The ZB100F is a portable, 100 watt black light that produces longwave ultraviolet light at 365 nanometers. The polycarbonate Air-Flo™ bezel allows air to cool the lens in the rest position, and helps keep operators' hands away from the lens during use, protecting them from burns. The cord-through-handle design reduces operator fatigue, improves balance and provides greater safety. Its tough aluminium housing withstands rugged use and the recessed lens design protects the lens and bulb from damage.
