Wire terminals allow you to connect these bulbs to a power source through a panel. These bulbs are sized to fit into tight spaces such as signs, instruments, indicators, and flashlights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

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.
