Ultra-Bright: 1500 LEDs on this 5M COB LED Strip Lights(300LEDs/m), which make the emitting units unprecedentedly close to each other, and create super even lighting performance. Compared to the SMD 2835: 1 chip on board, or 5050: 3 chips on board, a COB (Chip on Board) LED light has multiple chips on the same PCB (Printed Circuit Board) * No More Dark Spots or Visible Dots: Low power, higher light efficiency, higher colour rendering index (90+). 180 degrees beam angle design for 50% wider lighting, multiple chips on board for uniform illumination, NO MORE worries about dark spot! * Safe for Daily Use: Compared to regular LED strip lights, the light is soft and uniform, which is better for your eyes.
