Attwood is proud to introduce one of the most innovative navigational lighting products available today. Achieving 3NM of 360° visibility while drawing a fraction of the power of traditional incandescent lights, Attwood's 3NM LED Masthead/Anchor light is one of the first of its kind. Constructed of corrosion resistant composites with stainless steel accents, this product was designed for the harsh coastal marine environment. All lights come equipped with a durable folding base cast from Attwood's blend of enhanced 316 stainless steel alloy. For use on boats up to 65.6' (20M)Attwood's proprietary optics design draws only 1.8W at 12VDC - the lowest power draw of any 2-mile all-round light on the market today! Lights are rated for 50,000+ hours of use and feature a 10 year warranty.
