LEDs come in many different shapes and sizes. You may have already seen them in those “fake” Edison light bulbs that use an LED filament instead of actual wire filaments.
Inside the filament, there is a row of tiny LEDs covered with a flexible material. They operate on 3V and are super bright.
This lamp uses yellow LEDs and works with a 5V wall adapter. The main body of the lamp is made of brass and copper tubes.
The designer has also incorporated a dimmer module that also functions as an on/off switch.
