ST2/3

ARRI TRUE BLUE represent an unprecedented evolution of the studio fixtures that have been popular workhorses for over two decades. Following extensive research and feedback from lighting professionals around the world, combined with advances in technology, ARRI has designed a series of six highly innovative lampheads with over 30 new improvements for studio and location lighting. ARRI Fresnels are available in both manual and pole-operated versions.

Using a 3000 W lamp allows a 65% higher light output while maintaining the size and weight of the fixture. Modern studio dimmer systems have the capacity to support 3000 W, and in contrast to 5000 W lamps, this power class can be operated within the standard 16 V - 230 V power grid of most countries. This saves costs in cabling and energy, and purchase costs of the fixture itself. Another possible scenario is a switch to HD recording systems, which are still less sensitive than SD cameras. In these situations the 2000 W lamps can simply be replaced with 3000 W lamps to provide the illumination headroom required.

Note: This change does not apply to the 120 V version!
