SATCO Lighting S11774 6W A19 LED, Medium Base, CCT Selectable, White Finish, 90 CRI, 120V, 4 Pack

No. The S11774 is a non-dimmable lamp. Put it on a dimmer circuit and you can expect flicker, buzz, or early failure. For a bedroom or dining space on a dimmer, specify a dimmable A19 LED instead and keep this one for closets, hallways, laundry rooms, and stairwells on plain toggle switches.

The S11774 is field-selectable between 3000K, 4000K, and 5000K, so one lamp covers warm white, neutral, and daylight. For a property manager that means one SKU on the shelf instead of three: set the warm 3000K in apartment living spaces and 5000K in back-of-house or garage fixtures, and you never have a mismatched bulb in a multi-lamp fixture again.

Yes. At 6 watts it puts out 470 lumens, which Satco rates as a 40W incandescent equivalent. Light spreads over a 220 degree beam angle through a frosted lens, so it throws much like the old bulb rather than beaming in one direction. If the fixture was running a 60W incandescent, this will read noticeably dimmer and you want a higher-lumen lamp.

Yes, it is an enclosed rated lamp, so a closed glass dome or jelly jar fixture is fine. Most LED A19 bulbs are not enclosed rated and cook their drivers in that kind of housing, which is why they fail early. It also mounts in any burning position, base up, base down, or horizontal.

Bathrooms and other damp interior spaces are fine, since the lamp carries a damp location rating. It is rated for indoor use only, so do not use it in an open exterior fixture exposed to rain or in a wet location. A covered, enclosed porch fixture that stays dry is the limit of where it belongs.

It will. 90 CRI renders paint colors, wood tone, and skin tone far closer to true than the 80 CRI lamps most budget LEDs ship with, which is what you want in a leasing office, a bathroom vanity, or any space a prospective tenant is walking through. Paired with the 3000K setting it reads close to the warm incandescent light people expect at home.

Not as a three-way. The lamp is single level, so in a three-way socket it will light at one brightness on whichever contact it makes and will not step through the levels. It is also non-dimmable, so there is no way to vary the output. For a three-way table lamp, order a dedicated three-way LED.

No, the S11774 is not DLC approved, so it will not qualify under programs that require DesignLights Consortium listing. If your rebate paperwork depends on DLC, you need a different lamp. The bulb is FCC compliant, so radio interference on the circuit is not a concern.

S11774 ships as a 4 pack, which suits stocking a maintenance cart or finishing a multi-lamp fixture in one order. Satco rates the lamp at 10,000 average hours. At roughly 4 hours a day in a residential fixture that is years of service before relamping.

Each lamp draws 0.05A at 120V. That is a very light load, so lamp count is rarely the limit on a lighting branch circuit, and a corridor or stairwell retrofit from 40W incandescent frees up substantial capacity. Size the circuit to your local code and the breaker rating as always.

It is a white-finish A19 with a frosted lens, so the diodes are diffused rather than visible as hot spots. In an open or clear-glass fixture it reads like a conventional frosted household bulb, not a filament-style decorative lamp. If you want visible filaments as a design element, this is the wrong lamp.
