SATCO Lighting S12442 12.5W A19 LED, 100W Replacement, Clear, Medium Base, 2700K, 120V, 4-Pack

No. The S12442 is an open rated lamp, so it should not go in a fully enclosed fixture. Heat trapped in an enclosure shortens LED life. It is wet location rated and approved for indoor or outdoor use, so open porch fixtures, post tops, and covered exterior sockets are fine as long as air can move around the lamp.

Yes. At 2700K this Satco A19 is the warm white that matches standard incandescent and halogen, so mixing it into a fixture or hallway alongside older lamps will not read cool or blue. It is a fixed color temperature, not a CCT-selectable lamp, so every bulb in the 4-pack burns the same warm tone with no switch to set. CRI is 90, which holds skin tones and finishes better than a typical builder-grade LED.

It is a dimmable lamp on 120V, 60Hz line voltage. Older incandescent dimmers will often work but can flicker or drop out at the low end with a load this small, so on a multi-fixture job it is worth wiring one circuit first before you buy for the whole building.

That is exactly what this one is built for. The S12442 uses LED filament construction behind a clear lens in an aluminum and glass body, so you see the filament strands rather than a frosted dome. In a chandelier, sconce, or open pendant where the bulb is visible it reads like a traditional clear incandescent. If the fixture leaves the bulb bare at eye level and you want less glare, choose a frosted lamp instead.

Any orientation. Burning position is universal, so base-up, base-down, or horizontal all work. Just remember it is open rated, which rules out a sealed recessed can with a lens cover.

320 degrees, which is close to the all-around throw of an incandescent A19 rather than the forward-throw pattern of a cheaper LED with a heat sink blocking the back. That matters in a table lamp, a shade, or an open ceiling fixture where light needs to go up as well as down.

No. The S12442 is a single-output lamp, so in a three-way socket it will light at one level only rather than stepping through settings. For a three-way table lamp you need a lamp specifically built for it.

The S12442 is rated 15,000 average hours. On a common-area fixture running roughly 12 hours a day that is around three and a half years of service. It ships four bulbs to a pack, which suits stocking a cart for multi-fixture relamping.

Yes, it is marked lawful for sale in California. It also carries FCC compliance, which is the relevant point if radio interference from LED drivers has been a problem in the building.
