A Micro USB charging port offers a backup option, topping up the battery in around 4 hours when sunlight alone isn't enough. An automatic light sensor switches the lights on at dusk and off again at dawn, so there's nothing to remember to do manually.4 Lighting ModesSteady lightSlow flashQuick flashPulsating lightBuilt to LastWith an IP65 waterproof rating, the string lights and solar panel are safe to use and touch even in wet conditions. The LED bulbs are rated for a 30,000 hour lifespan — roughly 10 times longer than an equivalent tungsten bulb — so they're built for years of seasonal use rather than a single summer.Where It Works BestGarden parties and outdoor entertainingWeddings and celebrationsPatios, decking, and pergolasBalconies and terracesCamping and off-grid outdoor spaces.
