A Tube Light 45 Degree Grid is a collapsible light control modifier that attaches to a 4' tube light to narrow its beam spread to a 45° angle. It is used to direct light precisely, eliminate unwanted spill, and help illuminate specific areas of a subject without changing the light's soft quality. The grid secures to the light using hook-and-loop straps and requires no tools for attachment. Two grids are included with this kit.
