Are CFL equivalents available for all incandescent lamps?
Not yet. The highest wattage CFLs currently available as replacements for incandescent lamps are rated at approx 20 watts, equivalent in output to a 100 watt incandescent lamp. However, using CFLs as replacements for incandescent or tungsten halogen lamps can create problems. as follows: Physical size – CFLs may be physically bigger than the original lamp, and may not fit into existing lighting fittings The lamp cap options with CFLs are limited CFLs cannot be used in fittings with built-in presence detectors The colour of the CFL can appear cold. CFLs have a perceptible warm-up period, making them unsuitable for rooms used for short periods. A pinhead-sized amount of Mercury is used in the manufacture of CFLs, requiring their careful disposal, so while they may be more energy-efficient during their lives, their manufacture has a poorer environmental footprint than incandescent lamps.
