filament lamp behind a frosted glass envelope, so the filament is diffused rather than exposed - good where the bulb is visible in a chandelier and you do not want glare. If your other fixtures are running 2700K clear candles, expect a visible difference in both color and sparkle.

Yes, the S21288 is listed as Title 24 compliant, which is what a California spec or inspector will ask about on a residential or hospitality relamp. It is also FCC compliant. It is not a DLC-listed product, so it will not qualify for rebate programs that require DLC listing.

Burning position is universal, so base-up, base-down, or horizontal are all fine. That matters on chandeliers and wall sconces where candle lamps point every direction, and it means one part number covers the whole fixture instead of sorting by orientation.

90 CRI is the spec to ask for where color appearance matters - guest rooms, lobbies, dining, and retail displays - because skin tones and finishes render closer to true than under a typical 80 CRI lamp. Paired with the frosted filament look, it is a reasonable standard-spec candle lamp for a hotel or restaurant relamp.

Average rated life is 15,000 hours. On a lobby or corridor fixture running roughly 12 hours a day that works out to several years between relamps, which is the main argument for swapping out 40W incandescent candles in high-fixture-count properties where labor, not the lamp, is the cost.

Beam spread is 300 degrees, so it is close to omnidirectional - light goes out the sides and up as well as forward. In an open chandelier or an upward-facing sconce that is what you want; a directional LED candle would leave the ceiling dark. The frosted glass spreads it evenly rather than showing filament hot spots.
