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
- 1× Skull LED filament
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- 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.
