Each unit is rigorously tested for optimal performance. - Versatile Applications : Ideal for both indoor and outdoor use. Perfect for job sites, construction zones, mine caves, attics, basements, storage areas, stairwells, parking lots, outdoor markets, marinas, or any location needing additional lighting.
