SATCO Lighting S9319 3 Watt/9 Watt/12W, A19 LED, 3-way, Frosted, 5000K, Medium Base, 220 degree Beam Angle, 120V

It needs a true 3-way socket and switch to give all three levels. The S9319 is a genuine 3-way lamp (3W/9W/12W, 280/950/1200 lumens) with a medium screw base, so in a standard single-contact socket you will typically only get one output level rather than the full step sequence. Put it in a 3-way table or floor lamp socket to use it as intended.

No. The S9319 is not dimmable. Wired to a dimmer it can flicker, buzz, or fail early. Its three levels come from the 3-way socket contacts, not from a dimmer, so control it with the lamp's 3-way switch only.

Yes, most likely. At 5000K this lamp is a daylight white, a clearly cooler, bluer light than the 2700K soft white most residential fixtures use. It is not color-selectable, so the temperature is fixed. If you're standardizing a building on warm light, pick a 2700K or 3000K 3-way instead; use the 5000K where you want task brightness, like laundry rooms, shops, and work lamps.

Yes. The S9319 is an enclosed-rated lamp, so trapped heat inside a closed fixture or glass globe will not void its life the way it does with LEDs that are not enclosed rated. It also burns in any position, base up, base down, or horizontal.

No. This lamp is flagged non-compliant for California, meaning it does not meet that state's lamp efficiency and quality requirements. For California work you need a California-compliant 3-way LED A19.

It's rated for damp locations and listed for indoor use, so a bathroom or an enclosed, fully covered porch ceiling fixture is fine. Do not put it anywhere it will see direct rain or spray, that needs a wet-location rated lamp.

Rated life is 25,000 hours. At roughly three hours a day in a bedroom or living room lamp, that's a relamp cycle measured in years rather than months, which is the main reason property managers move 3-way sockets off incandescent. Actual hours depend on how much time the lamp spends on the 12W high step.

Not through DLC-based programs. This lamp is not DLC listed, and most commercial utility incentives for LED lamps require a DesignLights Consortium listing. If the rebate paperwork calls for a DLC qualified product ID, you'll need a different lamp.

The lamp uses a frosted lens over the LEDs, which diffuses the output and softens the hot spots you get from a clear bulb. With a 220 degree beam spread it throws light nearly all the way around the bulb, so it works in shaded table lamps and open fixtures where a directional LED would leave the shade dark.

CRI is 80, which is the standard general-purpose level for commercial and hospitality lamping, fine for corridors, offices, guest rooms, and back of house. For retail display or anywhere color matching matters, spec a 90+ CRI lamp instead.

It runs straight off 120 volt, 60 Hz line power with the LED driver built into the lamp. Screw it into a standard medium base socket, nothing else required.

The lamp is FCC compliant, so its driver electronics meet the federal limits on radio frequency emissions. That matters in hotel rooms and offices where a noisy LED driver can show up on nearby electronics.
