What appears promising with Lee’s design is that it is simple and appears quite effective from the results posted so far. I don’t have the smarts to perform any mathematical modelling or light ray tracing, so I just followed the advice on several websites which had the light bouncing off the inner walls and the bottom of the bucket to “flatten” it, before finally striking the main diffuser.
Lee’s design seems to achieve this via direct illumination of the diffuser by a bank of LED’s, which certainly simplifies the design and build process in my book.
