Filmgear 1.8/1.2kW Daylight HMI Power Beam Lamphead

ARRI’s High Speed ballasts accept the challenge of modern digital high-speed photography with ease.

Running lamp frequencies up to 1,200 Hz High Speed ballasts facilitate high quality flicker free images even at frame rates of 1,000 fps and in many cases beyond even with a single discharge daylight source. Set to High Speed mode, ARRI electronic ballasts supply the lamp with a greatly raised square wave current, allowing worriless shootings for many various application such as SFX, VFX, commercials, sports, industrial applications, automotive component testing, ballistics or material testing.

ARRI High Speed electronic ballasts are available up to 800 W.

Weighing only 125 lbs and having a small shallow profile of merely 23”, the Alpha 18K can use a Ceramic glass lens or Standard 24” Fresnel to create the smallest, lightest and most versatile 18K ever designed.

At the core of this innovation is a custom made reflector molded out of quartz composite material. This allows the lamp to be placed much closer to the reflector, therefore reducing the physical size of the Alpha 18K by a third compared traditional 18K’s on the market. The light output from this new reflector increases output by nearly 15%, adding a softer and smoother lighting pattern compared to the oversized conventional aluminum reflector.

The extrusion/vent system is precisely angled to get maximum cooling efficiency , the small diameter reflector allows for better heat circulation, along with a new back bulkhead, which assures that the Alpha 18K operating temperatures remain within specifications in any critical position, including straight down.

A double suspension system (one to the lamp heat sinks and one to the chassis support) makes the Alpha 18K lamp less fragile to rough handling, occurring during location transportation.

Whether it’s creating a soft Fresnel look or a hard shadow using the open eye set-up, the Alpha 18K gives any cinematographer or lighting director the tool he needs to get the job done.
