In 2018 I descided to design and create my own headlamp for use in mine and cave exploration.
My old headlamp had a tendency to run out of battery fast, overheat and it lacked important safety functions for underground use.
I started searching for good alternatives designed for my use, but all I could find was expensive products.
With my background and experience in electrical engineering I thought for myself: I can make my own headlamp, just the way I want it to be.
During 2018 I desinged and made the headlamp I wanted. I even made 10 units for me and my friends. Why only make one right?
What I will show you now is the finished product, and in the future mabye the second revision/version.
Feel free to drop a comment if you like what you see, or if you have any questions.
Features:
- Up to 1200 lumens on HIGH
- Emergency light (up to 50 lumen) for low power use, or for power saving
- UV light (left reflector)
- RGB (right refelctor)
- Battery monitoring and 5x battery LEDs
- Standby LED (this will give up to 10 lumens for many days, even for weeks)
Hugely impressive project. Are you making more and selling them, or was this a personal project? If the cover is just polycarbonate, does it block the UV? What power source are you using?
Thanks, might make a new batch this winter or next year. Will post info on my Instagram if I make units to sell (Instagram in bio).
The UV light shines through the front acrylic glass. Could have a kind of filter on it, but it works nice without.
Using 18650 batteries in parrallel at 3,7v
Thanks!
On the underside of the PCB I have the drivers soldered on the PCB. The light sources are placed on the housing itself for cooling

Thanks, here is a few photos from our lates caving trip:
I’m a caver too.For caving without diving I prefer to use unibody headlamp they are small , lightweight,durable, ease to change battery and has enough light and runtime to work during one day.
