Apparatus for use with a light source including a ring reflector having an rim projecting outwardly from the light source for directing light from the source in a first direction, includes, a support, and a frame connected to the support and adapted to extend over the ring reflector to support a sheet of material in a position relative to the light source to redirect a substantial portion of the light from said first direction to a second direction. The support is coupled to the light source by a strap having two leg portions joined together by a bight portion, the two leg portions terminating at a first end coupled to the support so that the leg portions extend laterally on opposite sides of the ring reflector, each leg portion including a longitudinal slot for engaging said rim, the bight portion spacing the leg portions from each other by a distance less than a diameter of said rim, the leg portions being elastically displaceable to a distance greater than said diameter for engagement with the rim so that the apparatus is coupled in operative position relative to the light source.
