Abstract / Description of output

According to current energy efficiency labels, the majority of LED lamps on the market are considered as highly efficient devices. This makes it difficult to distinguish between lamps with different operational characteristics and performance. This paper introduces a comprehensive experimental-based labelling methodology for comparing LED lamp performance with reference to two additional important characteristics: light flicker and power factor. The new labelling methodology reveals that there is high diversity between different LED lamps with different circuit topologies but also for a given topology with different design choices. General consumers and design engineers can benefit from the simple and clear information presented by the set of comparative labels when comparing LED lamp performance.
