Intertek has expanded its Class P program to include LED light engines, allowing luminaire manufacturers faster, simpler product certification at reduced costs. Typically, luminaire manufacturers’ only option for LED light engines are standard Recognized devices that require additional evaluation by a Nationally Recognized Testing Laboratory (NRTL) for changes made by the manufacturer. In many cases, this results in the need to perform additional testing, delaying time to market and increasing costs. With the expansion of Intertek’s Class P program, manufacturers can now source and incorporate different LED light engines of the same Class P Listed rating into lighting products without retesting each time a new light engine is used.
