Miniature Light Bulbs

An incandescent light bulb is an electric light with a wire filament heated to such a high temperature that it glows with visible light.

The filament is protected from oxidation with a glass or fused quartz bulb that is filled with inert gas or a vacuum.

In a halogen lamp, filament is slowed by a chemical process that redeposits metal vapor onto the filament, thereby extending it's life.

Many of the products listed are stocked at Farnsworth Electronics.

There are many different shapes, colors, and sizes of light bulbs. If there's one product line we know very well, it's bulbs!

Start with finding the base type you have, then you need to know the voltage and wattage or amperage of the bulb

if it doesn't have a part # listed on the bulb itself.
