In 1893, electric light technology was put on display at the world’s fair in Chicago. These lights were installed inside paper-mache buildings, and Chicago earned the nickname “White City.” A lesser known fact is that lighting caught many of the paper buildings on fire. These fires resulted in the creation of Underwriters Laboratories, or UL.
UL1598C certification provides building owners and managers a safety standard when considering LED Retrofit. Certified LED Retrofit products are labeled as UL “classified.” By using the word classified UL can distinguish field-installed LED Retrofit products from Fixtures, which bear the “listed” mark, and LED Lamps, which bear the “recognized” mark.
