SATCO Lighting S8791 20W LED A21, High lumen output, 2700K, Medium Base, 120V, 90 CRI, Dimmable

Yes. The S8791 is an enclosed rated lamp, so it can go in a closed globe, flush mount, or jelly jar style fixture without voiding its rating. It also carries a damp location rating, which covers covered porches and bathrooms, and it burns in any position (universal burning position). It is classed as an indoor lamp, so don't use it in a fixture exposed to direct weather.

The lamp is dimmable on 120V line-voltage dimming. It is not a three-way lamp, so it won't step through levels in a three-way socket. For smooth low-end performance, LED-rated (electronic low-voltage or LED/CFL compatible) dimmers are what to pair it with rather than older high-wattage incandescent rheostats.

Yes, that combination is what you want where color appearance matters. 2700K reads as warm white, close to the look of the incandescent lamps tenants are used to, and 90 CRI renders skin tones, wood, and fabric accurately. For back-of-house, garages, or parking areas, a cooler 4000K or 5000K lamp is the usual pick instead.

The beam spread is 280 degrees, so it throws light nearly all the way around the lamp rather than in a directional cone. That makes it a fit for table lamps, sconces, pendants, and open or enclosed ceiling fixtures where you want general room fill. If you need controlled downward throw into a recessed can, a BR or PAR reflector lamp is the better type.

Each lamp draws 0.167A at 120V and operates at 50/60Hz. Loading a 15A branch circuit to the usual 80 percent continuous limit (12A) gives roughly 71 lamps on the circuit from a lamp-load standpoint, before you account for anything else fed by that circuit.

Not on DLC-based programs. The S8791 is not DLC listed, and most commercial utility prescriptive rebates for general-purpose lamps run off the DLC qualified products list. It is FCC compliant, and it is marked lawful for sale in California, so there is no state sales restriction to work around.

No. The S8791 is a fixed 2700K lamp and is not CCT selectable, so there is no field switch or alternate color temperature on this part number. If a job spec calls for a different color temperature, you need a different Satco part number, not an option on this one.

It is rated 25,000 average hours. On a common-area fixture running roughly 12 hours a day that is about 5.7 years before rated life is reached, so it fits a standardize-once relamping program rather than annual bulb swaps.

Construction is die-cast aluminum with a PC (polycarbonate) lens, the aluminum serving as the heat sink that gets the lamp to its rated life. Both the housing and the lens are white, so it reads as a frosted white A-lamp in an open shade rather than a clear filament look. Lamp weight is 0.43 lb.
