More Green light

Well the thought of leaving our Spirit sitting idle is a bit
disheartening by itself, but the light output shuts off very
quickly (6 secs.?) and the image stays in the store
indefinitely.  I'll point to Seamus' quote about the unpotential
of Spirit based film damage:

I recently noticed a small flicker problem on my Spirit #43. It
was due to having three layers of black Fagal stockings over the
objective lens assembly. A 15 minute bulb change rectified the
aging bulb issue, but isn't it nice to know that you can cripple
the light path with all that diffusion garbage and still pass
rich imagery through the gate. Anyone who thinks the Spirit is
too sharp has got to see this technique.
