These are so fun and unusual. After giving them a try in a few wearable projects, I can tell you they offer a stunning light source for your projects.
These are mock Edison bulb filaments — LEDs are distributed along the length of the filament. Each end has a metal tab: the end with a hole is positive, the solid end is ground. Using a coin cell battery you can test them as soon as they arrive — just touch the positive side of the battery to the holed tab and the negative to the solid tab, and watch it glow!
Key Features
Extremely flexible — curve, twist, and shape into jewellery, garment accents, or circuit highlights without breaking
Mimics vintage Edison filaments but runs cool and efficient at 3 V DC — ideal for coin cell or battery-powered builds
Simple polarity makes them beginner-friendly for sewable projects using conductive thread or snaps
Works great woven into wearables, backlit into OLED housings, or breadboarded into prototypes
