Sunco Dusk to Dawn LED Outdoor Bulbs ST64 Edison Style — 800 LM, 7W, 4000K Cool White, E26, 4 Pack

Meet the Sunco Dusk to Dawn LED outdoor bulbs, blending classic Edison-style filament aesthetics with modern efficiency. These ST64 (and ST19) bulbs fit standard E26 bases and provide an inviting, bright exterior ambiance. A built-in photocell automatically activates the bulbs after sunset and deactivates them at dawn, delivering a hands-off lighting solution that suits changing routines and seasons. The durable, weatherproof design stands up to rain, wind, and temperature shifts, making them a practical upgrade for porches, patios, driveways, and outdoor string lights. Note: this bulb is non-dimmable.

What makes these bulbs compelling is the combination of form and function. The 800 lumens produced at 7 watts offer a clear, even glow that reads as modern rather than harsh. The 4000K cool white color provides crisp visibility for outdoor paths and entryways while maintaining a welcoming atmosphere. The filament-style look adds a nostalgic touch without the heat or maintenance of traditional incandescent bulbs. The lamps are UL certified, free of mercury, and emit no UV or IR, supporting safer outdoor lighting across seasons.
