COB stands for Chip on Board, meaning the LED diodes are built directly into the Printed circuit board. The main advantage of this technology is that there is no visible spotting, even when used in more shallow LED profiles and spaces, this ensures the finished installation will present a seamless uninterrupted finish.COB technology also generates less heat, which in turn makes it more efficient, makes the tape last longer and maintain a high-level performance over a longer period of time. This makes our COB Continuous LED Tape perfect for high-end professional and commercial installations. The high build quality and components will assure long lasting performance and reliability.
