UL is the most respected name in product safety in the United States. Using UL’s strict traceability guidelines, all components of a completed product meet or exceed UL’s quality and safety standards. When a lighting fixture is UL Listed, it means the final product has been tested and certified to UL standards. It then gets a holographic UL label on the backside of the canopy indicating it has passed. To see if an BRIGHTTIA fixture is UL Listed, look in description of the listing. Fixtures that are not UL Listed are constructed with UL Listed electrical components.
