SATCO Lighting S11330 20W, A21 LED, 3000K, Medium Base, 220 degree Beam Angle, 120-277V

No. The S11330 is a non-dimmable lamp, so putting it on a dimmer circuit can cause flicker, buzz, or premature failure. If the fixture is on a dimmer and you want dimming, you need a lamp specified as dimmable; otherwise the dimmer has to be replaced with a standard switch before you install these.

Yes. The S11330 is an enclosed rated lamp, so it can run inside a closed fixture or sealed glass globe where heat builds up. It also carries a damp location rating, which covers covered porches, bathrooms and similar spots, but not direct wet exposure.

It replaces a 125W incandescent. You get 2000 lumens out of 20 watts, so a fixture that previously drew 125W per socket now draws 20W for equivalent output. Across a large lamp count that is the number to use for load and energy calculations.

Yes. The S11330 accepts 120V through 277V at 60Hz, so the same lamp works on residential 120V branch circuits and on 277V commercial or industrial lighting circuits. Current draw runs 0.167A at the low end of the range down to 0.072A at the high end, which matters when you are counting lamps on a circuit.

The S11330 is fixed at 3000K, a warm white, and it is not CCT selectable, so there is no switch to change it in the field. If your other lamps are 2700K they will read noticeably warmer side by side, and 4000K lamps will read cooler. For a corridor or unit turnover, standardize the whole space on 3000K rather than mixing. Color rendering is 90+ CRI, which holds paint, wood tone and skin tone accurately in lobbies and hospitality spaces.

Any orientation is fine. Burning position is universal, so base-up in a recessed can, base-down in a pendant, or horizontal in a wall sconce all work without affecting the rating.

It is not a three-way lamp. Screwed into a three-way socket it will light at a single fixed output, and the switch positions will not step the brightness. For table and floor lamps where tenants expect three levels, you need a lamp specified as three-way.

Beam spread is 220 degrees, which is wider than a hemisphere, so light wraps back past the base rather than throwing straight down. That makes it a general ambient lamp for open fixtures, sconces and table lamps, not a directional lamp. If you need light aimed at a surface from a recessed can, a BR or PAR reflector lamp is the better choice.

No. This lamp is not DLC approved, so it will not satisfy a rebate or incentive program that requires a DesignLights Consortium listing. If your utility program is tied to the DLC Qualified Products List, you need a lamp carrying that listing. The S11330 is FCC compliant and is noted as lawful for sale in California.

Average rated life is 25,000 hours. On a 12 hour per day corridor or common-area schedule that is roughly 5.7 years of service, which is why these get spec'd for hard-to-reach fixtures where ladder time is the real cost.

The lens is white polystyrene plastic rather than glass, with a white housing, so the lamp reads as a plain white A-shape when off and diffuses the LED rather than showing hot spots when lit. The plastic lens is also less of a breakage risk than glass in tenant-occupied spaces.
