The Limelight VB-1180 Compact Lighting Boom has a unique parallelogram design that makes it one of the most flexible support tools on the market. One of the more annoying and potentially hazardous aspects of overhead lighting involves the need to adjust the angle of your light source whenever you adjust the height of the boom. The VB-1180 cleverly addresses this problem by using a levering arm to self-adjust the light source's angle to keep it constant during changes in height. Subsequent angle changes are made simple using the handle at the pivot point that allows you 360 degree control of the head extension.
