PC (Pebble Convex) Flood Fresnel PC (Pebble Convex) Profile spotlight The flood consists of a reflector in a box, with no lense. The reflector concentrates the light to the opening of the box. You can only control the general direction of the flood. (Pronounced "Frennel) The size of the beam is adjusted by moving the reflector and lamp farther or closer to the (Fresnel) lens. The beam is shaped by the four "barndoors" attached to the front of the lantern. The PC works in basically the same way as the Fresnel. Instead of the Fresnel lens this lantern uses a modified plano-convex lens with a pebbled effect on the plano (flat) side. When the two lenses inside the spotlight are far apart the beam of light is narrow. With the lenses close together the beam is wider. The profile gets its name from being able to project the shape of anything, formed by either the shutters or a "gobo" (thin metal with a shape cut out of it).
