It's not a dumb question. The Xenon-arc bulb in my JVC G1000 cost $350, although it was included partially used. It's a miniature version of the same bulb used in 35mm multiplex cinema projectors.
My older projector: www.marky.com/hometheater
Although modern projectors sometimes use cheaper bulbs that cost less than $100, but they still cost a lot, such as "$85.00 plus tax". But many brands have bulbs that cost a couple hundred dollars even today.
Now, if you were commenting the "dumb question" because Tom already posted....
