SATCO Lighting S28770 11.5W, A19 LED, 5000K, Medium Base, 220 degree Beam Angle, 120V, 4-Pack

No. The S28770 is a non-dimmable lamp, so it should only go on a standard on/off circuit. Put it on a dimmer and you risk flicker, buzz, or early failure. For tenant units or conference rooms where someone will eventually install a dimmer, spec a dimmable A19 instead. It is also not a three-way lamp, so it will not step through levels in a 3-way socket.

Yes, it is an enclosed rated lamp, so it can go in closed globes, jelly jars, drum fixtures, and flush mounts where heat builds up. That is the main reason property managers pick this one for hallway and stairwell fixtures. It also carries a damp location rating, which covers covered porches and bathrooms, but it is an indoor lamp and should not be used in wet or exposed outdoor locations.

It replaces a 75W incandescent A19 while drawing 11.5 watts at 120 volts, and it puts out 1100 lumens. Current draw is 0.096A, so a 15A lighting branch circuit handles a large number of them, which is what makes a full-building relamp practical without touching the panel.

No. At 5000K this is a daylight white lamp, noticeably bluer and cooler than the 2700K soft white most residential fixtures run. Mixing them in the same corridor or unit will look wrong. 5000K suits garages, laundry rooms, shops, storage, and parking-adjacent areas where you want crisp task light. The color rendering index is 80, which is normal for general-purpose commercial lamps. The lamp is a fixed color temperature, not CCT selectable, so you cannot dial it back to a warmer setting.

No. This lamp is listed as non-compliant with California's Title 20 appliance regulations. Satco lists S8565 as the California-compliant alternative for this lamp, so that is what to order for a job site in California.

Yes, burning position is universal, so base-up, base-down, or horizontal all work. That matters for enclosed ceiling fixtures and can lights where heat collects around the base, and it is why the same lamp can be used across mixed fixture types in one building.

Beam spread is 220 degrees, so light goes forward and well out to the sides, but it is not a full 360-degree omnidirectional lamp. In a bare open-bottom fixture or a shade that needs uplight, expect less light above the bulb than an incandescent gave you. In downlight applications, ceiling fixtures, and enclosed globes, the 220-degree spread is what you want.

No, it is not DLC approved, so it will not qualify under rebate programs that require a DesignLights Consortium listing. If the rebate paperwork on your retrofit depends on DLC, you need a different lamp. The bulb is FCC compliant and runs on 120V, 60Hz power.

The S28770 ships as a 4-pack, and each lamp is rated for 15,000 average hours. For a common-area fixture burning roughly 12 hours a day, that is a multi-year relamp cycle, which is the point for MRO buyers stocking a standard A19 across a portfolio.
