These non-flexible LED filaments are often seen in 'Edison-like' LED bulbs, arranged in different patterns to give a bright warm lighting effect. They're made of dozens of micro LED diodes that are bonded together on a stiff metal backing, then coated in silicone for protection. Since the LEDs are in parallel, you only need 3V to light 'em up - we recommend current limiting with a resistor to let max 50mA through.
Please note, these are NOT flexible! However, they have a nice uniform glow all the way around and really do an excellent job of mimicking a tungsten-like filament.
Comes three per pack. Add some mini neon bling to your miniature sets, dioramas, dollhouses, mini-verses, what have you! Because they're just a 'big long LED' you can PWM dim them easily.
Simply power up with 3V by connect to both ends - the anode should be the metal end with a little hole in it. If it doesn't immediately light up, try connecting the other way around, no biggie.
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.
- 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.
