SATCO Lighting S28563 10W, A19 LED, Frosted, 5000K, Medium Base, 120V, 4-Pack

No. The S28563 is a non-dimmable lamp. Put it on a dimmer circuit and you can expect flicker, buzz, or early failure. For tenant units or conference rooms with wall dimmers, specify a dimmable A19 instead and save the S28563 for switched-only circuits like corridors, stairwells, closets, and utility spaces.

At 800 lumens it matches the light output of a standard 60 watt incandescent A19 while drawing 10 watts, so it's a direct one-for-one swap in fixtures previously lamped at 60W.

5000K is daylight white, a crisp blue-white rather than the yellow of a 2700K incandescent. It reads well in garages, laundry rooms, basements, mechanical rooms, work areas, and exterior-protected fixtures. Most residential living spaces are lamped warmer, so if you're standardizing a building, don't mix 5000K and 2700K on the same floor or the difference is obvious from the hallway.

CRI is 90 or better, which is above the 80 CRI typical of commodity LED A-lamps. Colors, paint, wiring insulation, and finishes read accurately, so it's usable in maintenance shops, retail back-of-house, and any space where color judgement matters.

S28563 is sold as a 4-pack of 10W frosted A19 lamps. For a property manager relamping a fleet of units, count your sockets and order in multiples of four rather than per bulb.

The frost coating diffuses the output so you don't see individual LED points through the envelope, which matters in open shades, bare keyless sockets, and glass fixtures where the lamp is in view. If you want a visible filament look, a frosted A19 is the wrong choice.

The lamp body is plastic, not glass. That's an advantage in rental turnovers, stairwells, and maintenance closets where a dropped bulb would otherwise shatter. Each lamp weighs about 0.06 lb, so a 4-pack adds almost nothing to a service cart.

Treat enclosed-fixture use as a separate check. What the S28563 is confirmed for is 120V medium base A19 service, 10 watts, 800 lumens, non-dimmable. For an enclosed jelly jar, drum, or sealed outdoor fixture, specify a lamp that explicitly carries an enclosed-rating, since heat buildup is the main cause of early LED failure in those housings.
