This black True Blue D25 2500W HMI Fresnel from ARRI is another example of their completely redesigned True Blue series. The 10" Fresnel with a beam angle variable from 6-59° is protected with stainless steel mesh. Pressure die-cast and extruded aluminum alloy components make the D25 lighter without sacrificing strength while improving corrosion resistance.
Since front heavy accessories like large softboxes are routinely used, ARRI has incorporated a sliding stirrup that allows you to find the light's center of gravity based on the weight of the accessory. A disc brake-type tilt-lock secures the head at the chosen angle with minimal force. Cross-cooling channels the air through the housing so effectively the D25 can be used at almost any angle. Accessory brackets, a problem in the past, are now adjustable to hold 2 or 4 scrims or filter frames to eliminate light leaks. You can also use the D25 rain or shine thanks to improved IP23-rated weather protection.
