Features of Waterproof 3-LED White LED Module
1. 3-LED SMD2835 Configuration
The YS-MD8331 3-LED White LED Sign Module uses three SMD2835 LEDs in a compact housing, providing a practical combination of light output and installation flexibility. The three-LED arrangement is suitable for illuminated letters and light box structures where a distributed white light source is required.
2. 100–150lm Luminous Output
According to the detailed product specifications, the module delivers approximately 100–150lm per piece with a rated power of 1.2W. This output range provides a balanced solution for signage applications that need consistent illumination without using an unnecessarily large module.
3. Plastic + Aluminum Construction
The product uses a combination of plastic and aluminum materials. The aluminum component contributes to heat dissipation, while the molded plastic housing keeps the module lightweight and provides a practical structure for installation inside different types of signage.
4. 20-Module Standard String
The standard connection quantity is 20 modules per string, with a maximum series quantity of 30 modules according to the supplied specifications. This provides installers with a clear reference for module layout and power distribution when designing complete sign systems.

2. Illuminated Company Logos
For backlit logos and corporate identity signs, the compact three-LED layout provides a practical way to distribute light across individual letters and graphic elements while maintaining a relatively simple 12V installation system.
3. Commercial Interior Signage
The product can also be integrated into indoor directories, reception signage, decorative lettering and commercial display systems, particularly where low-voltage operation and different white CCT options are beneficial.
