This skull-shaped LED filament uses COB (Chip-on-Board) technology — dozens of micro LED diodes bonded to a rigid metal backing and coated in silicone — to produce a warm, uniform glow similar to Edison-style LED bulbs. The LEDs are positioned on one side, with a subtle glow visible through the ultra-thin PCB substrate on the back.

Simply connect 3 V across the two terminals (cathode marked with "−" on the PCB). The LEDs are wired in parallel and support PWM dimming for adjustable brightness. Use a current-limiting resistor to keep total current at or below 100 mA.
