The 5900 Series Multifunction Reflector-Facing Technology LED Light Bars feature high-performance 8W LEDs and utilize the latest RFT (Reflector Facing Technology) optics, which provide an impressive 95% light transmittance and optimize LED efficacy to maximize light coverage. The patent-pending design features an ultra-slim body (less than 2” tall) and standard dual heavy-duty mounting brackets to provide the user with options to mount these bars in a variety of applications where other LED light bars may not work. Other included technology, such as Electronic Thermal Management (ETM), is an onboard module that monitors PCB temperatures and regulates the current if the LEDs to prevent the possibility of LED overheating. This combined with over/under voltage protection, wide voltage input range (9V-36V), reverse polarity protection, high-current Deutsch DT Connectors, and IP68/9 Ingress Protection make this a very robust and high-quality system with long-term reliability. $169.95
