Underwriters Laboratories Inc., an independent product testing facility based in Chicago, said consumers should beware of a type of fluorescent lamp bearing a counterfeit UL stamp of approval for Canada and the United States.

Underwriters said the lamp — identified as ‘8W A19 110-130 V CL 50/60 Hz dimmable SH O12807’ — has never been tested by the Laboratory and is not eligible to exhibit the mark.

Underwriters said Blanchard Distributing and possibly other retailers sell the product.

The laboratory is advising purchasers to return the product to the store where they bought the lamp for a refund
