www.illuminatedcomponents.com www.illuminatedcomponents.com | PHONE: 561-241-8600 What is Driving the Lighting Market to LED and SSL? Why are LED’s being used in new lighting applications? Rising cost of energy Falling cost of technology LED cost per lumen decreased by 30% over the past year Government regulations RoHs (reduction in mercury content impact CFL devices) Emissions reduction targets Building performance requirements Increase in use of lighting controls Energy efficiency requirements
