SATCO Lighting S11456 13W A19 LED, 4000K, Dimmable, Medium Base, 230 degree Beam Angle, 4-Pack

Yes. The S11456 is an enclosed rated lamp, so it can go in a closed glass globe, a flush mount dome, or a jelly jar without voiding its use. It is also damp location rated, which covers covered porches and bathrooms, but it is an indoor lamp, not a wet location lamp exposed to direct rain. Burning position is universal, so base up, base down, or horizontal all work.

The lamp is dimmable on 120V, 60Hz line voltage. Older incandescent-only dimmers were built for a resistive load of several hundred watts, and a single 13W LED, or even four of them, sits far below the minimum load those dimmers need, which is what causes flicker or drop-out at the low end. If the circuit is still on a legacy dimmer, use an LED-rated dimmer with a low minimum load for clean performance.

No. It is not a 3-way lamp. In a 3-way socket it will light at full output on the positions that energize the main contact and simply not step through the levels. For a 3-way fixture you need a bulb built with the second filament circuit. If the fixture has a separate wall dimmer instead of a 3-way socket, this lamp dims fine.

The S11456 is flagged non-compliant for California. California has its own state lamp efficacy and quality requirements for general service lamps, so for work in that state specify a lamp marked California compliant instead. Everywhere else, this is a standard 120V A19 replacement.

4000K is a neutral white, cleaner and less yellow than the 2700K warm white most residential tenants are used to. It reads well in kitchens, baths, laundry rooms, corridors, stairwells, and back-of-house areas. For living rooms and bedrooms where you want the look of the old incandescent, a 2700K or 3000K A19 is the closer match. The S11456 is a fixed 4000K lamp, not color selectable, so you cannot field-change the temperature.

230 degrees is a wide, near-omnidirectional spread, so light goes out sideways and well back past the base rather than throwing forward like a reflector lamp. That is what you want in open shades, bare sockets, sconces, and ceiling domes where the bulb has to fill the fixture. Paired with a frosted finish and 80 CRI, the output is diffuse rather than a hot spot.

Average rated life is 15,000 hours. On a fixture burning roughly 12 hours a night, that is in the neighborhood of three and a half years before rated end of life, so for continuous-burn common areas plan relamping on that cycle. The high heat conductive plastic housing with a polycarbonate base is also lighter and less breakage-prone than glass on a ladder change-out.

No. The S11456 is not DLC approved, so it will not be eligible under utility programs that require a DesignLights Consortium listing. It is FCC compliant for electromagnetic interference. If a rebate is driving the purchase, specify a lamp carrying the DLC listing the program requires.

Each lamp draws 0.108A at 120V, so the current per bulb is tiny. On a 15A branch circuit loaded to the usual 80 percent continuous figure, that is 12A of usable capacity, which is well over a hundred of these lamps before current is the limit. In practice the fixture count, wire runs, and dimmer load rating decide the layout long before amperage does.

80 CRI is the standard color rendering level for general lighting, and it is fine for corridors, offices, back-of-house, storage, and most multi-family interiors. Where color judgment matters, retail merchandise display, exam or treatment rooms, paint and finish work, specifications commonly call for 90 CRI or better, and this lamp will not meet that.

It is the frost finish, with a white housing. The frosted A19 envelope hides the LED emitters, so it is the right pick for open shades and bare-socket fixtures where a clear lamp would show individual diodes. If your spec calls for a visible filament look, this is not that lamp.
