Satco Lighting S21271 – Frequently Asked Questions
1) Can the Satco S21271 B11 candelabra LED be used in an enclosed fixture?
Yes. The S21271 is an enclosed rated lamp, so it can go in a closed globe, lantern, or sealed sconce without voiding its rating. It also carries a Wet location rating and is listed for indoor or outdoor use, which covers covered porch lanterns and exterior sconces that see weather.
2) What does 4000K look like, and will it match the other bulbs in my lobby?
4000K is a neutral, slightly cool white - noticeably crisper than the warm yellow of a standard incandescent candle bulb. If the rest of your fixtures are running 2700K, this will read blue against them. Match the whole run or expect a visible difference. The light temperature is fixed; the S21271 is not a CCT-selectable lamp.
3) Does the Satco S21271 meet California Title 24?
Yes, it's Title 24 compliant, which matters if you're specifying lamps for residential or commercial work in California. It's also FCC compliant. It is not DLC listed, so it won't qualify for utility rebate programs that require DesignLights Consortium listing.
4) Is the Satco S21271 dimmable, and does it work on my existing wall dimmer?
The lamp is dimmable on 120V, 60Hz line voltage. Worth knowing before you order a whole building's worth: at 0.033 amps each, a large chandelier may not pull enough load for an older incandescent-style dimmer to run smoothly. A dimmer rated for LED loads is the safer pairing.
5) How bright is a 4 watt B11 LED candle bulb compared to what I'm replacing?
350 lumens out of 4 watts, rated against a 40W incandescent. Light spreads over a 300 degree beam angle, so it throws in nearly all directions rather than forward only - which is what you want in an open chandelier or an exposed candelabra fixture where the lamp is seen from every side.
6) Why pay for a 90 CRI candle bulb instead of a standard one?
90 CRI means colors render close to natural light - skin tones, wood finishes, artwork, and fabric all read true. That's the reason hospitality, retail, and healthcare specs call for it. In a back-of-house corridor or a utility closet, a lower CRI lamp does the same job for less.
7) Can I install this candelabra LED base-up in a chandelier?
Burning position is universal, so base-up, base-down, or horizontal all work. That covers upward-facing chandelier arms, downward pendant sockets, and horizontal wall sconce cups without any derating concern.
8) Is this a clear filament bulb or a frosted one?
Frost. It's an LED filament lamp behind a frosted B11 torpedo-shape envelope, so the diffusion softens the filament strands rather than showing them sharply the way a clear glass version does. Pick clear if you want the exposed-filament look in an open fixture; frost is the choice where glare off a bare lamp is a problem.
9) How long will these last before my maintenance crew has to relamp?
Rated at 15,000 average hours. On a lobby or corridor fixture burning roughly 12 hours a day that's several years between relamps, which is the argument for standardizing a property on one lamp rather than chasing incandescent candle bulbs. Glass envelope with a nickel plated aluminum base.
10) Will this work as a 3-way candelabra bulb?
No. The S21271 is a single-level lamp, not three-way. In a 3-way socket it will operate at one output only. It does dim on a compatible 120V dimmer if you need variable output.
