SATCO Lighting S12443 12.5W A19 LED, 100W Replacement, Clear, Medium Base, 3000K, 120V, 4-Pack

No. The S12443 is an open rated lamp, so it should not be installed in a fully enclosed fixture where trapped heat shortens LED life. For enclosed ceiling drums, flush mounts, or sealed jelly jars, specify a lamp rated for enclosed use instead. It is rated for wet locations, which covers exposed outdoor sockets and damp areas, but wet rated and enclosed rated are different things.

Only if those are also 3000K warm white. The S12443 is fixed at 3000K with no color-select switch, so it cannot be field-adjusted to 2700K or 4000K. If your existing lamps are 2700K soft white, you will see the S12443 read slightly cooler side by side. Its CRI is 90, which renders color better than a typical 80 CRI lamp, so mixing it with 80 CRI bulbs in the same room can also show a difference.

Yes. It is rated for both indoor and outdoor use and carries a wet location rating, so exposed exterior sockets are within spec. The one limit is the fixture itself: because it is an open rated lamp, a sealed outdoor fixture is not the right home for it.

Dimmable, yes, on a 120V 60Hz circuit. Three-way, no. The S12443 is a single-output lamp, so in a three-way lamp socket it will only light at one level rather than stepping through low, medium and high. Pair it with a standard LED-compatible dimmer, not a three-way switch socket.

The S12443 uses an LED filament behind a clear lens, so the light source is visible as a glowing filament rather than a diffuse white globe. That is the look you want in exposed fixtures, open-cage pendants, sconces, and hospitality fixtures where the bulb is part of the design. In a shade or a diffuser you would be paying for a look nobody sees, and a frosted lamp would be the better buy there.

Any orientation. Burning position on the S12443 is universal, so base-up cans, base-down pendants, and horizontal sconce sockets are all acceptable. The 320 degree beam spread means it throws light nearly all the way around the lamp rather than in one direction, so a sideways socket still fills the fixture.

Average rated life is 15,000 hours. It is not DLC listed, so it will not qualify under a utility program that requires a DesignLights Consortium listing. It is FCC compliant and marked lawful for sale in California.

S12443 ships as a 4-pack of the 12.5W clear A19 filament lamp. For a relamp spec, that is four medium base lamps per ordered unit.

Construction is aluminum and glass: a glass envelope over the LED filament with an aluminum medium screw base. It is a glass lamp, not a shatter-resistant plastic one, so for gym, kitchen, or food-service areas where a coated or poly-covered lamp is required by policy, this is not the one to spec.
