The S4160 from Satco is a 40-watt A15 incandescent bulb designed for general household lighting with an E12 candelabra base. It is suitable for fixtures that accept small A15 bulbs. Key features include 420 lumens, dimmable operation, and a 1,000-hour average rated life.

Key Features and Benefits of This Incandescent Bulb

At 420 lumens, it provides soft general light for small fixtures. Dimmable operation lets you adjust brightness for comfort. The compact A15 shape, 3.36 inches long and 1.88 inches wide, fits narrow shades and fan fixtures. A 1,000-hour rated life means more frequent replacement than LED.

Where to Use the S4160 Incandescent Bulb

This bulb is well suited for fixtures such as ceiling fans and small lamps that take a candelabra E12 base, where a warm, familiar incandescent glow is wanted. The page does not list a location rating, so use it in dry indoor fixtures unless the fixture says otherwise.

Installation and Compatibility Checks

Check that your socket is an E12 candelabra base, that the fixture allows 40 watts, and that the bulb length of 3.36 inches fits under shades. It is rated 130 volts. Dimmable operation means you should still confirm your dimmer suits incandescent loads. Turn power off before replacing.

Additional Buying Context

This bulb is UL/CSA Listed, meaning it is listed for Canadian and U.S. safety standards. Warranty terms are not on the product page, so check Satco's manufacturer warranty page. If energy use matters, a dimmable LED candelabra bulb is a common alternative.
