Recommendations
Years to Break Even 47 Years to Break Even with Induction Lighting
Induction Lighting is the best option for Portland State Better Health, Safety & Environment No flicker and less glare provides maximum eyesight protection Crisp White Light, choice of color temperatures - Increases safety & performance Outstanding Color Performance - no shift over lamp life Less CO2 output and mercury waste to dispose Longer Life 100,000 hrs
Total CO2 Savings By adding Induction Lighting to all existing garages we will decrease the amount of CO2 that is emitted annually by 25 metric tons
Grants and other Programs Energy Trust $100,000
