The large SiCOMPACT® R3 MAXI projector fulfils the highest demands for performance and visual comfort as well as energy efficiency and operating cost efficiency. As such the luminaire is perfect for lighting sports arenas and large public areas. Its innovative construction combines state-of-the-art lighting and luminaire technology to achieve light output ratios of up to 87%. The projector has been designed for luminous intensities of 2000 to 30000 cd/klm and can be adapted to a wide spectrum of optical lighting tasks with seven various adjustments. The lighting technology has been optimised for the use of high effciency 1000 W or 2000 W HIT-DE lamps and via the special reflector geometry allows precise control of light with minimal light spill and glare. For longer maintenance cycles and a very high luminaire service life, the projector is equipped with an efficient thermal management system, reflected in the construction of the luminaire: eye-catching cooling ribs dominate the rear of the slimline projector. The rear is secured by a robust and practical locking catch that can be opened without tools for maintenance. The luminaire form and front side determine the relatively large-area optic. Construction of the housing has been kept as flat and as efficient as possible in order to minimise the effects of wind. The special aerodynamics, low weight and sophisticated sealing system make applications possible world-wide in nearly all weather conditions.

• compact construction: reflector = housing
• flat construction: low windage area, low weight
• thermal management: reflector flush with diecast aluminium housing, integrated cooling elements in rear of housing, connection box with integral ignitor isolated from housing
• integrated pressure equalisation
• lamp cover of safety glass - no protective grid required
• 7 stepped distribution patterns from 2000 - 30000 cd/klm for a wide spectrum of applications
• luminaire light output ratio n_LB between 84% and 87%
• optics partly implemented with new hexagonal facetted technology
• V-shaped, inner shield prevents direct view of light source
• all-pole mains disconnection with opening of housing
• integral terminal and ignitor box - no external cables
