Project Info

We're cutting light bulbs! (<--- Not something that I ever thought I'd type out.)


I had a collection of large industrial light bulbs that no longer worked, and I needed a project to repurpose them into something new. 

My original idea was to install a small LED bulb inside the light by drilling a hole in the base and threading an LED through the hole and let it hang inside the larger bulb. But after closer inspection, I found that cutting off the base and glass at one time would probably be a safer choice.

Not sure if that was the right decision.

You can see in the video that the cutting of the bulb bases was somewhat successful. BUT IT WAS DANGEROUS. You've got to be careful if you want to try this project as the bulb is extremely fragile without a spinning blade interacting with it. The smaller bulb size was easier to hold and easier to handle while cutting. The larger bulbs were more fragile and just didn't cooperate well with the saw. And the reason that I used this tile saw was because of the diamond blade that I know could cut through metal and glass all at once. Overall, if you try a project like this, keep your attention focused on the cutting at all times and don't take anything for granted, including your perceived safety.

We're cutting light bulbs, people. Be smart and take your time.

Some insights on this project:

1. Cutting light bulbs is dangerous work. Keep your mind focused at all times. That's my warning to you.

2. I was lucky to find the meter socket hub that fit the base of the smaller bulb size. It was a great base for the bulb in that it's sturdy and can be easily mounted. I'm not sure what type of base I'd like to use for the larger bulb but it needs to be solid and large enough to cover the ragged glass edge.

3. And these new slim LED bulbs are great! This is the same type of bulb that I used in the Robot Lamp (video here) and I've been very happy with the performance of this bulb.


4. For the switch, you can use whatever you like. I wanted the rotary style switch here just for aesthetics, and this one is not dimmable. Just an easy on/off.

5. I used Mahogany for the lamp base for no particular reason. And the finish is intended to be rustic and rough, to look worn out with some age. I thought that style would pair well with the patina of the metal and the style of the bulb/LED bulb. Use what you like, use what you have.

6. If you're uncomfortable working with electricity, get the advice and skills of a professional electrician.

Hopefully this gives you some insight on how to create one of these for yourself. Please like and subscribe to the YouTube channel and share the video with your friends. Every little like and share helps keep me in the shop.
