Currently with lighting being the major aspect for Christmas decoration manufacturers, now there are manufacturers especially of two of the most popular lighting products, the fiber optic trees and full sized pre-lit trees who have opted not to go for UL testing.
This organization UL which regulates use of electrical products even for Christmas decoration manufacturers was founded by electrical inspector William Henry Merrill after several fires which originated in Chicago, in 1893. This company soon transformed itself into a busy testing laboratory first testing Christmas tree lights for Christmas decoration manufacturers in the year 1905.
Today UL is an international organization with subsidiaries or associated companies around the world testing a wide variety of electrical products including those for Christmas decoration manufacturers and building material. |
