A light bulb package marked “UL Compliant” is no assurance that the LED T8 has been tested or approved by the Underwriters Laboratory. It only means that the manufacturer has followed recommended UL guidelines in production and technical aspects. A “UL Listed” LED bulb has passed stringent tests put forth by UL, and consumers are advised to look for the UL Listed mark.

In the race to garner a share of the emerging LED market, manufacturers may use the UL Compliant mark to help sell more light bulbs, but this is no guarantee of bulb quality. Consumers should be wary of new LED bulbs and LED panel light which are priced very low, are sourced from unknown suppliers, or have unrealistic product claims.
