SATCO Lighting S9709 10W, LED A19, 3500K, Medium Base, 120V, 90 CRI

Yes. The S9709 is an enclosed rated lamp, so it can go in a closed globe, jelly jar, or a flush drum fixture where the heat has nowhere to go. It also burns in any position, base up, base down, or horizontal, so recessed cans and wall sconces are both fine. Location rating is damp and it is an indoor lamp, so a covered porch or bathroom is within its rating, but not a wet, exposed outdoor location.

3500K is a neutral white, cooler and less yellow than the 2700K soft white most residential tenants expect from an incandescent. For apartment living rooms and bedrooms it will read noticeably whiter than what was in there before. Where 3500K earns its place is corridors, lobbies, laundry rooms, offices, and back-of-house, where you want the space to look clean rather than warm. The S9709 is fixed at 3500K, not color selectable, so if you standardize a building on it, every socket you put it in will match.

Yes, the S9709 is California T24 listed, so it can be used where a job in California calls for a T24 compliant lamp. It is also FCC compliant. It is not DLC listed, so if a utility rebate program you are filing under requires a DLC listed product, this lamp will not qualify for that path.

The S9709 is a dimmable LED A19 running on 120V at 60Hz. Understand that a dimmer that was installed for incandescent lamps is switching a much larger load than a 10 watt LED, so a bank of these can land under the dimmer's minimum load and flicker or drop out at the low end. On retrofits where the old dimmer stays, put the full lamp count on the circuit before you judge the dimming performance.

It depends what the room does. The S9709 is 90+ CRI at 3500K, which renders skin tones, paint, fabric, and finishes far closer to how they look in daylight. That matters in retail display, healthcare exam and patient rooms, hospitality guest rooms, model units, and anywhere a color decision gets made under the light. For a stairwell, storage room, or mechanical space, the color rendering buys you nothing and a standard lamp does the same job.

It spreads 220 degrees, so light comes off the sides and back of the bulb, not just out the nose. That is what you want in a table lamp, a shaded floor lamp, a sconce, or an exposed socket where the shade needs to glow. The lens is frosted plastic, which diffuses the LED sources instead of showing them as bright points through a thin shade.

Rated at 25,000 average hours. On a corridor or exterior-covered fixture burning 12 hours a day that is roughly 5.7 years; on an office running 10 hours a day, five days a week, closer to 9.6 years. That is the number to run your relamp cycle and labor cost against, and it is why a 10 watt lamp replacing a 60 watt one pays back on ladder time as much as on the meter.

No. The S9709 is not a three-way lamp, so in a three-way socket it will run at a single output level and the low and medium positions of the switch will not step it. It is dimmable on a proper dimmer, but that is a different control method than a three-way socket. For a three-way fixture, order a lamp specified as three-way.

White housing with a frosted plastic lens, so it reads as a conventional white bulb sitting in an open socket rather than a bare filament or a yellow phosphor dome. Frost is the only finish it is built in. The base assembly is metal, plastic, and electronic components, which is standard for a driver-on-board LED lamp.

The part number to specify here is S9709, and that number is the 10W, 3500K, 90 CRI, medium base A19. Satco codes color temperature into the model number, so a warmer 2700K or 3000K version of the same 10W A19 is a different S-number, not an option on this one. When you order, give the wattage, the A19 shape, the medium base, and the exact Kelvin you want, and match against the Satco S-number that carries it.
