Totally waterproof LED light is an affordable, exciting way to light your dock above or below the waterline. A broad floodlight effect is created by the engineered optics of the convex light face. 600-lumen light has a brighter beam than most models available. Because of its low heat output, this light also works well on transoms, trim tabs, and T-tops. 100,000-hour life. Stainless steel hardware included. 3-1/2" x 1-1/2".
