Why some track light have UL certification? But other track lights have not? What is the difference between the two?
The UL certificate is issued by the Underwrites Laboratories and is one of the most authoritative certifications in the world. The track lights obtained from this certificate are safe and reliable so it can be freely circulated throughout the United States. Due to the high price of the certification, the track lights have the UL certificate are usually more expensive. In order to balance the other countries with low purchasing power in the world, we have set up track lights without UL certificate, and the price is usually much cheaper.
