SATCO Lighting S9661 6W, A19 LED, Frosted, 3000K, European Medium base (E27), 220 degree Beam Angle, 230V, Non-Dimmable

No, it is non-dimmable. On a dimming circuit you should expect flicker, buzz, or no start at all, and the lamp life will suffer. Leave it on straight switched circuits. If the fixture is on a dimmer, either swap the control for a plain switch or specify a dimmable 230V E27 lamp.

It is a 40W incandescent equivalent, putting out 470 lumens on 6 watts. Same A19 shape, so it drops into the same shades and enclosures a standard 40W household bulb sat in, as long as the socket is E27 and the supply is 230V. Current draw is 0.026A, which is why a lot of these can share a circuit.

It carries a damp location rating, so a bathroom, a covered entry, or a soffit fixture that never sees direct water is fine. It is not wet rated, so keep it out of open weather, uncovered exterior fixtures, and anywhere it can be sprayed or rained on.

The S9661 is fixed at 3000K, a warm white, with a CRI of 80. It is not color selectable, so what you see is what every unit gives you, which is what you want when you are standardizing a property. If your existing lamps are 2700K they will read noticeably warmer side by side, and 4000K will read cooler and bluer. Mix them in the same room and the difference shows.

Yes, burning position is universal. Base up in a recessed or flush ceiling fixture, base down in a pendant, or horizontal in a wall sconce all work without affecting the rating.

Yes. At 220 degrees the light wraps nearly all the way around the lamp rather than throwing forward, and the frosted lens diffuses it, so it fills a room and open shades evenly instead of casting a hot spot. It is an ambient lamp, not a directional one, so do not specify it where you need a defined pool of light on a work surface or artwork.

No. It is not a three-way lamp, so in a three-way socket it will run at a single output level on whichever contacts energize it and will not step through the levels. Use a dedicated three-way LED if the fixture needs that function.

Rated 25,000 average hours. On a common-area fixture running roughly 12 hours a day that is in the range of five to six years between changes, which is the argument for putting it in high ceilings and stairwells where getting a ladder up is the real cost.

Plastic base, with a white housing and a frosted lens over the LED. Plastic keeps weight down in pendant and shade fixtures, and it will not corrode in a damp-rated location the way a metal shell can.

No, it is not DLC approved, so it will not qualify under DLC-based utility rebate programs. It is FCC compliant for electromagnetic interference, which matters if you are lighting near sensitive electronics.
