    Power consumption is approximately proportional to V 1.6; Lifetime is approximately proportional to V −16; Color temperature is approximately proportional to V 0.42 [115] A 5% reduction in voltage will double the life of the bulb, but reduce its light output by about 16%.

    The dimmer switch used in conjunction with a dimmable CFL must be matched to its power consumption range; [58] many dimmers installed for use with incandescent bulbs do not function acceptably below 40 W, whereas CFL applications commonly draw power in the range 7–20 W. Dimmable CFLs have been marketed before suitable dimmers are available.

    lighter cathodes that can only handle a lower amount of power. They will function as a standard 40 W lamp on full-power ballasts, but may not last as long. These lamps are typically rated to last for 12,000 hours on a residential-grade ballast and only 6000 hours on a commercial-grade one. T12 1.5, 38 4 32 F40T12/ESP

    In December 2007, the federal government enacted the Energy Independence and Security Act of 2007 (EISA), which set maximum power consumption requirements for all general-service light bulbs producing 310–2600 lumens of light. Light bulbs outside of this range are exempt from the restrictions.

  7. Lumen (unit) - Wikipedia

    en.wikipedia.org/wiki/Lumen_(unit)

    It consumes about one sixth the electrical power of an incandescent light bulb producing the same light. Lamps used for lighting are commonly labelled with their light output in lumens; in many jurisdictions, this is required by law. A 23 W spiral compact fluorescent lamp emits about 1,400–1,600 lm.
