Guangzhou Yansun Trading Company, Limited (Yansun) is a Walnut, California based company that manufactures lighting products. Yansun sold or offered for sale state-regulated light emitting diode lamps (SLEDs) in California, from March 2020 to March 2024.

This case was the result of an investigation performed by California Energy Commission (CEC) staff. CEC’s investigation and testing process identified that Yansun was manufacturing and offering for sale SLEDs that did not meet the efficiency standard, failed the marking requirement, and were not certified to the Modernized Appliance Efficiency Database System (MAEDbS).

To settle this matter, Yansun executed a Settlement Agreement with CEC on October 24, 2024, for $18,212.00. The penalty monies are deposited into the Appliance Efficiency Enforcement Subaccount established by SB 454 of 2011 (Pavley). Yansun has also agreed to a compliance plan to restrict sales of non-compliant products in California, and will add the appropriate marking, test, and certify all compliant models to MAEDbS before continuing to sell in California.
