LED light bulbs will eventually be what we use to replace incandescent bulbs – CFL are a temporary solution to energy-efficient lighting. The reason LED shave not yet displaced CFL from the market are twofold: the first generation LED bulbs had a narrow and focused light beam, and the cost of the LED bulbs was too high.
Recent developments in LED technology, however, have been addressing these issues. LED have been’clustered’ to provide more light, and mounted within difuser lenses which spread the light across a wider area. And advancements in manufacturing technology have driven the prices down to a level where LED bulbs are more cost-effective than CFL or incandescent bulbs.
