Different specifications LED street light price list

In the early years, customers didn't know about LED street lights and bought cheaper LED street lights. When installing street lights, the street lights picked up accidentally fell on the ground, and the "street lights" instantly became broken... See how the current LED street lights are:
1 module street light VS conventional street light price: 2000~3000
Module street light
Module street light: In the early years, the integrated street lamp was difficult to develop the mold due to technical limitations, and then the module street lamp was developed, and the light source was inlaid one by one, thus solving the technical problem. The disadvantage is light interference, long-term photoaging.
Conventional street lights: This kind of street light is the most common on the market, the price of high LED street lights. Most of its chips, power supplies, etc. use brands (individual merchants), but its street lamp housing has no heat dissipation design, which may cause other problems.
2 integrated street light VS module street light price: 300~2200
Integrated street light
These street lamps were developed in the early years of conventional street lamps and early modular street lamps. The manufacturers further developed products according to the market. These products further reduce the price while ensuring the quality. The high-power street lamps have higher prices and lower power prices.
Integrated streetlights: Manufacturers have begun to develop integrated streetlights. Now the technology can completely proof and eliminate the products. There is no technical limitation in the early years. The advantage of integrated streetlights is that the light distribution is good, and the lamp housing is integrated heat dissipation.
Module street light: It is also the manufacturer's consideration of the market to ensure the quality while reducing the price. Perhaps there is no high-profile module street lamp configuration, but it also uses the brand's chip and power supply components, and the lamp housing has a heat dissipation design on the back.
3 low price street light
Low-priced LED street lights are generally based on customer demand, reducing quality to achieve low prices.
The higher the price of LED street lights is not necessarily the best street light, but the low quality of LED street lights has never been heard...

Li-ion Battery With SMBUS refers to the battery datas can be collect through equipments based on SMBUS data communication, it usually applied to the military grade battery which need higher safety level protection .but as these battery have SMBUS inside ,it also should meet these requirements as :

1.The rated voltage is high (the operating voltage of the unit is 3.7v or 3.2v), which is about equal to the series voltage of three nickel-cadmium or nickel-hydrogen charging batteries, so as to form the battery power supply group

2.The self-discharge rate is very low, which is one of the most prominent advantages of the battery. At present, it can reach less than 1% per month, less than 1/20 of the nickel hydrogen battery.
