The Profoto NarrowBeam Reflector creates an intense, concentrated beam of light when used with a ProHead or Acute/D4 head. Many photographers use it to project light over long distances or when they need the maximum possible power. It provides an extreme focal point and dramatic light fall-off with a striking effect. The NarrowBeam Reflector is not recommended for Profoto flat front lights. The reflector includes Profoto unique zoom function that allows you to shape the light by simply sliding the reflector back and forth on your head. Light spread is adjustable from 25 to 70° on the ProHead. Maximum light output at 2 m with 2400 Ws at ISO100 is f/128.1 (on ProHead). Compatible with several optional accessories including grids, barndoors and ProTube.
