You are arguing about the replacement cost of a globe for a Ritchie
SP5 Globemaster. normal lifespan before showing UV damage is at least
ten years

It's far longer than 10 years if you cover it when not in use. I've seen
discolored cards and yellowed plastic on some. I'll keep mine covered when not
in use, thank you. I feel confident that Suzanne and I can get the cover off if
a "sudden" fog drops on us.
