In some articles it has already been pointed out that old light bulbs can easily get a new “lamp life”. For this, however, the filament, its holder and parts of the threaded socket must be removed in almost all cases.
How you can do this is described in the following article.
Hints for our lovely english readers: Basically, many of the articles on Nerdiy.de are translations from the original german articles. Therefore, it may happen here and there that some illustrations are not available in english and that some translations are weird/strange/full of mistakes or generally totaly wrong. So if you find some obvious (or also not obvious) mistakes don't hesitate to leave us a hint about that in the comment section.
Also please don't get confused, that instead of a "dot" often a "comma" is used as decimal separator. 🙂
I know the following hints are always a bit annoying and seem unnecessary. But unfortunately, many people who knew it "better" from carelessness lost their eyes, fingers or other things or hurt themselves. In comparison, a loss of data is almost not worth mentioning, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Even the coolest project is worth no injury or other annoyance. https://www.nerdiy.de/en/sicherheitshinweise/

In the following list you will find all the parts you need to implement this article.

Especially at work as this you must pay even more attention to safety! It is very likely that one or perhaps several bulbs will break during the first attempts. That’s why enough thick gloves, a garment that covers the arms and protective goggles are essential for the work.
Please be conscientious and careful at work and do not join the ranks of people today who say, “Oh, I should have spent five seconds making safety arrangements”.
Remove foot contact
The only sensible way into the vitreous body of an incandescent lamp is via the screw contact. This also contains the two contacts via which the light bulb energy is supplied. These are called ring contact and foot contact. Of these two, the foot contact is relatively easy to remove, allowing access to the vitreous.
Remove the lower part of the glass bulb
After the foot contact is removed, it is relatively easy to approach the lower end of the glass bulb.
Piercing through the glass body
Now comes the most critical part. Now you have to break a first hole in the glass body with a screwdriver.
After you have pierced the glass body, you can now enlarge this hole with a screwdriver.
Remove the last pieces of broken glass.
Incidentally, this method also works with other types of incandescent lamps. 🙂
I hope everything worked as described. If not or you have any other questions or suggestions, please let me know in the comments. Also, ideas for new projects are always welcome. 🙂
P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you appreciate it that I share these information with you, I would be happy about a small donation to the coffee box. 🙂
