Part of Arri's True Blue series, 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.

This is an Arri 50' Head to Ballast Cable that connects the Arri Compact HMI 2.5K, 4K, Arrisun & Arri-X 40/25 HMI lights to their ballasts.

This is an ARRI 4-Leaf Barndoor Set for the ST5 5000W Studio Fresnel. Barndoors attach to the front of a light and are used to restrict light from areas of a set. ARRI barndoors are heat resistant and rotatable.

This 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.

Arri Filter Frames are circular and heat resistant. Filters can be cut and sandwiched into them, and they slide into lamphead accessory holders. Sizes are a little bit larger than the fresnels.
