What Does Energy Star Qualified Mean On A LED (Solid State Lighting) Fixture?
Energy Star qualification of consumer products continues to grow. The Energy Star logo is one of the most recognizable symbols of quality and performance in modern American culture. Because Energy Star qualification of Solid State lighting (LED) is relatively new, it is important to define what exactly qualifies a luminaire to carry the label. Following are a few of the key features and measurements that are required for qualification. General Requirements Correlated Color Temperature – (CCT) must fall within eight established color temperature quadrangles (Nominally 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, 5700K or 6500K) and deliver specific temperature tolerances established for each of the individual numbers. (i.e. 2700K nominal must be 2725 ±145K, so it can range from 2580 to 2870K; 3000K nominal must be 3045 ±175K, or a range from 2870 to 3220K.) In addition to the tolerance, maximum temperature variances over its lifespan and viewing angle are defined. Color Rendering Index – (
