Z0642DE Helios Fresnel Spotlights 20-67deg

Detailed Description

Helios Fresnel Spotlights have a fixed borosilicate fresnel lens and the lamp chassis is externally adjustable for beam angle selection.
Fresnel spotlights produce a soft-edged variable beam, particularly suitable for subtle three dimensional modeling and highlighting. The variable beam angle of 20°-67° allows a wide choice of throw and beam dimensions. Barndoors & colour filters are available as accessories, the latter being available in an enormous colour range & enjoying almost indefinite life in these luminaires, due to the low heat output from the discharge lamp.
