Arnold & Richter Cine Technik is hard to beat when it comes to film cameras and lights. The company is the global market leader in its field and has nearly a century of experience. The ARRI L-Series of LED lights is particularly versatile. They cast both large television studios and small interview setups in just the right light, while lighting the stage for live appearances in both huge event venues and small theaters. Large-area Fresnel lenses five, seven or ten inches (approx. 13, 18 and 27 centimeters) in diameter, depending on the model, provide for optimal light distribution from the ARRI LED lampheads. These lenses are made of the high-performance plastic Makrolon® from Covestro, formerly Bayer MaterialScience.

“The choice of material and the optical design enable a very even illumination of the set, which is not a given with multi-colored LED systems,” says Markus Zeiler, General Manager of the Lighting Business Unit at ARRI. The polycarbonate material can be shaped as desired to precisely bundle and direct the LED light.

Lower energy consumption, higher light output
According to Zeiler, “LED lampheads require only around one-fifth the energy of comparable tungsten lamps, which also generate significantly more heat. Our customers thus get higher light output while at the same time saving energy.” This is due in part to the high transparency of the lenses, which is also retained as the material becomes thicker. The majority of the light can therefore be used for illumination.

Another advantage of the Makrolon® lenses is the precise color rendition. This is particularly important for the L-Series C (Color) lights, whose color can be steplessly adjusted over a wide range. “It can display the entire rainbow spectrum of our new corporate logo,” says Dr. Klaus Reinartz, Covestro Marketing Manager for LED Lighting in the Europe, Middle East, Africa and Latin America region.

Operation of the new luminaire is similar to that of conventional Fresnel lampheads, so lighting technicians and lighting designers will not have to adjust how they work. Nor do they have to be overly cautious amid the hectic routine on the film set. Thanks to the good fracture resistance and temperature stability of Makrolon®, the lenses can withstand quite a bit of rough handling.
