COF strips have a simple structure with FPCB, chip, and phosphor glue, making them more cost-effective, which is best suited for linear white light applications, offering cost advantages for budget-friendly lighting solutions.

COF LINEAR Series adopts the technique of flip-chip on a flexible PCB which is mainly used for white light strips, with more LEDs it emits more uniform light, and is suitable for decorative, auxiliary, and furniture lighting.
