Cree has expanded its award-winning ZR Series LED troffer portfolio with the introduction of the new ZR FD LED Series, a commercial spec-grade troffer that delivers superior energy efficiency of 130 lumens per watt. This performance increase provides customers with up to 60 percent energy savings versus fluorescent troffers. The new ZR FD Series delivers 130 lumens per watt efficacy at 80-plus CRI. Its thin profile, lightweight design makes for easy installation in almost any plenum, reducing the need for layout re-design in retrofit applications. The product’s 3.9” height offers a quick and easy one-for-one replacement of inefficient fluorescent troffers in education, healthcare and commercial building applications.
