This Blue flexible LED filament COB light (300mm) is a compact, low-voltage lighting solution designed for DIY LED lighting, decorative illumination, and electronics projects. Built with advanced COB (Chip-On-Board) LED filament technology, it delivers smooth, uniform, dot-free blue light output with consistent brightness and high energy efficiency.
With a slim 2mm diameter LED filament and extended 300mm length, this flexible COB LED filament strip is ideal for long linear lighting runs, edge accents, 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 builds.
Operating at 3V DC low voltage, this low-power LED filament light is suitable for battery-powered LED projects, Arduino and microcontroller lighting, wearable LED designs, and portable decorative applications. The vivid blue glow is well suited for indicator lighting, themed décor, artistic effects, and modern accent illumination.
