Operating like a projector, the LTM Focal Spot focuses light through two glass plano-convex lenses to produce a concentrated beam of light with a smooth field and sharp edges. Four adjustable framing shutters cut and shape the light, creating slashes of light in almost any shape. Rotating 360°, this unit is used to highlight a specific area or add to a background. It attaches to the accessory holder on the front of the light by an optional retainer ring.
