One of the best ways to get maximum lumens with less power and cost is to create a LED mirage. In this pole, blades are rotated in a vacuum to achieve high speed. Since mass density of the vacuum is about 6.5*10-27 kg/M3, while density of air is 1.225 kg/m3, the blades rotate in the vacuum faster than in air. When LEDs are mounted on the blades a continuous and non-flickering supply of light is created.
