SATCO Lighting S11618R1 12W LED Direct Wire Downlight, Gimbaled, 4in, CCT Selectable, Round, Remote Driver, 850 Lumens, 120V

The S11618R1 has a 5.04 inch trim diameter and a 2.00 inch height, so the trim covers a nominal 4 inch cut opening and the housing body needs 2 inches of plenum depth above the ceiling. Because it is a direct wire fixture, there is no can required, but you do need that 2 inch clearance plus room to route the whip to the remote driver.

The driver is a separate box rather than being built into the trim, so it mounts in the ceiling cavity and connects to the light module by a lead. That keeps the fixture body shallow at 2 inches, which helps in tight joist bays and in insulated ceilings where a driver hanging off the back of the trim will not fit. It does mean you need accessible space to place and secure the driver near each opening.

Yes. The S11618R1 carries a Wet location rating and is listed for both indoor and outdoor use, which covers soffits, porch ceilings, and shower or tub enclosures where the fixture can see direct water. It is cETLus Listed.

It is CCT selectable across 2700K, 3000K, 3500K, 4000K, and 5000K, chosen at the fixture before you close up the ceiling. For a property manager standardizing a building, that means one SKU covers warm residential corridors at 2700K or 3000K and cooler back-of-house or garage areas at 4000K or 5000K. Wattage is fixed at 12W, so output stays at 850 lumens regardless of which color you pick.

Yes, it is California T24 Listed, which matters for new construction and retrofit permits in California residential and commercial work. It is also FCC compliant and RoHS compliant.

The 4 inch round trim is gimbaled, so the light module tilts within the housing to aim at artwork, a feature wall, or a sloped ceiling. If you need straight downward wash only, a fixed baffle trim is the simpler choice; pick the gimbal where you want aiming control after the ceiling is closed.

It is dimmable and runs on 120V at 60Hz. It draws 12 watts, so on a 120V branch circuit you can load a large number of these before the circuit becomes the limit; the practical ceiling is usually the dimmer's minimum load and LED compatibility, not the breaker.

No bulbs. The LED is integrated into the fixture, so there is no socket and nothing to relamp. Rated life is 50,000 hours, which for a corridor running 12 hours a day is roughly 11 years of service before lumen depreciation becomes the reason to replace it.

One finish only, white, on an aluminum base. The aluminum body is what handles heat sinking on the LED module, and the white trim is the standard match for painted ceilings across multi-family and commercial corridors.
