Features of 4-LED SMD5050 RGB LED Backlight Module
1. Four SMD5050 RGB LEDs for Denser Color Backlighting
The YS-M42Q41 4-LED SMD5050 RGB Backlighting Module integrates four 3-in-1 RGB LEDs into one compact unit, providing a denser arrangement of RGB light sources than the three-LED version. This can be useful when a sign requires stronger color coverage from each installation point.
2. 1.44W 12V DC RGB Configuration
Operating at 12V DC with a rated power of 1.44W per module, the product fits conventional low-voltage RGB lighting systems. The defined module power also helps sign manufacturers calculate the total electrical requirement for larger installations.
3. IP65 Protection for Sign Lighting
The IP65 rating provides protection against dust and water exposure, supporting use in appropriately constructed indoor and outdoor sign lighting systems.
4. Cuttable for Custom Sign Layouts
Each module can be cut as required, allowing the lighting arrangement to follow different letter shapes, corners, curves and custom logos instead of being restricted to a fixed layout.

Recommended Applications for 4-LED SMD5050 RGB LED Backlight Module
1. RGB Backlighting for Medium-Depth Channel Letters
The YS-M42Q41 4-LED RGB Backlighting Module is designed for 8–16cm channel letters, providing multiple RGB light sources within each module. The 120° optics help direct the colored light toward the illuminated face.
2. Metal Letter Illumination
The compact rectangular shape works well inside metal letters and dimensional signage, where the available internal area may be wider rather than elongated. The four-LED layout provides several RGB lighting points within one module.
3. Decorative Commercial Signage
The product is suitable for decorative lettering and commercial displays where RGB lighting forms part of the visual design. It can create stronger color presence than conventional single-color LED backlighting.
4. Promotional Advertising Displays
