    I decided to check the voltage supplied by the outlet in my living
room....My outlet with no load measured 114 volts and with the projector
turned on the voltage dropped to 107 volts.  This lowering of voltage will
cause a
lighting appliance to draw less current and therefore produce less light."

Bravo, Don!  Others had commented that the higher wattage bulbs didn't seem
brighter, and I wondered why.  Way to go!  My electronics teacher (one
semester, high school) would probably be shaking his head in disgust at me
for not figuring it out myself.  :)

Now I can just imagine Dr. T running out for a meter to check his
projectors, too.  Am I right, George?  You seem like the type of person who
would!  :D

Best regards,
