Diffusing white LED's. I need high intensity white light but with little or no projection.

I am trying to have as bright a light as possible from 2 white LED's but with as little light projection as possible. So far I have found a small bit of a plastic shopping bag does well but the light isn't bright enough. Any suggestions would be greatly appreciated. Many thanks

Someone wrote an Instructable on diffusing LED lights... You can find it on the right ----->

They simply used some fine grit sandpaper, which seems to work fairly well.

Thanks for the answers. I will try both sandpaper and the frosted perspex idea.
Thanks again
Try a sheet of frosted perspex, and project the LEDs into the EDGE of the sheet.

You can't have "bright as possible" and "little light projection as possible" are exact opposites.

If you are just after bright light in all directions, try roughening the LEDs with sandpaper.
