SATCO Lighting S21321 5.5W CA10 LED, Frost, Medium Base, 90 CRI, 4000K, 120V

Yes on both counts. The S21321 is an enclosed rated lamp, so sealed sconces, flush mounts and lanterns that trap heat are fine. It also carries a wet location rating and is listed for indoor or outdoor use, which covers exterior porch lanterns and post fixtures exposed to rain. Burning position is universal, so base up, base down or horizontal all work.

4000K is a neutral, slightly cool white, not the yellow-warm look of a 2700K incandescent candle. If the rest of your sconces are running warm white, this lamp will read noticeably cooler beside them, so standardize a whole run at once rather than mixing. The upside is 90 CRI color rendering, which keeps finishes, paint and skin tones looking true, useful in lobbies, corridors and hospitality spaces. Color temperature is fixed, not field selectable.

It's built as a 60W incandescent replacement and puts out 500 lumens at 5.5 watts. The 300 degree beam spread means light goes out in nearly every direction rather than in a cone, so it behaves like the incandescent candle it replaces in open sconces and chandeliers. At 0.046 amps on 120V, you can load a lot of them on one circuit compared with the incandescents coming out.

Dimmable, yes. The S21321 is a dimmable 120V, 60Hz lamp. Older magnetic-style dimmers originally sized for incandescent loads often need a minimum wattage to behave, and a few 5.5W lamps on one dimmer may flicker or drop out at the low end, so an LED-rated dimmer is the safer pairing on a retrofit.

No. The S21321 is not a three-way lamp, so in a three-way socket it will light at a single output level rather than stepping through low, medium and high. It is dimmable, so a dimmer gives you the range instead. For a three-way table lamp you need a lamp specifically listed as three-way.

Title 24 compliant, yes, and it is also FCC compliant. Worth noting for the spec file: it is not DLC listed, so if a utility rebate program requires a DLC qualified product, this lamp will not qualify for it.

Rated 15,000 average hours. On a corridor or exterior fixture running roughly 12 hours a day that is several years between ladder trips, which is the real argument for it over an incandescent candle in anything hard to reach. The lamp is a glass and nickel plated aluminum build with an LED filament, so visually it reads like a traditional filament candle behind the frost glass.

The frost glass diffuses the LED filament rather than leaving it bare, so you get a softer glow instead of visible hot spots in exposed shadeless sconces and chandeliers. It is the only finish this lamp comes in. If you want the filament clearly visible as a decorative element, a clear CA10 is the version to specify.

Order Satco Lighting S21321. That is the 5.5W CA10 frost LED, medium base, 90 CRI, 4000K, 120V. One configuration only, so there is no finish or color temperature suffix to add.
