Wire-Terminal-Base Miniature Light Bulbs

Connect these bulbs to a power source through a panel using the wire terminals. They fit into tight spaces in equipment and electronic assemblies. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Infrared LED

Infrared LED bulbs are often used in night vision goggles, thermal imaging cameras, and TV remotes. Infrared bulbs produce light that is invisible to the human eye and emits more heat than incandescent light bulbs.
