Ah, thanks. :-)
Meanwhile, I came upon two more questions:
1.
I am using one light source, a flat energy-saving fluorescent light bulb on top of the box. To reflect the light best from the ceiling above the light bulb, should the ceiling be a mirror, or aluminum foil? What's better in reflecting light back downwards?
2.
There will be a glass plate between light bulb and main box, to avoid heat emission from the light bulb. Should that separating glass plate be fully transparent (normal) glass, or milky glass, or roughened glass?
Thanks.
