This Blue flexible LED filament COB light (128mm) is a compact, low-voltage lighting solution designed for DIY LED lighting, decorative illumination, and electronics projects. Built using advanced COB (Chip-On-Board) LED filament technology, it produces smooth, uniform, dot-free blue light output with consistent brightness and high energy efficiency.
With a slim 2mm diameter LED filament and 128mm length, this flexible COB LED filament strip is ideal for linear lighting, accent highlights, and custom lighting layouts. The bendable LED filament construction allows gentle shaping and easy installation in tight or curved spaces, making it perfect for custom lamps, signage lighting, model making, display accents, and creative lighting designs.
Operating on 3V DC low voltage, this low-power LED filament light is suitable for battery-powered LED projects, Arduino and microcontroller lighting, wearable LED builds, and portable decorative applications. The vivid blue glow is well suited for indicator lighting, theme lighting, artistic effects, and modern accent illumination.
