This flexible LED filament is made from dozens of tiny LED diodes bonded to a flexible printed circuit backing and coated in silicone for protection. It gives a fairly uniform glow around the filament, with the rear mesh visible if viewed up close.

The LEDs are arranged in parallel, so it only needs around 3V to light up. Adafruit recommends using a current-limiting resistor and keeping current to a maximum of 50mA.

Both contacts are on one end for easier installation in small builds. Connect 3V to the contacts, with the anode positive on the metal end with the small hole; if it does not light immediately, reverse the connection. As it behaves like a long LED, it can also be PWM dimmed easily.

Specifications:

Operating voltage: ~3V
Recommended maximum current: 50mA
Length: 25mm
Contact style: Single-ended, with two contacts on one end
Construction: Micro LED diodes bonded on a flexible printed circuit backing
Coating: Silicone protection
Datasheet: Refer to the manufacturer's datasheet

Great for miniature sets, dioramas, dollhouses and other compact lighting projects where a small flexible glowing element is useful.

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.
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.
