"The RAK LED Modules are manufactured with hand picked diodes ensuring consistent color matching. The interior modules are thinner in design, which allows them to be used in a wide variety of applications. The LED Modules are designed to consistently reproduce any 4:4:4 RGB color resulting in optimum resolution regardless of content. A revolutionary auto-configuration design, which automatically assigns the correct address to each module , eliminates the need to wire modules or set DIP switches in a specific order. This feature enables quick and efficient installations as well as a new level of ease in service. Front or Rear access option based on frame and cabinet structure provides simplicity in installation and service. Any of our modules can be switched out in less than 90 seconds - with no specialized tools. High efficiency power converters reduce overall power consumption and heat loss in the driver chips. Total power consumption is reduced while minimizing power supply failures. A Five-level weather-proofing protects the modules in the harshest environments while using outdoors. High refresh rates allow high speed motion graphics and gradations to appear smooth and effortless, ensuring your message appears with the rich lustre intended."
