Grooved Base Miniature Light Bulbs
LED
Incandescent
These bulbs are sized to fit tight spaces such as signs, control panels, indicators, and flashlights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration.
Incandescent bulbs are traditional light bulbs.
