Light box

[Spider_senses]

Does anyone have a sure fire method of making a moon box. Mostly I want to know about spacing for ceramic bases, and bulb wattage, to avoid dark spots and not see the source.

Linolites are good. The right spacing to avoid dark spots depends on the depth of the box (i.e. how much space there is between the lamps and the diffusion on the front - which, it goes without saying, should be heavy!). Also, make sure you paint the inside of the moonbox in white, to make the most of all that light that's bouncing around inside it.

 

Another way of doing it would be to use the same type of box (white-painted interior, heavy frost on cut-out), but rather than filling it with lower-wattage lamps, try a handful of 150w floods (little work-light-type units) around the edges firing into the centre - lots of light should reflect off the white surfaces, and you should get a softer, more diffuse-looking moon. You need to be careful with ventilation for this method, though, as those little puppies run quite hot.

have a look at this This forum where this was discussed in the past, lots of different ways to think about.
