DIY Lighting / diffusion solution to get the most even lighting for 18"X24" ultra-thin and portable light panel?
I'm building a thin and portable, 18"X24" lightbox that needs to have super-evenly diffused light: as if it was a flat panel lcd (which I would use had I the money, though it's heavier than I would like).
What technique do you suggest I use? Will CCFL or led lights along the sides of white plexiglass work? If so does anyone have an idea how to aquire & assemble them (I've seen tutorials for laptop sized panels but not for one this large- don't know if the light will reach the central area of the panel)
Or should I just use led strips along the bottom and sides of the box under the diffuser? If so how do you suggest I spread them?
