Big Lots stores announced a voluntary recall of its Classic Quarters Five Light Floor Lamps due to a potential shock hazard.

In a news release, the U.S. Consumer Product Safety Commission said the wiring for the lamps' light sockets can become exposed, posing a risk of electric shock to consumers. In addition, use of the recommended standard 40 watt lightbulbs can generate excessive heat, which can melt the double plastic shades over the bulbs.

The agency said it has received four reports of melting lamp shades, but no injuries have been reported.

The lamps stand about 5 feet tall and have a gunmetal or chrome-colored metal pole and five adjustable lights mounted on flexible metal tubes at the top. Dark plastic or multicolored double plastic shades cover each of the five lights.

Recalled lamps use standard incandescent or compact fluorescent lightbulbs and have labels marked with the model number “G-1843-5” affixed to the underside of the lamp base. The lamps can be further identified by SKU numbers 612007239, 612007829 or 612008982 at the beginning of the instructions. Lamps that use candelabra bulbs are not subject to this recall and can be identified by labels marked with the model number “G-1844-5B” and SKU numbers 612009036 or 612009037 in the instructions.

According to the CPSC, about 43,700 lamps were sold in the U.S. exclusively at Big Lots stores nationwide from April 2010 through November 2011, for $30 to $50.

The agency said consumers should immediately stop using the lamps and return them to a Big Lots store for a full refund.
