With the global incandescent disabled regulations have been implemented, the existing incandescent will be replaced with energy-saving lamp CFL or LED bulbs. Due to the current high cost of LED chips and also heat problem has not been fully resolved, so CFL energy-saving lamps in the next five years, there is still much room for market growth, but with the LED chip to reduce manufacturing costs and CFL energy-saving lamps environmental pollution problems still exist, so five years after the LED bulbs will gradually become the mainstream market demand.
