True or False: Quality electrical equipment should have the Underwriter's Laboratories (UL) listing mark.

The statement is true because having the Underwriter's Laboratories (UL) listing mark indicates that the electrical equipment has been tested and meets specific safety standards. The UL mark provides assurance to consumers and professionals that the product has undergone rigorous testing for safety and performance. This includes checking for potential hazards, such as electrical shocks or fire risks, and ensuring that the equipment complies with the necessary regulations.

The UL listing is particularly important in horticulture practices, where reliable and safe electrical equipment is essential for maintaining proper environmental conditions and supporting growth. Therefore, choosing equipment with the UL mark is a critical factor in ensuring both safety and efficiency in horticultural settings.
