Super-bright 2,500-lumen LED light string is perfect for lighting up larger areas like outdoor sales lots, construction sites or patios. In fact, at a 10' height, you'll get 70 linear feet of light coverage. Each AC cord is 50' long with five high-intensity LED light heads, each casting 500 lumens. The cord can easily be mounted with carabiners and the lights' low power consumption makes it perfect to use with a generator. You can also connect up to 20 sets together for 100-light brightness!
