This pack of 2 LED solar fence post lights takes all the hassle out of installing lights on your fence or in your decking area. Each LED solar post light outputs 3 lumens of bright light, which is a significantly brighter light than regular solar powered lights.These post cap lights easily mount on top of standard 4" x 4" posts. You can install them on wooden piles or fences in the garden, decking, gate fence or any outdoor location you like.A robust and stylish stainless steel finish means this solar fence post light is designed to last against the elements while bringing a designer look to your surroundings, thus making them ideal for use in any outdoor space where no power supply is available.Solar garden lights are designed to charge a rechargeable battery during the day via the solar panel and automatically light up at night using the stored solar energy, making them environmentally friendly. The duration of the LED light output is determined by the amount of exposure the solar panel receives during the day and how bright a day it has been.The typical duration of light output times is Spring 2-5 hours, Summer Up to 6 hours, Autumn 2-5 hours, and Winter 0-2 hours.These high-quality solar lights come with batteries pre-installed and are ready to be used straight from the box. Replacement Smart Solar 1.2V AA Ni-Mh 300mAh batteries can be purchased separately (1 per post light).Solar LED lights are a cost-effective lighting solution but are also environmentally friendly, easy to install and require absolutely no wires or maintenance.To maintain the optimum performance we recommend regular cleaning of the solar panel on these outdoor lights.
