SATCO Lighting S28557 5.5W, A19 LED, Frosted, 2700K, Medium Base, 120V, 4-Pack

2700K is warm white, the same yellow-toned color as a standard incandescent bulb. If the other fixtures in the unit or corridor are on incandescent or 2700K LED lamps, the S28557 will blend. If your existing lamps are 3000K or 4000K, you will see a visible color difference between fixtures, so standardize on one color temperature across an opening or room.

At 5.5 watts, the S28557 sits in the range that replaces a 40 watt incandescent A19 in general lighting use. It draws the same 120 volts off the same medium base socket, so it is a direct lamp-for-lamp swap in an existing fixture.

The S28557 ships as a 4-pack of 5.5 watt frosted A19 LED lamps, all 2700K medium base. For multi-family or MRO turn work, that means one order unit covers a four-fixture unit or a small corridor run without mixing color temperatures.

The frosted glass diffuses the LED output, so you don't see the individual emitters as bright points. That matters in open fixtures, bare-socket porcelain keyless sockets, and shaded table lamps where a clear bulb would show hot spots. For a fixture where the lamp is visible as a decorative element, a clear lamp is the usual choice instead.

Treat it as a general purpose 120V medium base A19 lamp. The published data for the S28557 covers wattage, shape, color temperature, finish, base and voltage only, so match it to open or standard lamp applications and specify a lamp rated for enclosed or damp locations where the fixture calls for that rating.
