SATCO Lighting S39715 7W LED Downlight Retrofit, 4in, 4000K, 120V, Dimmable

Yes, the S39715 is a 4 inch downlight retrofit. The trim measures 5.31 inches in diameter, so it overlaps the ceiling opening, and the body is 2.88 inches high, which is the depth you need clear inside the housing above the ceiling line. Shallow remodel cans with wiring stuffed in the top are where depth gets tight, so check that 2.88 inches before you order a pallet of them.

It carries a wet location rating, so a shower trim or a covered porch can is fine electrically. Satco classifies it as an indoor product, so keep it under cover rather than fully exposed. It is cULus certified and classified.

The S39715 is fixed at 4000K neutral white and is not field selectable, so it will not blend into a run of 2700K or 3000K warm cans. If you are patching into an existing building, match the color temperature of what is already installed or relamp the whole room. Wattage is fixed at 7W as well, so there is no switch to set on the back.

Yes, it is dimmable on 120V line voltage. As with any low-wattage LED retrofit, a legacy incandescent dimmer sized for several hundred watts may not hold a stable low end on a single 7W load, so pair it with an LED-rated dimmer and group enough fixtures per circuit.

Yes, the S39715 is listed as Title 24 compliant, which matters if you are permitting residential or commercial work in California. It is also RoHS compliant and FCC compliant.

The LED is rated for 50,000 average hours. On a 12 hour a day corridor schedule that is over 11 years of service. The LED is integrated, not a replaceable lamp, so at end of life the whole retrofit module comes out and a new one screws in.

Body and base are thermoplastic (PBT), finished in white, in a round utility trim. Each unit weighs 0.33 lb, which is light enough that the existing lampholder and torsion clips carry it without any added support.
