BLACK ARROW completes the series of Sagitter moving heads equipped with the innovative discharge sources by Osram. It features two machines enclosed in a single body, which both rely on a narrow arc discharge source with 280W integrated reflector, part of the now widespread HRI series. This source has an average life span of 2,000 hours and an extreme light efficiency that is well exploited by the innovative dual optical system used by this new projector. In this case the user can choose to use the projector in two distinct ways that share common features, resulting in visual effects never seen before. The shared features are: high-speed linear zoom with control definition, that modifies the beam width from 2° to 10° and the spot beam from 5° to 20°; independent effects wheel with circular 8-sided prism, linear 6-sided prism both with variable rotation and speed; independent low density frost effect designed for homogeneous light diffusion for coverage of small/medium surfaces; two stackable gobos wheels, of which one equipped with a dichroic gobos, indexed, rotating and customisable, which thanks to a precise electronic focus offer the user endless effect possibilities in the air and on backdrops. There are 13 dichroic filters fitted on the projectors mounted on a wheel that rotates at high speed in both directions. A large light blue LCD display offers the user a control software with a complete and intuitive interface, which can be browsed using a handy control wheel on the control panel.
