Extension cords running across your patio, lights that cut out when a cloud rolls in, and bulbs that shatter the moment something brushes against them — outdoor lighting has always come with trade-offs. These solar outdoor string lights charge all day and turn on automatically at dusk, with shatterproof ST38 Edison bulbs that glow warm and steady for 10+ hours on a full charge.

Why It Stands Out
✓ Solar + Type-C USB dual charging — charges via the monocrystalline solar panel during the day, with a Type-C USB backup for cloudy days so you're never without light.
✓ 10+ hour runtime — 1,800 mAh battery delivers 10+ hours of light on a full solar charge or 5 hours of USB charging.
✓ Auto dusk-to-dawn sensor — turns on automatically at dark and off at daylight with no manual switching required.
✓ 8 lighting modes via remote — automatic cycling, flash mob, breathe, candles flicker, slow flashing, flash, fireworks, and solid on. Plus timer options (4H / 6H / 8H) and dimming (25% / 50% / 75% / 100%).
✓ Shatterproof replaceable bulbs — ST38 Edison bulbs on an E12 base resist impact and are individually replaceable, so one broken bulb doesn't end the string.
✓ IP44 weatherproof — rated for rain, wind, snow, and sun exposure for reliable year-round outdoor use.

Where These String Lights Work Best
Hang them across a patio, pergola, gazebo, or backyard deck for bistro-style ambience. String them over a garden path, umbrella, or along a fence line. Use them for weddings, outdoor parties, Christmas gatherings, café terraces, or commercial spaces. The solar panel stakes into the ground or mounts on a wall, so placement is flexible wherever the sun reaches.

How the Solar Charging Works
The monocrystalline silicon solar panel absorbs sunlight during the day and stores energy in the 1,800 mAh battery. A full charge from direct sunlight takes approximately 10 hours and powers the lights for 10+ hours. On overcast days, connect the Type-C USB cable directly to the battery box for a 5-hour charge. The dusk-to-dawn sensor detects ambient light and switches the lights on and off automatically — no timer to set manually.

Setup and Placement
Remove the battery separator from the remote before first use. Stake the solar panel into the ground in a location that receives direct sunlight, or use the included wall bracket to mount it. The lead cable from the panel to the first socket is 200 cm, with 56 cm spacing between each of the 15 sockets and a 10 cm tail at the end. Screw each ST38 bulb into its E12 socket, hang the string using the built-in hooks on each socket, and the lights will turn on automatically at dusk.
Care and Storage
Wipe the solar panel surface with a clean, dry cloth periodically to maintain charging efficiency. The string and bulbs are IP44 rated for outdoor use but should not be submerged. If storing for the off-season, remove the string from outdoor exposure and store in a dry location. Replacement bulbs use an E12 base and are available separately if any bulb reaches end of life (rated at 25,000 hours).
