Bi-Pin Base Miniature Light Bulbs

These bulbs are small, but very bright, so they're often used in flashlights and optical instruments such as projectors and microscopes. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.
