Usually, when you have devices that run on electricity, the major problem is that they don't last all that long. This Is especially true for rechargeable LED lights. However, this particular LED firework garden light is different! Once fully charged during the day, the built-in 600mAh high-capacity battery is powerful enough to power the lights for over 10 hours! This ensures that your garden, patio, lawn, or even swimming pool will remain beautiful and colourful all through the night.
