First off hello..This is my first post here. I did some looking around and it looks like some of you may be able to help me? A little background of my project. I'm building 2 sets of transom lights for my boat. The first set is 24 3watt Ebay LED's in each light. Each string will run off a Flexblock at 48v in series, 12 LED's. The second set is 4 Lexeon M 12watt each led. My question isn't about powering. I'm using the following light enclosure. It's 6063 Aluminum. These lights will be in saltwater. I embedded the LED's in thermal epoxy then attached the rectangle tube to the u channel where the lights are embedded with thermal epoxy to transfer the heat. Water will run behind the led to cool. That is my theory..I am going to prime and paint the aluminum to protect it. It may take away from the heat transfer, but I have to protect it somehow.
NOW....I'm trying to figure out how to waterproof the LED's. I purchased some MG encapsulating epoxy and was thinking of filling the channel shown. I'm afraid of the epoxy cracking. Or water leaking in where I would drill the wire to power the LED. Will the encapsulation fill the void and keep out the water. If I was able to machine and install a lens I would, but I can't. Any suggestions are welcome. Thank you
