LED bulbs often overrated


Independent research by the Dutch Metrology Institute has revealed that many LED bulbs do not meet the claims. After measuring the actual light output of the LED lamps, and their supposedly equivalent incandescent counterpart, it was found that the output of the LEDs was overrated up to 300%. Such exaggerated performance of LED light bulbs will lead to unsatisfied customers, and will eventually harm the reputation of solid-state lighting.
