Shannon and Nancy: Perhaps I was not very precise with what I wrote. I
try to locate the lighting unit(s), whatever type, in a separate light
box, externally ventilated that sits on top of or on rare occasions
below the display case. The separating medium can be frosted glass or
plywood with a small glazed hole if those small halogen lamps are used.
Access is external. The finish of whatever encloses the light box can be
easily matched. With such a method, I had not encountered glare.
I am very interested in fiber optics, but I have to admit that I have
not used it, although I have investigated this method for a display of
railway kerosene lamps. I wanted to get each lamp to light up and
flicker in a sequence to coincide with a pre-recorded commentary dealing
with the various types. That exhibit for a major project is on hold,
until the funding position is sorted out.
Most of my information for fiber optics came from
