I have used distances of from 0.5 cm to as much as 5 cm. Remember the inverse
square law of radiation. If you double the distance- you get 1/4 the intensiy,
for example. As to the diffuser- the light from coated bulbs is already
diffused and the bulbs are, or should be, very close together. I doubt
that additional diffusion would help and it could hurt since glass and some
plastics absorb ultraviolet light (especially short wavelength UV).
