These five long-life light-emitting diode (LED) lights produce 7,500 lumens and use just 70 watts. The lights are spaced 10 feet apart on a 50-foot cord. Each light has an extra-wide light spread with a super-bright beam. Connect up to eight sets for a maximum 400 feet. They are safe and cool to the touch, the company says, and come with a 3-year limited warranty. Each light includes a carabiner for simple installation. Leave it as a permanent installation, or use it to brighten other areas such as attics, patios, camping, construction sites, etc.
