SATCO Lighting S28790 15.5W, A19 LED, 5000K, Medium Base, 220 degree Beam Angle, 120V, 4-Pack

No. The S28790 is non-dimmable. Put it on a dimmer circuit and you can expect flicker, buzz, or early failure. For dimmer-controlled fixtures in apartments or offices, specify a dimmable A19 LED instead and leave this one for switched-only circuits like stairwells, closets, corridors, and utility rooms.

No. The S28790 is a 120 volt lamp only. If your facility runs 277V branch circuits, which is common in commercial and industrial panels, this lamp will fail immediately. You need a lamp rated for that voltage or a fixture with a multi-volt driver.

5000K is daylight white, a crisp blue-white with no warmth to it. It reads well in garages, laundry rooms, basements, stairwells, back-of-house areas, and any space where you want things to look bright and clean. For unit interiors, lobbies, and guest rooms most property managers stay at 2700K or 3000K, so don't mix the S28790 into those fixtures or the difference will be obvious from the hallway.

The lamp uses a frost finish over the A19 envelope, which diffuses the light and softens the individual LED points, so it works in open-bottom fixtures, bare-socket porcelain keyless holders, and shade lamps where a clear bulb would show hot spots. The 220 degree beam angle spreads light nearly all the way around the lamp rather than throwing it forward, which is what you want in a table lamp or an open ceiling fixture, not in a recessed can where you need directional output.

The S28790 is rated 80+ CRI, which is the normal commercial benchmark and fine for corridors, stairs, storage, parking structures, and general office. Where color judgment matters, retail merchandise display, paint or fabric selection, salon or medical exam work, specify a 90+ CRI lamp instead.

S28790 ships as a 4-pack of frost-finish A19 lamps, all 15.5W/5000K. For MRO stocking, that means one order code gives you four sockets covered, which is a convenient unit for lamp changes across a floor or a stairwell run.

The A19 LED runs on 120V line voltage with a metal and plastic construction and a medium base. Enclosed-fixture and wet-location suitability is a per-lamp rating, so check the Satco spec sheet for S28790 before putting it in a sealed globe, a jelly jar, or an exterior fixture; heat build-up in an enclosure shortens LED life if the lamp isn't rated for it.
