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.
Key Features
- COB LED Construction – Dozens of micro diodes for warm, uniform illumination
- 3 V Operation – LEDs wired in parallel; simple two-wire connection
- PWM Dimmable – Adjust brightness with pulse-width modulation
- Rigid Design – Non-flexible metal-backed PCB with silicone coating
- Subtle Rear Glow – Ultra-thin substrate allows light through both sides
Specifications
- Type – COB LED filament (skull shape)
- Operating Voltage – 3 V
- Max Current – 100 mA (use a current-limiting resistor)
- Dimming – PWM compatible
Ideal For
- Halloween and spooky-themed displays
- Miniatures, dioramas, and dollhouses
- Decorative lighting projects
- Custom lamp and lantern builds
Package Contents

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
