12mm | 24V | 128LEDs | 12W | 62.5cut | #4479 | 2835 C.C. High Light Efficacy High Lumen LED Strip

This 2835 high light efficacy constant current LED strips are designed with 8 LEDs per segment, enhancing their luminous efficiency. Due to the higher voltage drop management requirements of this design, we utilize a linear constant current circuit structure, effectively controlling voltage drops and achieving a high-efficiency LED strip product. The robust pure copper LED frame, combined with encapsulation using 99.99% pure gold wire of diameter greater than 1mm, minimizes damage to the LEDs in various applications.

As an integrated entity of R&D, manufacturing, and sales, DENO prioritizes efficiency and application from the initial design to the final product. One of our core objectives is to enhance the market competitiveness of our partners.
