Wherever the highest standards of theatre lighting are required, ARRI Daylight and Tungsten lampheads are used world-wide. For the highest quality Daylight Fresnels the Compact Theatre range offers sizes from 2.5 to 6kW. These are supplemented by the Tungsten Fresnels of the Studio Theatre range from 1 to 5kW.

More specialised requirements can generally be met by lampheads from other ARRI Lighting ranges such as the discharge ARRISUN PARs and the ARRI X flat-field floodlights.

ARRI technology can also be combined with theatre technology from other manufacturers. Electronic ballasts can be adapted for use with discharge follow spots and we also offer a modification kit for fitting a discharge lamp to the ETC Source Four.

ARRI Theatre lampheads have been developed for the special requirements of Theatre, Opera, Musical and Festivals. Intelligent design features guarantee simple and effective operation even in difficult conditions. The wide range of lampheads and accessories even including the option of full motorization of all functions gives the designer the power

to achieve his creative ideal.
