I converted the entire boat to LED fixtures a couple of years ago. I changed the navigation lights 1st then all the interior and accent lighting. With over 40 fixtures my current draw went from 20 plus amps to 3.5 amps (every light on). Colors are blue for the salon, blue and or white for the cockpit, white and or red for the helm and gooseneck reading lights.
I find the lighting to be brighter especially the navigation lights. The blue accent lighting is very nice looking. The red lighting is used up at the helm when running at night.
