Although the advantage of using LED light bulbs is “Saving Energy”; its current market price and energy-saving effect still cannot compete with the compact fluorescent lamp’s. Yet, if the luminous efficiency of LED light bulbs can reach 80 lumens and its price can decrease by 40%, the cost of LED light bulb can catch up with that of the compact fluorescent lamp. In terms of the current production process of LED manufacturers, the demand of LED light bulbs will probably dramatically increase by 2010.

To analyze it by the approach of cost variancesIn order to investigate how much energy will be saved by using compact fluorescent lamps and LED light bulbs, “LEDinside” has conducted a survey on the prices and specifications of compact fluorescent lamps and LED light bulbs. Some incandescent lamps have also been used for in-depth comparison. The comparable standards include “luminous efficiency”, “ power cost”, “lamp cost”, and the “total cost”.

In order to reduce the greenhouse gas and cope with the problems rising from high oil prices and high energy consumption, many countries have announced new regulations in relation to using the high efficiency and cost saving light sources in replacement of incandescent lamps. Hopefully, attain the goal of saving energy and reducing the emission of CO2.
