1. Low power consumption and low operating cost: LED light sources with the same light efficiency can save more than 80% of energy than traditional light sources. For example, a 2000-meter bridge LED fence light only uses 10 kWh for one hour, and the annual electricity cost is lower than traditional light sources. The lamp saves tens of thousands or even hundreds of thousands of yuan.

2. Low protection cost: LED lamps operate stably and do not require high operating environment. They are not frequently replaced due to the influence of harsh weather environment.

3, long life: LED lamps and lanterns use solid semiconductor chips to convert electrical energy into light energy, plus epoxy resin packaging, can accept high-intensity mechanical shock and sensation. LED single tube life is 100,000 hours, light source life is more than 20,000 hours, calculated based on 12 hours of daily operation, its life is more than 5 years.

4. High luminous efficiency: The white light and halogen tungsten light effect is 12 ~ 24 lumens / watt, the fluorescent light is 50 ~ 120 lumens / watt, and its light source adopts black body radiation. Only about 10% of the emitted energy can be used in visible light. The rest is useless heat; in order to obtain one color, a color filter needs to be used to remove other colors, forming energy waste. The LED has an efficiency of 50 ~ 200 lumens / watt, a narrow spectrum, and good monochromaticity. Almost all the announced light can be used, and the color light can be announced directly without filtering.
