SATCO Lighting S11428 6.5W, A19 LED, Dusk to Dawn With PhotoCell, 2700K, Medium Base, 320 degree Beam Angle, 120V

The photocell is built into the bulb. The S11428 senses ambient light and switches itself on at dusk and off at dawn, so you leave the fixture switch in the on position and nothing else is needed. That makes it a drop-in for porch lights, entry sconces, and stairwell fixtures where you would otherwise add an external photo control or a timer.

It is built for outdoor use and carries a damp location rating, so it works in a covered porch, soffit, carport, or enclosed entry fixture. Damp rated means it should not be in a spot where it takes direct rain or spray, so an open-bottom fixture in the weather is the wrong application. It is also enclosed rated, so a sealed jelly-jar or lantern with a closed globe is fine.

Yes. The S11428 puts out 800 lumens on 6.5 watts, which is the standard replacement level for a 60W incandescent A19. Colour is 2700K, the same warm white as the incandescent it replaces, with 80 CRI. Beam spread is 320 degrees, so it throws light nearly all the way around the bulb rather than in one direction.

No on both counts. This lamp is non-dimmable and is not a three-way bulb, so a dimmer circuit or a three-way socket will cause flicker, buzz, or no control at all. It also fights the photocell: the bulb wants constant power at the socket to decide when to switch itself on. Put it on a plain switched circuit that stays energized.

No. The S11428 is flagged non-compliant for California, so it should not be specified for jobs in that state. Property managers and distributors working CA projects need a Title 20 compliant lamp instead.

It uses a medium base in a standard A19 shape, so it screws into the same socket as an ordinary household bulb. Burning position is universal, meaning you can mount it base up, base down, or horizontal without affecting life or output.

Clear. The S11428 is an LED filament lamp with a clear polycarbonate lens, so the filament strips are visible through the envelope, the look people want in exposed lantern and carriage-light fixtures. If you need a diffused, frosted appearance to hide the source, this is not the lamp. The housing is polycarbonate and high heat conductive plastic rather than glass, which holds up better in exterior fixtures that get handled or hit.

No. The S11428 is not DLC approved, so it will not qualify for utility rebate programs or specifications that call for a DLC listed product. It is FCC compliant, which covers the electronic emissions side for residential and commercial installs.

It can be. The sensor reads ambient light at the bulb, so mounting it where a streetlight, a neighbouring wall pack, or an interior light spills onto the lamp can hold it off at night or cycle it. For dusk to dawn service, place the fixture where the bulb sees genuine darkness. Aiming the clear lens away from the competing source usually settles it.

No. This is a fixed 2700K warm white lamp with no CCT selection switch, so every unit puts out the same colour. For a property manager relamping a row of exterior fixtures that is an advantage, since there is no switch position to get set wrong in the field and no mismatched openings. If you need 3000K or 4000K somewhere in the building, that has to be a different lamp.
