The US Consumer Product Safety Commision announced a voluntary recall of Lighting Science Group lamps, warning customers to stop using the light sources. About 554,000 products have been recalled. The 120V LED lamps, sold as 6, 8 and 9W equivalents to 40 or 50W lamps, and were marketed under the brand names Sylvania (US), Definity, EcoSmart and Westinghouse.
Packaging is marked with model numbers A19, G25 and R20/PAR20.
Lighting Science Group is aware of 68 incidents of product failure, eight of which were accompanied by visible smoke or 'fire conditions'. The incidents include damage to sockets, melted fixtures, burned floors and damage to circuits and lamps.
All the products concerned were manufactured in China, and a small number were assembled in Florida or Mexico.
US federal law bars any person from selling products subject to a publicly-announced voluntary recall by a manufacturer or a mandatory recall ordered by the commission.
