Satco-nuvo S21268 B11 Led Filament Bulb 4W 5000K Candelabra

Product Description

The SATCO-NUVO S21268 is a 4-watt B11 LED filament lamp designed for candelabra-base fixtures. It operates on 120 volts and produces approximately 350 lumens of natural white light at 5000K color temperature, making it suitable for applications where accurate color rendering is important. With a 90 CRI rating, it renders colors close to natural daylight. The clear glass envelope preserves the vintage filament aesthetic while delivering energy-efficient LED performance. Rated for 15,000 hours of service life, it replaces a standard 40-watt incandescent equivalent and is dimmable for flexible lighting control.

This lamp fits standard candelabra-base sockets and is appropriate for residential chandeliers, sconces, ceiling fans, and decorative fixtures where a visible filament look is desired. The 5000K daylight output suits task-oriented spaces such as kitchens, bathrooms, and workrooms, as well as retail or hospitality environments where accurate color representation matters. Electricians and lighting contractors specify this lamp as a direct retrofit for 40-watt incandescent candelabra bulbs.

Installation Notes

Installation is performed by a licensed electrician or qualified maintenance technician. Turn off power at the switch and allow the existing lamp to cool before removal. Verify the fixture and any connected dimmer are rated for LED loads before installing a dimmable LED lamp, as legacy incandescent dimmers may cause flicker or reduce lamp life. Confirm the fixture is rated for the operating wattage and base type before energizing.
