A snoot controls the shape of your light output. When placed in front of your light source it will result in a small circle of light. The size of the circle of light is determined by the snoot opening, its length, & the distance from your subject. Use this combination when there is a need to switch quickly between a standard reflector & the snoot. The built in grid keeps the light column tight with no spill. This is important when using this unit for hair light or high-lighting small still life objects. The honeycomb is now removable.
