SATCO Lighting S11772 12W A19 LED, Medium Base, CCT Selectable, White Finish, 90 CRI, 120V

No. The S11772 is a non-dimmable lamp, so it needs to run on a standard on/off switch. Putting it on a dimmer circuit can cause flicker, buzz, or early failure. It is also not a three-way bulb, so it won't step through levels in a 3-way socket. If the fixture is on a dimmer or a 3-way lamp, pick a dimmable or 3-way rated A19 instead.

The S11772 is field selectable between 3000K, 4000K, and 5000K, so one bulb covers warm white through daylight. That is the practical draw for a property manager stocking one SKU: set it to 3000K in apartments and lobbies, 4000K in corridors, 5000K in back-of-house, all from the same carton instead of three separate part numbers.

Yes, the S11772 is an enclosed rated lamp, so sealed flush-mount globes, jelly jars, and closed drum fixtures are fine. It is rated for damp locations and listed for indoor use, which covers bathrooms and covered breezeways but not open exposure to rain. Burning position is universal, so base up, base down, or horizontal all work.

The S11772 renders at 90 CRI, which is the threshold where skin tones, wood finishes, and merchandise colors stop looking washed out compared to typical 80 CRI lamps. For hospitality guest rooms, showrooms, salons, and unit turns where a leasing tour happens under the light, it is the spec worth paying attention to. A frosted lens spreads the output over a 220 degree beam, so there are no hot spots through a shade.

Each S11772 draws 0.100A at 120V, 60Hz. That is the number an electrician needs for load takeoff on a corridor or common-area circuit, and it lets you fill a branch circuit with a large lamp count where the old 75W incandescents would have maxed it out quickly. Size the actual circuit to your local code allowance for continuous lighting load.

No. The S11772 is not DLC approved, so it will not qualify on programs that require a DesignLights Consortium listing. If a rebate is driving the purchase, confirm which qualified products list your utility uses before committing to a quantity.

Rated at 10,000 average hours. For a common-area fixture running roughly 12 hours a day that is a relamping interval measured in years rather than months, which is usually the argument for switching a stairwell or corridor off incandescent in the first place.

The S11772 has a white finish housing with a frosted lens and a plastic base, so it reads as a conventional white A-lamp in an exposed socket or a clear glass shade. The frosted lens diffuses the source rather than showing individual diodes.
