This is the 1000 Watt Molequartz One-Light Groundrow. The fixture, used in multiple units, is aptly named since it hugs the ground, presenting a low profile which is invaluable in lighting backgrounds or cycloramas. A mask is usually employed to hide the lights from view. The easily removed safety screen makes way for gel or diffusion filters.
The Groundrow uses lamps from 300-1000 watts in 120V, as well as 800 watt 240V lamps with a color temperature of 3200K.
Low-profile Cyc Light
At 6' (4.88 m) from lamp to cyc the Groundrow casts a beam 16' (4.88 m) in height which diminishes from 120 fc at the base to 45 fc at the top.
