My measurements showed that the halogen bulbs actually
resulted in less lumens in both my 116 and 716 stereo
projectors.  The difference was enough to convince me
to stick with the original CZX bulbs.  Tom Hubin gave
an explanation relating to the size of the bulb filament
and the condenser lenses in these projectors.
