Could anyone post some pictures of a high powered LED light trying to shine through some of the water resistant foam board? Is it possible to build a night flier with that stuff? I have always wanted to make an interior illuminated airplane, but I would prefer to use the stronger water resistant stuff. I also have alterior motives as the pictures will help me determine if the new foam board will be compatible with a separate project I am working on. Please also provide some measure of how bright of a light source it is. I can't justify buying a whole box just to do this test my self.
