Lighting is always an issue during crawlspace work. This 50-foot 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 85 watts, and produce 7,500 lumens with an LED life of 50,000 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 400-foot-long light chain. The lights are cool to the touch and include a three-year limited warranty.
