Hi Paul
I'm still researching the design for my Tak Mewlon light box and I haven't come across anything yet. I might look at those 3mm super bright LEDs if their emission spectrum matches daylight and if I can somehow modify their narrow beam to get a wider more evenly illuminated spread.
I am thinking of fitting an aluminium plate that has been sanded using an orbital sander with fine sand paper at the bottom end of the light box, as I read somewhere that this will produce Lambertian Scattering, which should produce a more evenly illuminated reflection back down the light box into the opaque Perspex.
Cheers
Dennis
