SATCO Lighting S9157 0.5W LED, C7, White, 2700K, Candelabra Base, 120V, Carded

Yes. The S9157 C7 LED carries a Wet location rating and is listed for indoor or outdoor use, so exterior sign bands, marquees, and covered walkway strings are fair game. It runs on standard 120V line voltage with a candelabra base, so it drops into existing C7 sockets on those runs. Burning position is universal, meaning you can install it base-up, base-down, or horizontal without affecting the lamp.

No. The S9157 is not dimmable. Put it on a dimmer circuit and you will get flicker, buzz, or no start at all, and you risk the driver. It is also not a three-way lamp. If the run is on a dimming control, either pull the dimmer and replace it with a standard switch or specify a dimmable C7 LED instead.

It is rated as a 7W incandescent equivalent, putting out 14 lumens at 0.5 watts. That is the same visual output you get from a standard C7 night light or sign lamp, at roughly a fourteenth of the draw. The 2700K color temperature matches the warm look of the incandescent it replaces, so a partial changeover across a fixture bank will not show a color mismatch.

Each S9157 draws 0.004 amps at 120V. On a 15 amp branch circuit loaded to the 12 amp continuous limit, that is a theoretical 3,000 lamps, so in practice the socket count on your string or sign, not the circuit, is the limiting factor. Swapping a run of 7W incandescent C7s for these cuts the connected load dramatically, which is the usual reason a property manager makes the change on a large sign or holiday installation.

Yes, the S9157 is Title 24 compliant, which is what a spec writer or institutional buyer needs for California work. It is also FCC compliant. It is not DLC listed, so if your utility rebate program requires a DLC qualified product, this lamp will not qualify for that incentive.

The S9157 has a coated white lens and a full 360 degree beam spread, so it lights evenly in every direction the way an incandescent C7 does. The white coating diffuses the LED so you do not see a bright point source through the glass. That matters in an exposed socket, a sign band, or a night light where the lamp itself is visible.

Average rated life on the S9157 is 25,000 hours. On a dusk-to-dawn sign running about 12 hours a day, that works out to roughly 5.7 years of service. For a facility relamping a large sign or a lobby display on a ladder or lift, that is the number that decides whether the changeover pays for itself in labor alone.

Color temperature is 2700K with a CRI of 80, the warm white that reads the same as the soft white incandescent and 2700K LED lamps already in most hospitality and multi-family common areas. Color is fixed, not selectable, so every lamp out of the box is the same 2700K, which is what you want when standardizing a fixture bank.

The S9157 ships carded, meaning each lamp is on its own retail blister card rather than loose in a sleeve or case pack. For an MRO storeroom that is useful, since each lamp stays protected and labeled on the shelf. There is a single version of the lamp, coated white at 2700K, so there is no finish or color option to specify when ordering.
