Compact fluorescent light bulbs

Our best hope for the future is the sun, the ultimate renewable energy resource, continuously bombarding Earth with about 180,000 TW of radiant power. This is enough to power about 10 quadrillion compact fluorescent light bulbs over... 

The compact fluorescent light (CFL) is replacing the standard light-bulb we use in our homes and workplaces. Compared to a standard lightbulb, the CFL has a longer life and nses less electricity. Within about 20 days of use, the fluorescent bnlb saves enongh money in electricity costs to pay for its higher initial cost. 

A number of new technology promotion options are being explored in the lighting area. Work is undeiway on market transformation programs based on bulk procurement for improved efficacy incandescent light bulbs and for compact fluorescent lamps and fixtures. For incandescent lamps, adaptations of the infrared reflective lamp coating that is already in use on reflector bulbs are encouraged by the EPAct requirement. 

CFL (Compact Fluorescent Lamp) In lighting, CFL stands for compact fluorescent lamp, a type of light bulb that provides considerable energy savings over traditional incandescent light bulbs. 

Inorganic LEDs have advantages over incandescent lights They consume less energy, live longer, are more robust, have smaller size, and switch quickly they require better current and heat control than compact fluorescent bulbs. 

Fluorescent lamps are more efficient than incandescent lamps in converting electricity into light. In the near future, even more efficient LED (light-emitting diode) lamps will replace fluorescent lamps. Replacing a 75 W incandescent bulb with an 18 W compact fluorescent bulb saves 57 W. Over the 10 000-h lifetime of the fluorescent bulb, you will reduce CO2 emission by -600 kg and will put 10 kg less SO2 into the atmosphere (see Problem 19-22). Alas, fluorescent bulbs contain Hg and should be recycled at a collection center where Hg will be captured from the bulbs. They should not be discarded as ordinary waste.
