Top-Flanged-Base Miniature Light Bulbs

Pointed Bulb, Incandescent | Pointed Bulb, Halogen | Pointed Bulb, Krypton |
Use these bulbs in small instruments, such as microscopes, projectors, and inspection lights. A flange holds the bulb at a fixed depth to keep light properly focused. Also known as miniature flange-base bulbs, they’re sized to fit tight spaces. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.
Krypton—Produce a bright light, such as a camera flash. They last longer than halogen and incandescent bulbs.
