Features of RGBW Diffused LED Light Box Bar
1. Brilliant RGBW Lighting with SMD5050 LEDs
The DF90 RGBW Series uses premium SMD5050 RGBW LEDs, combining red, green, blue and white LEDs in one lighting solution. It delivers vivid colors together with high-quality white illumination, making it ideal for commercial light boxes, architectural displays and dynamic signage.
2. 160° Wide Beam for Smooth and Uniform Illumination
Featuring a 160° wide beam angle, the LED bars provide even light distribution across the entire light box surface. The optical design minimizes hotspots and shadow areas, producing bright and professional-looking illuminated graphics.
3. Rigid Aluminum PCB for Excellent Thermal Performance
Built on a durable aluminum PCB, the DF90 RGBW light bar offers efficient heat dissipation and improved structural stability. Better thermal management helps maintain consistent brightness and extends the operating life of the LEDs in demanding commercial environments.
4. Flexible Cutting for Custom Light Box Sizes
Each light bar supports cutting every 3 LEDs, allowing manufacturers to adapt the lighting layout for different light box dimensions while reducing material waste and simplifying installation.

RGBW Diffused LED Light Box Bar Wiring Diagram & Installation Guide
1. The outlet wire of the diffuse reflection terminal connect board is 18AWG, and the Max current is 10A;
2. When the terminal connect board of diffuse reflection has a single outlet connected to the power supply (DC12V), a maximum of 10PCS LED bar with 24LEDs can be connected;

Noted:
1. The terminal connect board of Diffuse light bar, as connection layout; The power exceeds the load, an additional main line is required to connect to the power supply.
2. The distance of connect on terminal connect board is 5cm, and the Light bar can be installed in multiples of 5cm.
3. To prevent the LED strip from lifting or peeling, glue is needed for proper fixation; the adhesive backing only serves as an auxiliary fixing method.(Special attention)
Recommended Applications for RGBW Diffused LED Light Box Bar
1. Retail Stores and Brand Displays
