[simpits-tech] Projector question

[Rob Hommel]

Sean put a multimeter on a good bulb and you have the question answered.
Believe it or not they do have a resistance. You may also use Ohms law to
determine the resistance if you are so inclined. Stop by the place in which
you purchase bulbs for the thing and look at the specs for it should give
you a bulb wattage and you should be aware of the local electric supplied.
Take a look at http://www.bulbman.com and see if the information you are
needing is to be found there. I used to purchase from them years ago.

Keep 'em Flying
