Lighting is always an issue during crawlspace work. This 50-ft. string of virtually indestructible LED lights for indoor or outdoor use saves time during installation, with no need to drag lights and drop cables all over the crawlspace. Each of the five lights includes a carabiner to make installation simple. The five lights together use just 55 watts and produce 5,000 lumens with an LED life of 40,000 hours. You can leave it as a permanent installation to light the way for others, or use it to brighten other areas such as attics, patios, camping, construction sites, etc. You can connect up to 10 sets of lights, giving you a maximum 500-ft.-long light chain. The lights are cool to the touch and include a three-year limited warranty.
