If you're looking for the ultimate in beam control, look no further than the Optical Spot by Lindsay Adler for Bowens from Westcott. The package includes a focusable 150mm f/3.5, Canon EF Mount lens in a snugly fitting housing that virtually eliminates spill light, directing it all forward through the eight included gobos or five color gels allowing you to project patterns on any subject or surface or creatively color them. Even greater beam control is provided by the four cropping blades that are built into the housing. Purchase of the Optical Spot also gives you access an exclusive 40-minute video with Lindsay's Top 5 Uses to spark your creativity. The Optical Spot is compatible with strobes up to 600Ws (with the modeling light off) or COB LEDs up to 100W.
