There are also discussions to ban light bulbs of 50 watts and more. Switzerland banned the sale of all light bulbs of the Energy Efficiency Class F and G, which affects a few types of incandescent light bulbs. Most normal light bulbs are of Energy Efficiency Class E, and the Swiss regulation has exceptions for various kinds of special-purpose and decorative bulbs. In line with EU rules, Switzerland banned the import and manufacture of halogen
Phase-out of incandescent light bulbs to 40 percent more efficient than standard incandescent lamps designed for a 2000-hour life. Depending on size, voltage, and designed life, small low-voltage halogen lamps can have 70% higher efficacy than large line-voltage lamps. The high operating temperature of halogen bulbs may be a safety hazard in some applications. A compact fluorescent lamp (CFL) uses a fluorescent lamp tube which is curved or folded to fit into the space of an incandescent bulb and contains a compact electronic ballast in the base of the lamp. Compared to general-service incandescent lamps giving the same amount of visible light, CFLs use one-fifth
