Stretch 100 feet of bright, even work light across a job site with this string set of 10 bulbs spaced 10 feet apart, delivering 10,000 lumens from 100 watts of power. The 5000K daylight color temperature renders true-to-life color so crews can see what they're working with, even after dark. Each bulb is IP65 waterproof rated, keeping it working through heavy rain and storms, and the whole set is ETL listed for safety on commercial sites. Built-in hanging hooks let you string the lights along scaffolding, fencing, or beams in minutes, and sets connect end to end, link up to five together, to cover a wider parking lot, warehouse floor, or construction perimeter without extra outlets. At 7.83 lbs including hardware, one set is light enough for a single crew member to hang alone, a practical choice for factories, wharves, mines, and basements.
