LED technology is a new frontier. For most in the lighting industry there is a very real learning curve as we explore the intricacies, applications, limitations and potential of this amazing light source. Despite the curve, use of LED lighting for general lighting purposes is rapidly growing. Its popularity is not a mystery. LED technology is continually improving. LEDs offer long life and high efficiency, have low operating costs and are lead and mercury free. As with other types of lighting, LED lighting must meet the life safety code requirements for emergency illumination. LED fixtures serving as emergency units must, therefore, provide at least 90 minutes of emergency lighting. Fahold HM- emergency LED drivers and emergency lighting inverters allow these fixtures to meet or exceed code.
