S14 Incandescent Sign and Indicator Bulb by Satco
The S3965 from Satco is an 11-watt S14 incandescent bulb designed for indicator and sign lighting. It produces warm 2700K light at 80 lumens. Key features include an E26 medium base, a clear finish, a 360-degree beam, and dimmable operation.
Key Features and Benefits of This Incandescent Bulb
The low 80-lumen output suits signs and indicators where a soft glow is wanted rather than task lighting. The 100 CRI (Color Rendering Index) shows colors true, and the 360-degree beam spreads light evenly. It is dimmable, and the rated life is 2,500 hours.
Where to Use the S3965 Incandescent Bulb
This bulb is intended for sign and indicator fixtures that accept an S14 lamp with an E26 base. It is not a general room lamp, since 80 lumens is dim. The page does not list a location rating, so do not assume suitability for damp or wet areas.
Installation and Compatibility Checks
Check that your fixture takes an S14 lamp with an E26 base and has room for the 3.5-inch overall length and 1.75-inch maximum diameter. The bulb is listed at 130 volts, so confirm it suits your supply. If dimming, make sure your dimmer is compatible with incandescent loads.
Additional Buying Context
This is a traditional incandescent lamp, so expect more heat and a shorter life than an LED alternative. Quantity per package and warranty terms are not shown on the page, so confirm them before buying for a large sign or many fixtures.
