Taken the green environmental protection does not contain harmful elements such as mercury and xenon, conducive to recycling and utilization, and won't produce electromagnetic interference (ordinary lamp contains such elements as mercury and lead, electronic ballast of energy-saving lamps will produce electromagnetic interference)

High efficiency and low heat: 90% of the electricity is converted into visible light (80% of the electricity generated by ordinary incandescents is converted into heat energy, and only 20% of the electricity is converted to light energy)

The market potential is low and low voltage, dc power supply, batteries, solar power supply, can be used in remote mountainous areas and field lighting, such as low power, low power.
