| Using sophisticated computer modeling, PSE demonstrates the effects of planned lighting before construction through a combination of accurate light, color and spacing of 2000 custom fixtures in this two miles of mountain tunnel. The "before" comparisons are extremely accurate when compared to the final construction. Control of the lighting and staging of the lights is by touch screen PLC control, and special conductors and infrastructure suited to the harsh environments of combustion by-products and mountain conditions. |
