Attaching the base
8 The base of a lamp provides the electrical connection and mounting. The geometry is defined in national and international standards. There are several different types of bases. For single-ended lamps, glass, ceramic or metal bases are used. These are usually bonded to the glass bulb with special cement that has good resistance to high temperatures, moisture and thermal stress or attached mechanically. A cement-free connection is used for special applications.
Packaging
9 After final testing, the lamps are manually or automatically packaged into boxes, depending on application. Lamps sold to retail stores are individually packaged.
