ARRI True Blue D40 HMI 4K Fresnel Kit

The kit includes a True Blue D40 HMI 4K Fresnel Head with a variable 6.5 to 61-degree beam spread, 4-way barndoors, a filter frame, 50′ head-to-ballast cable, and a 2.5K/4K Electronic Ballast with DMX and ALF.

The 120-240 VAC ARRI Electronic 2,500/4,000W Ballast with ALF and DMX is a multi-voltage, dual wattage electronic ballast with Active Line Filter for Power Factor Correction. ALF provides a higher Power Factor resulting in more efficient power use. This is accomplished by shifting the voltage and current waveforms in phase and minimizing harmonics and spikes. ALF also minimizes the current carried back on the neutral leg of the power systems.

-Multi-voltage, quiet operation. -Dimmable, operates with 2 or 4K setting.   the D40 HMI 4000W Fresnel Head stays true to its Arri roots with its compact size, while reducing weight and maximizing light output. True Blue heads also feature a new cross-cooling system–lamp housing temp is reduced 25%; lens temp, 17%. A redesigned stirrup and improved tilt lock make using Chimera or similar light modifiers a breeze.

-New cross-cooling system reduces lamp housing and lens temperature
-Reduced weight
-Redesigned stirrup and improved tilt lock for ease of using light modifiers
