	Hi LU's -

	Sorry! "... some magazine ..." This sounds like rumor.
	Or the people running the magazine should go back to
	publishing. I can't believe that this is true!

	The only way that could be true is if the fan is causing
	excessive vibrations of the (unlit) filament. If this
	projector causes that, it shows poor engineering. Lousy
	design of the fan, its mounting, the mounting of the bulb
	and fragility of the bulb itself.

	If true, purchase of this projector should not even be
	considered by someone who shoots with a Leica!
