spectrophotometers use light bulbs as their source.  light bulbs fade and burn out over time, don't they?

Yes, spectrophotometers depend on some type of lamp, which can be either thrown out or re-used. For instance, a single-beam spectrophotometer, which can use a tungsten or deuterium lamp, depending on the wavelength region that you're interested in.
