Longevity and reasonable maintenance costs account for the success of tungsten halogen lamps as light sources for demanding airfield lighting applications. OSRAM tungsten halogen lamps provide an instant and constant output over the long lifetime. They are dimmable and allow flicker-free operation. Moreover, their small bulb dimensions and high luminance enable compact designs of airfield lights. OSRAM offers tungsten halogen lamps from 30 to 200 W, either with or without reflector. Due to their IR radiation, they can be used even in extreme weather conditions such as low temperatures and snow.
