SATCO Lighting S21268 4W B11 LED, Clear, Candelabra Base, 90 CRI, 5000K, 120V

Yes on both counts. The S21268 B11 filament lamp is an enclosed rated lamp, so it can go inside a sealed globe or lantern without the heat shortening its life, and it carries a Wet location rating for indoor or outdoor use. That covers porch lanterns, covered entries, and enclosed sconces on a building exterior.

No, and this is the most common ordering mistake on candelabra lamps. At 5000K the S21268 is daylight white, a crisp blue-white next to the 2700K warm bulbs typically found in residential chandeliers. Mixing the two in one fixture reads as a defect. If you are relamping a fixture or a floor of units, change every lamp in the fixture to the same color temperature. This lamp is not CCT selectable, so the 5000K is fixed.

Burning position is universal, so the S21268 can be mounted base-up, base-down, or horizontal with no effect on its rating. That matters on chandeliers and sconces where sockets point in different directions, and on the 300 degree beam spread it gives near-omnidirectional output rather than throwing light in one direction only.

Yes, the S21268 is Title 24 compliant, which is what a California spec job or a JA8 review is going to ask about on a screw-base lamp. It is also FCC compliant. It is not DLC listed, so it will not qualify under utility rebate programs that require a DesignLights Consortium listing.

It is where people and finishes are on display. The S21268 is a 90 CRI lamp, high enough for hospitality lobbies, restaurant dining rooms, and retail where skin tones and fabric colors need to read true. Paired with the clear glass envelope and the visible LED filament, you get the exposed-filament look in a chandelier or open sconce where the bulb itself is part of the design.

Rated life on the S21268 is 15,000 hours. For a lobby or corridor fixture running about 12 hours a day that is roughly 3.4 years between relamps; on a dusk-to-dawn exterior lantern at around 12 hours a night the math is the same. That is the number to plan a building-wide relamp cycle around rather than swapping bulbs one at a time.

No. The S21268 is a single-output lamp and will not step through levels in a three-way socket. If you need staged output, dim it instead, since the lamp is dimmable on a 120V dimming circuit.

Clear glass envelope with a nickel plated aluminum base. The nickel plating is the reason it holds up in the wet-rated outdoor applications the lamp is rated for, where a bare brass or steel base in a coastal or damp lantern tends to seize in the socket over time.
