We had a slide scanner at work used to make computer images of old projector slides. It used a pea-sized incandescent bulb to illuminate the slide for scanning.

Eventually the bulb burned out. It's then when we discovered it was soldered into place and could not be replaced. Instead of having to replace a 50-cent bulb, you had to replace the entire $100 device.
