Bringing Intelligence to Outdoor Lighting - Which is Better Wired VS Wireless Solutions

568 views

Published on

As more and more organizations consider lighting upgrades for outdoor lighting, they are met with a unique opportunity to also bring intelligence to their lighting systems by bundling controls along with the LED upgrade. But controls are unknown territory for many decision makers. And with LED lifespans ranging upwards of 20 years, they want their construction or design professional to perform a comprehensive technology assessment before selecting a technology they will be using for the next generation. Today, both wired and wireless options are available in the marketplace, how does the professional make sure which technology is the best for the project? In this session, Rita Renner will explore the benefits of each technology as well as the challenges, then look at ideal applications for each. She will also examine actual case studies where only one control technology was used, as well as examples where both technologies were used together, to illustrate how real project teams made assessments and implemented the best technology platform for their situation.
