SATCO Lighting S21806 9.8W, A19 LED, 4000K, Candelabra Base, 220 degree Beam Angle, 120V

Yes. The S21806 is an A19-shape LED lamp on a candelabra base, so it threads into the smaller candelabra sockets used in chandeliers, sconces and some decorative fixtures rather than a standard medium socket. Note the shape: it carries full A19 bulb geometry on a small base, so check that the fixture shade or glass has room for an A19 envelope before committing to a fleet order.

Yes, it's a dimmable lamp. On 120V line voltage it will dim, but as with any LED, performance depends on the dimmer being LED-rated. If you're swapping out incandescents on an old magnetic or high-wattage rotary dimmer, expect to replace the dimmer with an LED-compatible one to avoid flicker or drop-out at the low end.

4000K is a neutral white, noticeably cleaner and less yellow than the 2700K soft white most residential tenants expect. It reads well in corridors, laundry rooms, stairwells, offices and back-of-house areas. If you're mixing it into a unit interior alongside existing 2700K lamps, the color difference will be obvious, so standardize a space at one temperature.

The 220 degree beam angle means light spreads out well past straight down, close to omnidirectional, so the lamp fills a space the way an incandescent A19 does. That makes it workable in open-bottom shades, exposed chandelier arms and bare-socket fixtures where a narrow-beam LED would leave the ceiling dark.

80+ CRI is the standard commercial color-rendering level and is accepted for corridors, offices, storage and general common-area lighting. Where color judgment actually matters, such as retail merchandise display, a salon, or healthcare exam rooms, specifiers typically call for 90+ CRI instead.

Frost is the only finish offered. The frosted plastic envelope diffuses the output so you don't see individual diode hot spots, which matters in open fixtures where the lamp is in direct view.

The envelope is plastic, not glass, and the lamp weighs 0.05 lb. For multi-family and student housing that's a practical advantage: it won't shatter if a tenant drops it during a swap, and the low weight is easy on candelabra sockets in older chandeliers and fan light kits.
