There was a classic explosion-proof light in the engine room. It was originally equipped with an incandescent lamp. As was done for the other lights in the boat, I wanted to convert the lamp to LED. My first effort was to use LED replacement lamps that have the usual Edison screw base, but I found the LED lights were unreliable and after a sail or two they would stop working. Looking for something more robust, I came upon these strings of LED lights that could be cut to any length.
I pulled the guts out of the old light. Then string of LEDs has an adhesive back, so mounting them was easy. I am very satisfied with the final result. The light is now much brighter than it was originally.
