3V 100mA COB LED Filament 45mm – Flexible LED Light Source

The 3V 100mA COB LED Filament 45mm is a premium flexible LED light source designed for decorative lighting, Edison bulb restoration, DIY electronics, creative lighting projects, and custom lamp designs. Available in multiple vibrant colors, it delivers bright, uniform illumination with excellent energy efficiency and low power consumption.

At Voltros.in, we provide high-quality LED filaments that produce a smooth 360° lighting effect, closely replicating the warm appearance of traditional Edison-style incandescent filaments while offering the reliability and efficiency of modern LED technology.

Built on a flexible polymer substrate, the filament can be gently bent to fit custom enclosures and unique lighting applications. Its advanced COB (Chip-on-Board) technology ensures consistent brightness, minimal heat generation, long operational life, and excellent performance. The solderable metal terminals make it quick and easy to integrate into DIY electronics, lighting projects, and product development.
