A screw base is a threaded, cylindrical lamp base with a single contact on the bottom that screws into a socket to hold the lamp and complete its electrical connection.
A screw base is a common type of lamp base shaped as a threaded cylinder with a single contact at the bottom. The threaded portion screws into a matching socket, holding the lamp securely in place, while the bottom contact and the threaded shell complete the electrical connection that powers the lamp. This familiar base design is used across a wide range of lamps.
By combining mechanical attachment and electrical contact in a simple threaded form, the screw base makes lamps easy to install and replace. The size of the screw base is matched to the lamp and socket, and reliable contact at the base is important to stable operation.
In commercial and industrial lighting, screw-base lamps are widely used, and the sockets serving them connect through power wiring matched to the lamp's voltage and current. Reliable connections at the base support dependable lighting.
Because reliable contact at the base is important to stable operation, the sockets serving screw-base lamps connect through power wiring matched to the lamp's voltage and current, so the lamp installs easily and operates dependably in commercial and industrial lighting.
