SATCO Lighting S11401 9W A19 LED, 5000K, Medium Base, 220 degree Beam Angle, 10-Pack

5000K is daylight white, a crisp bluish-white rather than the yellow of a 2700K incandescent. On a 9 watt A19 it suits garages, laundry rooms, basements, stairwells, storage areas, and back-of-house commercial spaces where you want task visibility. For apartment living rooms and bedrooms where tenants expect warm light, a 2700K or 3000K A19 is the closer match to what they are used to.

It ships as a 10-pack of the 9 watt A19 lamps, one carton of ten. That is the packaging property managers and MRO buyers usually want for re-lamping a floor or restocking a maintenance cart in one go.

Close to it. The S11401 puts out a 220 degree beam, so light throws down and well out to the sides rather than in a narrow cone. That matters in table lamps with shades, open ceiling fixtures, and bare-socket applications where an early-generation LED with a tight beam left dark spots on the ceiling. It is not a directional lamp, so don't specify it where you actually want a controlled beam, use a BR or PAR lamp there.

Only if the existing lamps are also 5000K. Mixing a 5000K daylight lamp beside a 2700K or 3500K lamp in the same room or corridor reads as an obvious color mismatch and generates tenant complaints. For standardizing a property, pick one color temperature across the openings and re-lamp a full run at a time, which is what the 10-pack carton is sized for.

A 9 watt A19 LED sits in the range normally sold as a 60 watt incandescent replacement, and it uses the same A19 shape and medium base, so it drops straight into the existing socket with no fixture change. Check the fixture's maximum wattage label is not an issue here, since 9 watts is far below any standard A19 fixture rating.

Frosted. The glass finish diffuses the source so you do not see hard diode images through the bulb, which is what you want in an open fixture or a shade where the lamp is visible. If a customer wants a visible filament look, this is not that lamp.

Order by Satco part number S11401. That designation covers the 9 watt A19, 5000K, medium base, frosted lamp in the 10-pack carton, so quoting it avoids ending up with a different color temperature or a single-bulb pack.
