Dental Equipment

I went to the dentist today (hooray - no cavities!) and while staring at the ceiling began to wonder how much the overhead lights cost. I should have asked my dentist, but I did not think it was appropriate (especially since she could break one of my teeth if she was offended by the question). Anyway, I found the company's website and a description of the ceiling-mount light, but the site did not include any prices. I have had little luck while continuing to search the internet (yes, this is how I have been spending my day off), so I thought I would ask to see if anyone knows. So, does anyone know?
