What is THD? What causes THD? What do customers often say that THD<15% in LED LIGHT refers to?
THD stands for total harmonic distortion, which is a measurement of the distortion of an electrical system caused by the original frequency harmonics. THD is usually expressed as a percentage, and a lower percentage means less distortion.
THD can be caused by nonlinear loads in electrical systems, such as electronic devices and LED lights. These devices can introduce harmonics into the system, resulting in an increase in THD.
Customers often praise LED lamps with THD levels below 15% for their high efficiency and low distortion. These lights are known for providing clean, stable lighting without causing interference to the electrical system.
Rokee's luminaires comply with EN IEC 61000-3-2:2019 and have obtained EMC certificates and test reports issued by authorised lab with ISO17025 qualification, ensuring that the harmonic currents generated by our luminaires do not distort the voltage waveforms in the public supply network.
