SATCO Lighting S9591 6W, A19 LED, Frosted, 3000K Medium Base, 220 degree Beam Angle, 120V, Non-Dimmable

No. The S9591 is a non-dimmable lamp. Put it on a dimmer and you'll get flicker, buzz, or no dimming range at all, and you risk shortening the lamp's life. Use it on standard on/off switched circuits only. It also isn't a three-way lamp, so it won't step through levels in a 3-way socket fixture.

Yes. The S9591 is an enclosed rated lamp, so it's approved for fully enclosed fixtures where heat builds up around the bulb. That covers glass drums, jelly jars, and closed-bottom flush mounts. Plenty of cheap A19 LEDs are not enclosed rated and fail early in those housings, so this is the spec to check when you're relamping corridor and stairwell fixtures.

Bathrooms and other damp interior spots are fine. The lamp carries a damp location rating, which covers humidity and condensation but not direct water contact. It is listed for indoor use, so don't put it in an open exterior fixture, a soffit exposed to blowing rain, or anywhere it can get wet. For that you want a wet location rated lamp.

No, not for sale into California. Satco flags this lamp as non-compliant with the California Title 20 appliance efficiency regulations, and lists S8558 as the Title 20 alternate substitute. If the property is in California, order the S8558 instead. Everywhere else the S9591 is the standard 6W 3000K A19.

A 220 degree spread throws light well past the horizontal, so it fills a shade and bounces off the ceiling instead of firing straight down like an early-generation LED with a flat top. The frosted lens diffuses the output so you don't see individual diodes through a clear shade. Practical effect: it behaves like the incandescent it replaces in table lamps, open pendants, and ceiling fixtures rather than leaving a dark ring near the socket.

Any orientation works. The burning position is universal, so base-up, base-down, and horizontal are all fine with no effect on rated life. That matters most in enclosed base-up cans, where heat collects at the driver end, and this lamp is also enclosed rated.

3000K is warm white, the usual choice for residential and hospitality interiors where 4000K reads too clinical. The 80 CRI rating is the standard general-purpose level for apartments, corridors, offices, and back-of-house. If you're lighting retail merchandise, artwork, or anywhere skin tone and fabric color are being judged, specify a 90+ CRI lamp instead. This lamp is also fixed color, not CCT selectable, so what you order is what you get on the wall.

No. This lamp is not DLC approved, so it won't qualify under rebate programs that require a DLC listing. It is FCC compliant for electromagnetic interference. If a rebate is driving the spec on a commercial retrofit, you'll need to pull a DLC-listed lamp instead.

The lamp has a white housing with a frosted lens, so it reads as a conventional soft white bulb rather than showing diodes or a clear glass filament look. In an open pendant or bare-socket fixture it hides the light source and cuts glare. If you're after the visible filament look for a cage or Edison-style fixture, a frosted A19 isn't the one.
