After eight years of sailing and cruising the world, I had a terrible accident due to improper lighting not being available…. with a marine engineering background decided there should be a better affordable product! There’s nothing worse than getting products that are designed by people who have never been in the field. I have been a 14 year full-time live aboard cruiser traveling many parts of the world at this point in my life and have over 20 years marine engineering experience. This is the absolute best quality and most affordable light you will find anywhere in the world for a vessel up to 7 m. Please check out the website and other customers reviews for more information.
