Overview

Upgrade outdoor lighting with the Sunco Dusk to Dawn LED bulbs, designed in a vintage Edison style while delivering modern efficiency. These ST64 (ST19) bulbs fit standard E26 bases and emit a warm 2700K soft white glow. At 800 lumens, they provide bright, welcoming illumination without the energy draw of traditional bulbs, using only 7 watts to achieve a 60W-equivalent feel. The result is a nostalgic appearance that complements porches, patios, and entryways while optimizing long-term running costs.

Designed for exterior spaces, this 4-pack brings consistent lighting across multiple fixtures, from porch lanterns to string lights. The filament look adds character to your outdoor zones, helping you set a cozy mood after dusk while maintaining a practical brightness level for safety and ambiance.

Smart, automatic dusk-to-dawn operation

The bulb relies on a built-in photocell sensor to automatically switch on when ambient light drops and to turn off near sunrise. This hands-free functionality helps you enjoy outdoor lighting without manual setup. Important: the bulb is non-dimmable, so it provides a steady, uninterrupted glow rather than adjustable brightness.

Rugged, weatherproof design

With weatherproof, dust-tight construction, these bulbs are built to withstand outdoor conditions. They perform well across driveways, patios, porches, decks, and even as accents for string lights, offering reliable brightness in differing weather scenarios.

Safety, quality, and support you can rely on

UL-certified for safety, Sunco’s bulbs contain no mercury and do not emit UV or IR radiation. The brand backs each purchase with a 5-year protection plan and USA-based support, reflecting a commitment to quality and customer assistance.
