SATCO Lighting S11634 12W LED Direct Wire Downlight, 3.5in, 3000K, 120V, Dimmable, Square, Remote Driver, Black

The S11634 is a 3.5 inch square downlight, and its overall body measures 4.38 x 4.38 x 3.00 inches. Plan on a 3.5 inch nominal square opening, with the 4.38 inch square trim face covering the cut edge and 3 inches of depth needed above the ceiling plane for the housing itself. The driver is remote, so it sits outside that 3 inch envelope and needs its own space in the cavity.

It is a direct wire ceiling-mount recessed retrofit that installs with springs into the ceiling opening, no can required. That is what the included spring clips do: they grip the drywall from above once the fixture is pushed up into the 3.5 inch hole. Because there is no housing to buy, it works well in remodel and occupied-unit work where cutting in cans is not practical.

No. It is fixed at 3000K, and the wattage is fixed at 12W as well. There is no CCT or wattage switch on this one, so if you are standardizing a building on a single warm-white look, that is an advantage: every unit comes out of the box matching, with no chance of an installer leaving a switch in the wrong position. If you need to tune color per space, you want a selectable-CCT downlight instead.

It's a dimmable 120V, 60Hz fixture and it is listed as California T24 compliant, which matters if you are specifying for a residential or commercial job in California where dimming and listed-fixture requirements are enforced. Since the driver is remote, match your dimmer to the driver Satco supplies with the unit; the spec sheet at media.satco.com covers the electrical detail.

Black only, with an aluminum base construction. The aluminum body handles heat sinking for the LED, and the black trim is the single finish offered under part number S11634, so if you need white or brushed nickel on the same ceiling you'll be ordering a different Satco part number rather than a finish option on this one.
