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 with 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.
