SATCO Lighting S12421 6W A19 LED, Silver Crown, Medium Base, 2700K, 90 CRI, 120V

Yes on both. The S12421 carries a wet location rating and is listed for indoor and outdoor use, so covered porches, exterior sconces, and bathrooms are all in scope. It is also cleared for both enclosed and open fixtures, which matters because many LED lamps are open-fixture only and fail early inside a sealed globe.

The bulb is dimmable and runs on standard 120V, 60Hz line power. One practical caution for property managers swapping a fleet of incandescents: at 6 watts and 0.050 amps, a single LED draws far less current than the old lamp, so an older dimmer with a high minimum load may flicker or buzz until enough lamps are on the circuit. LED-rated dimmers avoid that.

The silver crown is a reflective coating on the top of the glass bulb. It blocks direct downward glare from the tip and bounces light back up, so the light reads as indirect. That makes the S12421 a fit for exposed-bulb pendants, bare-socket fixtures, and open shades where someone sits under the lamp and would otherwise stare into the LED filaments.

It rates 90 CRI, which is well above the 80 CRI typical of commodity LED lamps and is the usual threshold for spaces where color accuracy matters: guest rooms, restaurants, showrooms, and merchandise display. Paired with 2700K it gives a warm, incandescent-looking light with accurate skin tones and fabric color.

No to both. The S12421 is a fixed 2700K lamp with no CCT selection switch, and it is not a 3-way bulb, so in a 3-way socket it will run at a single output level. If you need multiple light levels, use it on a dimmer instead.

Burning position is universal, so the S12421 can be mounted base-up, base-down, or horizontally without affecting performance or life. It is rated 15,000 average hours.

Beam spread is 320 degrees, close to the omnidirectional output of a traditional incandescent. That comes from the LED filament construction rather than a flat chip-on-board, so it fills a shade or a globe evenly instead of throwing all the light in one direction. Standard plastic-domed LED A19s are usually much narrower.

Glass lens with an aluminum and glass base assembly. It is a true glass filament lamp, not a plastic-diffuser LED, which is why the silver crown coating and the exposed filament look work visually in open fixtures.

No. The bulb is not DLC approved, so it will not qualify under programs that require DesignLights Consortium listing. It is FCC compliant and cleared for sale in California.
