Halogen systems may appear to be old fashioned but they offer a very good money/ performance value. So why is the Passubio XC better than other halogen lights? We have spent many years on improving and maximizing the efficiency of our halogen bulbs. We ennoble them in several ways including a sand blasted tip to improve light distribution by eliminating black spots. Actually no machine finalizes the beam pattern, it is one of our employees adjusting the bulb in the reflector. The Passubio XC comes with our 16W HP 18° krypton bulb but we developed a wide range of special bulbs for certain demands to customize your light. The hard-coated glass reflectors we are using have a much higher reflection efficiency than aluminium reflectors, we therefore use glass reflectors only. The short solid spiral of a 7.2.V bulb guarantees a maximum of security regarding mechanical defects during operation. Our PCS 3.3 switch makes sure you get a white beam over the whole runtime, several power settings and a 2 stage low battery warning. The Passubio XC is ideal for all type of riding including commuting, winter road training and mountain biking. People who need more light and runtime will choose the Nightmare Pro. ** Please email for frequent sale price ** THANK YOU
