SATCO Lighting S11486 15W PAR38 LED, 3000K, Medium Base, 120-277V, 90 CRI

No. The S11486 is a non-dimmable lamp. Wire it to a straight on/off switch. If it goes on an existing dimmer circuit you can expect flicker, buzz, or no start at all, so either swap the control to a standard switch or pick a lamp listed as dimmable.

Yes. The S11486 is a universal-voltage lamp rated 120V to 277V at 60Hz, so the same bulb works on standard 120V residential branch circuits and on 277V lighting circuits in commercial buildings. Current draw runs 0.125A at the low end of the range down to 0.054A at the high end. That means one part number can standardize a whole property instead of stocking separate 120V and 277V lamps.

Wet location rated, so it is approved for open outdoor fixtures, soffits, canopies, and enclosed shower or bath housings where water can reach the lamp. The lens is clear polycarbonate rather than glass, which holds up better to impact and to thermal shock from rain on a hot lamp.

The 40 degree beam on this PAR38 is a flood pattern. It covers merchandise displays, wall washes, lobby and corridor downlighting, and general accent work where you want an even pool of light rather than a tight punch on one object. For pinpointing a single piece of art or a jewelry case you want a narrower spot beam instead.

It does where color accuracy is part of the job. The S11486 is a 90 CRI lamp at 3000K, which renders skin tones, fabric, wood, and packaging close to how they look under halogen. That is the number specifiers call for in retail, hospitality, galleries, and healthcare exam areas. Standard 80 CRI lamps will look duller on reds by comparison, so do not mix the two in the same run of fixtures.

Yes, burning position is universal. Base up in a recessed can, base down in a pendant or gooseneck, or horizontal in a track head or wall-mounted flood, all are fine with no derating called out.

3000K fixed. This is not a CCT selectable lamp, so there is no switch on the body to move it to 2700K or 4000K. If you are matching existing warm white lamps across a building, order the 3000K part deliberately, and note it is a single-color-temperature SKU.

Not as a three-way. The S11486 is a single-level lamp, so in a three-way socket it will light at full output on the positions that energize its contact and stay off otherwise. For a three-position table lamp you need a lamp specifically built for three-way operation.

Yes, it is lawful for sale in California. That matters for distributors and property managers working under the state's lamp efficacy rules, where a number of older PAR38 halogen and lower-efficacy LED lamps can no longer be sold.
