Cree, Inc. announced it has expanded its award-winning ZR Series LED troffer family by adding the new ZR-RK Retrofit Kit. Designed to deliver maximum improvement with minimum effort, the four-part design can be installed in only four minutes, upgrading outdated fluorescent lighting to premium Cree® LED performance in record time. For those lighting applications in which opening the ceiling plenum or removing old troffers is not an option, the ZR-RK Series provides unmatched ease of installation and an award-winning lighting experience quickly.

LEDtronics announces its latest series of UL-Listed LED Universal Retrofit Kits that is a true screw-in retrofit unit for installation into just about any existing lighting fixture. Other Retrofit Kits require the user to bolt/strap in a plate or heavily modify their existing fixture to accommodate the device—This next-generation Retrofit Kit does not!
