USB Filament is an USB powered filament LED lamp. Just stick into any regular USB port and enjoy the soft glow of the filament LED.
Just like candles, Filament LEDs emit soft, warm light. Filament LEDs are energy efficient - USB Filament drives the filament with 0.5W of power and it is bright enough to read a book. USB powered means you can use any USB phone chargers to instantly create rechargeable LED lanterns and more. USB Filament has voltage booster circuit to generate the 70V needed to light the filament LED.
USB Filament kit contains only through-hole components. Assembly/soldering is very straightforward and beginner friendly.
