Often called a Redhead, this Arri product is in fact a blue coloured head! It is tougher than most other redheads. With good ventilation and an inner shell, this one is also cooler to touch. The focus knob is located under the light, and therefore under the heat source; it does not get too hot. When focusing the reflector moves, not the lamp; this helps to extend the lamp life. The barndoors are mounted onto a rotating front assembly making it easy to position the barndoors
