Mazda 60w 220v tantalum filament

Mazda 60w 220v tantalum filament

Click to view full size image

Here you can see a tantalum filament. I love to see this filament !!! It has 220v very rare since it comes from the United States. On the base it has patent 1904 marking. It is very difficult to find this type of wrinkled filament. It seems to stretch when hot and contract when cold.

The tantalum filament lamps were short lived, because at the same year of their commercialization, the tungsten filament lamp being invented.

thanks for the information. then it has really assumed a null advance. however it appears that tantalum is more efficient than tungsten and also more brittle. You don't see many lamps of this type for sale. It is a shame because they are very beautiful on.

What is the color temperature of tantalum filament lamp compared to vacuum tungsten filament lamp? Tungsten have higher melting point, so it can run hotter than tantalum.

You can still find the modern Tungsten drawn filament on antique reproduction bulbs out there

Pretty, please no more Chinese failure.

I do not know the color temperature. The only thing I can say is that it is more efficient and gives a greater amount of light with less watts of power than a similar tunsten. there are still reproductions. I am personally against counterfeiting. but I see it well for other people to enjoy. like the original there is no
