1. An LED luminaire comprising:
- a heatsink;
a support surface in thermal connectivity with said heatsink, said support surface having a plurality of light emitting diodes mounted thereto, said light emitting diodes electrically connected to a power source;
a plurality of reflectors mountable over said support surface, each of said reflectors positioned over one of said plurality of light emitting diodes and being a bi-focal reflector with a first reflector portion having a first curvature and a second reflector portion having a second curvature, said first curvature being a more gradual curvature than said second curvature, said first reflector portion having a first focal point and said second reflector portion having a second focal point, said first focal point being more proximal said support surface than said second focal point;
a plurality of optical lenses, each of said optical lenses positioned over one of said plurality of reflectors.
