2V 5M (5-meter) version. COB stands for Chip on Board technology, where multiple LED chips are mounted directly onto a single circuit board, creating a continuous and uniform line of light without visible individual LED dots. Key features and description: Seamless Illumination: COB LED strips eliminate the "dot effect" often seen in traditional LED strips, providing a smooth, continuous glow, making them ideal for applications where the light source might be visible or reflected. Voltage and Length: The label indicates it operates on 12V DC, suitable for various applications, including automotive lighting or shorter indoor runs, and comes in a 5-meter length.
