9. The light source or the unitary gasket-reflector according to claim 1 , wherein the unitary gasket-reflector has a distal end opposite the opening, the distal end having electromagnetic energy transmitting regions therein to permit the electromagnetic radiation from the light sources to enter the internal volume.

10. The light source or the unitary gasket-reflector according to claim 1 , wherein the unitary gasket-reflector has a distal end opposite the opening, the distal end having openings therein (or other electromagnetic energy transmitting regions therein) to permit the electromagnetic radiation from the light sources to enter the internal volume.

11. The light source or the unitary gasket-reflector according to claim 1 , wherein the channel is configured as a continuous channel forming a closed shape.

12. The light source or the unitary gasket-reflector according to claim 1 , wherein the unitary gasket-reflector comprises said channel and a second channel spaced from and opposite said channel to accept and hold a light modifier having an opening therein and having at least one outer edge and at least one inner edge, with said channel accepting and holding the at least one outer edge and the second channel accepting and holding the at least one inner edge.

13. The light source or the unitary gasket-reflector according to claim 12 , wherein the second channel has an associated second projection and wherein the second projection and the second channel are formed by at least first, second, and third walls of the unitary gasket-reflector, which first and second walls are spaced from each other and contact respective opposite sides of the light modifier, and which third wall connects the first and second walls and also provides a terminating wall of the channel that contacts an edge of the light modifier.

14. The light source or the unitary gasket-reflector according to claim 1 , wherein at least the portion of the light modifier inserted into the channel is substantially planar and has a substantially uniform thickness.
