SATCO Lighting S21266 4W B11 LED, Clear, Candelabra Base, 90 CRI, 3500K, 120V

Yes on both counts. The S21266 B11 filament lamp 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 covers covered entries, sconces under a soffit, and post lanterns where a standard candelabra LED would cook itself.

The S21266 is a dimmable lamp on a 120V, 60Hz circuit. It is not a three-way lamp, so it will not step through levels in a three-way socket. As with any LED retrofit on a dimmer originally sized for incandescent load, a whole chandelier of these draws very little current (0.033A each), which is where older dimmers can drop below their minimum load and flicker. An LED-rated dimmer is the reliable pairing.

The S21266 is listed as Title 24 compliant, which is the box a spec has to tick for lighting in California residential and multifamily work. It is also FCC compliant. Note it is not DLC listed, so it will not qualify for utility rebate programs that require DLC.

3500K is a neutral white, noticeably crisper than the 2700K warm glow most people associate with a decorative candelabra lamp. Pick the S21266 when you want the space to read clean and current, or when it has to match 3500K downlights elsewhere in the room. If you are matching existing incandescent chandeliers in a traditional lobby, a 2700K version will blend better. The 90 CRI on this one keeps skin tones and fabric colors accurate, which matters in hospitality and retail.

Burning position is universal, so base-up, base-down, or horizontal all work. That matters on candelabra fixtures, where the sockets in one chandelier often point in several directions and a position-restricted lamp would shorten life on half of them.

The S21266 uses LED filament construction in a clear glass envelope, with a 300 degree beam spread. That is near-omnidirectional, so it throws light up into the ceiling and out to the sides rather than down in a cone, which is what you want in a chandelier or sconce. The tradeoff with clear glass is a visible filament and some glare, so use it where the bulb is meant to be seen. Choose frosted if it sits at eye level with no shade.

No. It is fixed at 3500K with no CCT selection switch, so every lamp out of the carton matches the next one. If you are standardizing color across a building, that is the point in its favor; if you need field-adjustable color, this is not that lamp.

Satco S21266. It is the 4W B11 LED filament lamp, clear, candelabra base, 90 CRI, 3500K, 120V. Only one version is offered, the clear finish, so the part number alone pins the order.
