Like all members of the M-Series, the M40 unifies the advantages of a PAR light and a Fresnel fixture. Due to the unique lens-less MAX Technology, the unit is open face and thus very bright, but also focussable over a range of 18 to 52° HPA (Half Peak Angle), casting a crisp shadow. The reflector characteristics is optimised for 4000 W lamps, but can also be used with 2500 W lamps.

The lamphead is equipped with a CCL module (compensation for cable loss). When operated with the ARRI EB 2.5/4 with CCL, full power is maintained all the way to the lamp even when very long cables are used. This means uniformly high light output independent from cable length.

Lens-less MAX Technology: Easy to use
Around 30% brighter than AS 40
Same size as AS 40 but over 3 kg lighter
Compensation for Cable Loss (CCL)
Tubular steel yoke
Two disk brakes with steel handle
Cross Cooling allows safe operation at extreme tilt angles
Protection class IP 23

Our Newly Acquired ARRI 2.5/4KW High Speed Electronic Ballast with ALF is designed for use with ARRI 2500W or 4000W HMI luminaries for high-speed photography at 500 to 5000 frames per second. The ballast operates 1000 Hz rather than the typical 50 to 200 Hz and incorporates ALF (Active Line Filter). 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 infrastructure.

Flicker-free light up to 5000 fps
When combined with an adequate HMI lamp, at least 5 times more light output than a tungsten light of the same power
Light intensity increased by at least 5%
Constant lamp power
Constant color temperature
Constant light quality
Control of electric power of the lamp between 50 and 100%
Variation in power supply voltage of 10% has no influence on the power of the lamp
The ballast is built into a casing with IP21 or IP22 protection
