I like the idea of light with out battery drain but I dont want my project to look like a "lumpy potato" when I'm done, so I need opinions. If you could, would you put in a few well placed deck prysms?
They can be really hard to keep sealed. That said, they can also be really nice. I once had a pair in a v-berth that were massive solid crystal grapefruit juicers installed upside down. They refracted rainbow colored sunbeams all over the inside of the forepeak, very nice. Had to be resealed yearly, nothing sticks to crystal.
