Key Takeaways

• Traditional lighting controls are not equipped to take full advantage of LEDsg

• As the market continues to adopt LED technology it’s time to look into new technologies developed specifically for LEDs

• Today’s environment provides the Perfect Storm for intelligent• Today s environment provides the Perfect Storm for intelligent building systems and smarter lighting due to:– Rising costs of energy and new energy codes– Corporate “green” and LEED building initiatives– Need for facility professionals to do more with less

• Low voltage lighting systems provide all the control and more relative to traditional systems, but also provide building intelligence tools that create additional value for building ownersowners
