| 1. A theatre lighting apparatus comprising:
a base,
a communications port,
a processor,
a memory, and
a lamp housing;
the lamp housing comprising
a lamp,
a reflector,
a first color varying system,
a second color varying system,
an output lens,
and a shutter;
wherein the lamp housing is remotely positioned in relation to the base by a motor;
wherein the first color varying system is comprised of cyan, magenta and yellow color filters;
wherein the lamp, the reflector, the first color varying system, and the output lens cooperate to project a first variable
colored light;
wherein the second color varying system is comprised of a first plurality of red light emitting diodes, a first plurality
of green light emitting diodes and a first plurality of blue light emitting diodes;
wherein the second color varying system cooperates to project a second variable colored light;
wherein the first plurality of red light emitting diodes, the first plurality of green light emitting diodes and the first
plurality of blue light emitting diodes are arranged about the circumference of the output lens;
wherein a first command received by the communications port varies the first variable colored light into a first color;
wherein a second command received by the communications port varies the second variable colored light into a second color;
wherein a third command received by the communications port causes a strobing effect of the first variable colored light;
and
wherein a fourth command received by the communications port causes a dark phase of the second variable colored light.
