This project by Tjiani Lucht is incredibly simple – the excellence lies in the way the idea has been executed. There are almost no fancy electronics to it, other than a step-down converter to reduce the voltage from the 15 V coming from an existing power supply to the 3 V required by the LEDs, and a switch to turn the lamp on and off.

What stands out about this build is the use of materials: instead of light bulbs, the maker has used 24 LED filaments housed in glass test-tubes, with additional brass bits to extend the LEDs further into the tubes. The electronics are housed on a piece of MDF, and the test-tubes are held together by transparent acrylic. It’s incredibly simple, but no less striking for that.
