SATCO Lighting S9640 16.5W, LED BR40, 4000K, 103 degree Beam Angle, Medium Base, 120V, Dimmable

No. The S9640 is an open rated lamp, so it should only go in open or ventilated fixtures and recessed cans that are not sealed. Enclosed fixtures trap heat around the driver and shorten lamp life. If the can has a sealed trim or glass cover, pick a lamp specifically rated for enclosed use instead.

Yes, close to it. The S9640 draws 16.5 watts and puts out 1200 lumens, rated as an 85W incandescent equivalent. In a corridor or lobby with a row of BR40 cans you get the same apparent brightness at roughly a fifth of the load, drawing 0.138 amps per lamp on a 120V 60Hz circuit.

The S9640 is dimmable on 120V line voltage. It is an LED lamp, not an incandescent, so it performs best on a dimmer rated for LED loads; older incandescent-only dimmers can flicker or drop out at the low end. It is not a three-way lamp, so do not use it in a three-way socket expecting stepped output.

4000K is neutral white, cleaner and less yellow than the 2700K to 3000K most apartments and hotel rooms use. It suits corridors, laundry rooms, parking garages, back-of-house and retail where you want a crisp look. If you are relamping a unit interior that currently reads warm, this will look visibly cooler beside them. Color rendering is 80 CRI, and the lamp is not color-selectable, so what you order is what you get.

It carries a damp location rating and is listed for indoor use, so a covered soffit, bathroom or shower can with no direct water contact is acceptable provided the fixture is not sealed. Do not use it anywhere exposed to rain or direct spray; that needs a wet location lamp.

The beam spread is 103 degrees, a wide flood. That is broad enough for general ambient washing in corridors and lobbies rather than accenting artwork. The lens is frosted, which softens the edge of the beam and reduces hot spots on the ceiling plane, so overlapping pools blend rather than scallop.

No. The S9640 is not DLC approved, so it will not qualify under programs that require a DesignLights Consortium listing. It is FCC compliant for electromagnetic interference.

Average rated life is 25,000 hours. Run continuously that works out to just under three years; on a 12 hour per day schedule it is closer to five and a half years. That is the number to plan a group relamp cycle around in stairwells and corridors where lift access is the real cost.

Burning position is universal, so the lamp can run base up in a recessed can, base down in a pendant, or horizontally in a wall wash or track head without affecting rated life.
