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
