Tipped Amber Edison Mazda Lightbulb

This is an amber colored, cage filament, Edison Mazda lightbulb. This is the tipped variant. This bulb is extremely hard to find. I've only seen 3 bulbs like this one listed on eBay, one of which I won recently. The one pictured sold for $78 USD. The little glass tip on top tells us that this bulb was made before 1922. Bulbs like these were commonly used for theater stage illumination. I believe the light given off by these Amber bulbs might've been considered to be too similar to the transparent types, so not many people purchased bulbs like this one. They were also expensive, as they are made of true tinted glass (not painted).

The filament style present in this bulb is called a "cage filament", and is made of an uncoiled tungsten wire. It is supported by a glass rod with several hooks on it. The usual amount of hooks is 10, but there can be many more, especially in the case of 220 volt bulbs which require a longer tungsten wire. People often find this type of filament hard to describe. It is simply a very long continuous filament, not multiple filaments as most people usually (mistakenly) say.
