SATCO Lighting S29558 9.5W, A19 LED, Frosted, 4000K, Medium Base, 220 degree Beam Angle, 120V, Non-Dimmable, 4-Pack

No. The S29558 is a non-dimmable lamp, so it should go on a standard on/off switch only. Putting it on a dimmer circuit can cause flicker, buzz, or early failure. If the fixture is on a dimmer, pick a dimmable A19 instead. It also won't work as a 3-way bulb.

Yes, it is an enclosed rated lamp, so closed globes, drum fixtures, and flush ceiling pans are fine. Burning position is universal, meaning base up, base down, or horizontal all work. That makes it usable in hallway cans, stairwell globes, and wall sconces without worrying about orientation.

4000K is a neutral, cool white, noticeably whiter than the 2700K soft white most apartments and homes use and warmer than a 5000K daylight lamp. If your corridors and common areas are already standardized on 4000K, these match. Mixing them beside 2700K lamps in the same room will read as a visible color difference. CRI is 80, which is typical for general-purpose commercial lamps.

No. Satco flags the S29558 as non-compliant for California, and lists S8562 as the Title 20 alternate substitute for that market. For jobs in CA, order the substitute rather than this lamp.

Bathrooms and other damp interior spots are fine; the lamp carries a damp location rating. It is classed for indoor use, so it is not the right choice for an open outdoor fixture exposed to rain or splash. For an unprotected exterior location, use a wet location rated lamp.

The lamp uses a frosted lens, which diffuses the output and softens the diode pattern instead of showing bare points of light. With a 220 degree beam spread it throws light down and well out to the sides, so it works in open shades, table lamps, and ceiling pans where you want broad room fill rather than a directional beam.

Each lamp draws 0.079A at 120V, 60Hz, and is rated for 15,000 average hours. At that draw you can put a large number of them on a standard 15A lighting branch circuit, which is what makes them practical for corridor and stairwell relamping across a whole building.

No. The S29558 is not DLC approved, so it will not qualify under rebate programs that require a DesignLights Consortium listing. It is FCC compliant for electromagnetic interference.

S29558 ships as a 4-pack of 9.5W frosted A19 lamps. Each lamp weighs 0.06 lb, so a case of these is light to handle for a tech working off a cart or ladder.

No. This is a fixed 4000K lamp with no CCT selectable switch. If you need one SKU that can be set to different color temperatures per location, choose a field-selectable lamp instead of this one.
