Questions about diffusing LED light.
I've just built a replica arc reactor for Halloween (iron man/Tony Stark) and the light does not display as I would like. I took the diodes from a flashlight so the light is powerful enough to show through my plastic housing. I cut out the pattern to match the lights on the movie, but instead the light shows exactly where the LEDs are placed. I need all of the light I can get to show through a t-shirt, but I need more of a flood effect inside the housing than a beam. First, has anyone tried clipping or sanding the ends of an LED? Do you believe this would adequately diffuse my light without losing too much intensity? Second, can you recommend a better material to diffuse the light such as a specific type of foam? This is my first project to use LEDs so I have no experience. Thanks for your thoughts.
