The Zambezi underwater light is tough, tenacious, and built to survive completely submerged in salt or fresh water (Zambezi's wire and seal is the result of more than 70,000 hours of ingress and long-term permeability testing). Can be operated above or below water with no long term detrimental effects. Perfect for smaller pontoons and skiffs, Zambezi Mini is small, easy to mount, easy on the wallet, yet packs a visual punch. 3-Screw mounting footprint.
