LED TV backlight strips Features:

Precise Fit, Ready to Install

These TV light strips (model LED55D8A/B-ZC14DFG-01) are engineered specifically for 55-inch models such as Haier LS55AL88A72 and Konka LED55R80. The 553mm length aligns perfectly with the original backlight layout, and the connectors match the factory specifications for true plug-and-play installation—no rewiring or modifications needed. Fully compliant with IEC 62717 compatibility standards, they prevent issues like mismatched parts, flickering, or display distortion. The complete 14-piece set provides full screen coverage, making replacement straightforward even for first-time users.

High Brightness and Uniform Illumination

These LED TV backlight strips feature an 8-LED layout powered by a stable 3V driver, delivering a luminous efficiency of 220 lm/W (CE optical safety certified). With a 120° beam angle and a flicker-free performance above 3000Hz, they ensure smooth, consistent lighting across the entire screen. Light uniformity deviation is tested within ±4%, and color rendering reaches 81%, eliminating dark edges, hotspots, and uneven brightness. The result is a comfortable, eye-friendly viewing experience suitable for long watching sessions.

Efficient Heat Dissipation and Long Lifespan

The strips use a high-conductivity aluminum substrate with a tested thermal conductivity of 2.2 W/m·K—significantly higher than the industry baseline. The widened and reinforced heat dissipation design keeps LED temperatures below 60°C during operation, with all insulation materials meeting UL 94V-0 flame-retardant standards. The imported LED package provides strong adhesion (3.2N per IPC-TM-650 testing), offering excellent durability against drops and oxidation. Each production batch undergoes a 72-hour temperature cycling test (-20°C to 75°C), ensuring a long operational lifespan of over 50,000 hours.

Reliable Quality and Stable Performance

Quality control is carried out across every step of production: aluminum purity (≥99.5%) meets GB/T 3190-2020 standards, LED brightness is individually calibrated, and each finished strip undergoes full power-on stability testing. Standardized manufacturing limits batch variation to within ±2%, preventing issues like uneven brightness, inconsistent color temperature, or premature failure. Designed to fit Popular, Haier, and other major brands, these strips provide a dependable, cost-effective replacement solution.

Dependable After-Sales Support

Beyond strong performance and compatibility, these TV light strips come with a full one-year warranty covering issues such as brightness drop, connector instability, or non-impact-related failures. After-sales service is handled directly by the factory with response times within 24 hours, giving users a secure and worry-free experience.
