Stadium choose what is best, most reasonable

Stadium lights require very high brightness to large, illumination should be uniform, not light pollution and uneven illumination, can not appear blind, light intensity should be moderate, not too harsh, according to the rules of the game players stadium, and the lights next must fair. Select three rows of stadium lights general formula pole, or triangular light emitting pole, triangle dual emission pole, or side-emitting pole triangle. Three-row pole as shown below: 4 sets of pole mounted on the football field of the four corners, uniform illumination without blind spots. Philips 1000W high-quality electrical source, installation angle so that the light at the same time toward the football field in the middle bloom. The Triangle dual emission pole, is a triangular Medallions, only installed on both sides of the triangular Philips Electronics light, the other side without having to install, which is installed on both sides of the stadium directly opposite of the stadium from the lighting effects. Three luminous triangle pole, three sides installed electrical light, perhaps the other side of the aisle or the other volleyball court and so the need for lighting, the installation of the three light sources. Triangular side emitting pole, just as three rows of the same type pole principle, only one side can be directed towards the courts, the other side might be dead, perhaps the edge, perhaps the other people in the place, so do savings cost, reasonable investment.
