They are either compact fluorescent light bulbs, or low voltage halogen light bulbs. Both are relatively long lived, at 15,000-30,000 hours. You can buy them for anywhere from $5.00 up to $20.00 depending on wattage and life. You can buy them at most lighting stores these days, as well as most mega hardware stores like Eagle, Home Base, etc. If you can't find a place that sells them, contact the conservation office at your electric utility. They usually can point you to a local supplier. A cheap way to make normal incandescent bulbs last a long time is to buy bulbs made for 130-135 volts, and run them on your 110-120 volt wiring. Since they are burning at 90% or less of capacity, you can increase the life of the bulb by as much as ten times. However, you will burn more energy for the amount of light you do produce than you would with a shorter life normal voltage bulb, so there is a trade off....
