Why do LED lights have exaggerated wattage ratings?

[EthanLynn]

In China, exaggerated power ratings for LED lights have become an industry norm. Generally, the actual power is at least two-thirds of the labeled power, which is still acceptable—just buy a higher wattage. LEDs are energy-efficient and low-cost: LEDs have high luminous efficiency, nearly twice that of fluorescent lamps. For the same daytime running lights, the energy consumption of LED components is only 1/20 that of halogen lamps. The cost of LED components has also decreased significantly year by year, and currently, costs and prices continue to drop by more than 20% annually. LEDs have excellent durability: LED components have a simple structure, excellent impact and shock resistance, are not easily broken, and can adapt well to various environments.
