You just can't go to your local hardware store and expect to find a 19.2v bulb like this. I'm glad I was able to find her at Revain. It works. If it lasts as long as the original bulb, it's worth the price. But it will likely outlast the life of nickel-cadmium batteries. I know it's supply and demand, but paying $8 for a tiny lightbulb just bugs me.
