LED Troffer InstallationsNEW! LED Troffer Installations

This is a guide for contractors and specifiers who are replacing existing fluorescent troffers with new LED troffers or retrofit kits. Factors that should be taken into consideration include providing adequate illuminance, energy savings, occupant satisfaction, payback period, and using lighting controls. Development of this guide was sponsored by the Lighting Energy Alliance.


LED Lighting: An interactive video presentation

LED lighting can provide energy efficient, high quality lighting in many settings. The Lighting Research Center and NYSERDA present the following interactive video to assist contractors, building professionals, and other lighting installers with the often confusing process of selecting and installing solid-state lighting equipment for a particular application. Topics of the video include product selection, advantages and challenges of LED products, economic calculations, installation tips, and links to other available resources. Viewers can earn professional continuing education credits by watching the video and using the interactive features. Adobe Flash and a broadband internet connection are required.
