Lamp manufacturers believe that price is a major barrier to more widespread use of CFLs (compact fluorescent lamps). Consequently, they have outsourced production from the United States to China and other developing countries. As a result, US workers lose jobs while US manufacturing capacity disappears. In addition, worker safety and environmental protection requirements are less stringent, and lamp quality and durability may be lower. Labor organizations point to manufacturer ‘double standards’ for lamps sold in the US and European markets. Most lamps sold in Europe are manufactured in Europe, where as many lamps sold in the United States are manufactured in China and other developing countries.
