Those appear to be bulbs for **projectors** ... as in "Slide Projector" or
"Movie Projector."

I bought a couple of GE 250 watt Photoflood bulbs for my light box and I
love
the natural color of them. They have none of that yellow/orange cast
that
regular bulbs have. However, they are too bright and they only have a
max
life
of around 3 hours. Can someone recommend a blub that casts the same type
of
color from 100 to 200 watts?
GE makes that bulb in many different wattages. here is a link (as an
example)
that breaks out all the wattages and if there is photo bulbs available.

I am in no way endorsing this company.. simply using thier page as an
example
of bulbs available.
