Designed the bottom up as a totally optimized LED street light system, the XSP Series delivers incredible efficiency of up to 100 lumens per watt and up to double the lumens per dollar of previous generations of LED street lights without sacrificing application performance. Beyond substantial energy savings and reduced maintenance, Cree achieved better optical control with our NanoOptic Precision Delivery Grid optic than a traditional cobra head luminaire. Better payback. Better performance. Better price. While other communities are still paying for costly re-lamping of their legacy systems, the Cree XSP Series will have returned your investment in lower operating expenses. The best alternative to traditional street lighting that pays for itself, then starts paying you.
