Looks like coating is applied thin making the zigzag filament visible.

Long live the great old 20th century quality in electrical & lighting products!

I only noticed that you could see the filament on the blue and yellow Tungsram ones I have. It was not noticeable on the red, green or orange ones.

This is the IR penetrating the powder and the camera seeing it. I once photogtaphed a Philips PF-710 or 712 darkroom lamp, the red one, the 5WR filament was clearly vosible to the camera, but not to the eye.

Manufactured articles should be made to be used, not made to be sold!

GC, the filament on the blue and yellow Tungsram's That I have can definitely be seen with the naked eye.

Andrew, that sounds like how cameras can also see the IR light that comes from the LED's that are in IR remotes for audio/ video,equipment. I had played around in the past taking the TV remote and aiming into an camcorder lens and seeing the rapid flashing from the IR LED's in the remote on the view finder screen.

Long live the great old 20th century quality in electrical & lighting products!

Astronomers use the effect too...they a watching some massive stars orbit a black hole at our galactic centre, the first direct evidence of the existence of a black hole. The stars can`t be seen at visible wavelengths because of intervening interstellar dust, but at about 8000nm, they can see straight through.

Rapidstart: If it is visible to the eye too, then it is simply a very thin dusting of powder.
