Regent 500-watt halogen bulbs
Check against the official notice below — it lists the full affected range.
Cooper Lighting and the Consumer Product Safety Commission are warning about Regent 500-watt halogen bulbs (model numbers WM500Q and BP500Q) that can generate extremely high temperatures and pose a fire hazard if they come into contact with flammable materials like curtains or clothing. These bulbs are designed for outdoor work lights and flood lamps, but some consumers may be using them in indoor fixtures like torchiere floor lamps, where they should not be used according to safety standards.
If you currently have a 500-watt halogen bulb in a torchiere or other indoor residential fixture, you should remove it immediately. The bulbs are safe to use only in outdoor work lights, flood lamps, and similar outdoor fixtures. Cooper Lighting is asking retailers to add warning labels to bulb packages currently in stores, and new bulbs will include the label stating "Warning: Fire Hazard! Do Not Use In Torchieres Or Other Indoor Residential Fixtures."

These 500-watt light bulbs generate very high temperatures, compared to incandescent and lower wattage halogen bulbs and can start a fire, if they come in contact with curtains, clothes or other flammable material. These bulbs are intended for use in outdoor work lights and flood lamps. To meet the current Underwriters Laboratories standard, halogen torchiere floor lamps must be equipped with a protective glass or wire guard and have a halogen bulb that is 300 watts or less.
Cooper has asked retailers to add the label to bulb packaging currently on store shelves and new 500-watt halogen bulbs will contain the label. Consumers currently using these 500-watt bulbs in a torchiere or indoor residential fixture should remove them immediately. Consumers can continue to use the 500-watt halogen bulbs in work lights, flood lamps, and similar outdoor fixtures.
Current packaging for the Regent 500-Watt Halogen Bulb, with model numbers WM500Q and BP500Q, does not contain the recommended warning label of the American National Standards Institute (ANSI). The label should read, "Warning: Fire Hazard! Do Not Use In Torchieres Or Other Indoor Residential Fixtures." Cooper has asked retailers to add the label to bulb packaging currently on store shelves and new 500-watt halogen bulbs will contain the label.
