Abstract: Improvements a portable elevated lighting system that uses LED lighting elements for illumination. The LED lights are selected based upon the light transmission angle so the fewest number of lighting elements are needed to provide an even flood or focus of light from the system. A reflector works as a heat sink to remove heat from the LED lights and extend the operation life of the LED's. Thermal paste and or a thermal pad is used between the LED lighting element and the frame to conduct sufficient heat away from the LED element. Two versions are shown as a stadium light and as a circular flood light that provides lighting without shadows or bright areas. The system can be operated from a generator or solar for charging batteries so the lighting can operate self-contained without producing noise.
