1.What Is LED Street Light？
LED street lights refers to the lighting-emit diode lights which are used for streets. LED street lights are regularly installed on a street light pole, and are widely used for all kinds of roads, parking areas, sidewalks and other exterior areas.
LED street lights are very important for the city lighting systems, and are becoming more and more popular because they are energy saving, more efficient, long lasting and brighter.
2.What Are The Types Of The Street Lights?
Street lights have basically two types, tradition ones and LED ones.
Traditional street lights are using metal halide lights or sodium lights. This lighting system will include metal halide/sodium ballast, ignitor, capacitor and metal halide/sodium lamp.
LED street lights are composed of LED chips and LED drivers.
LED street lights have two types, one is SMD type and one is modular type.
SMW types are with die-casting and regularly with separated driver compartment.
And modular street lights are with led parts of modular, it is easier for replacement, maintenance and has better lumen output.
Besides the regular street lights, nowadays we also have solar street lights. Solar street lights are consisted of LED street lights, solar panel, battery and controller.
3.How To Choose Which LED Street Lights To Use?
As we have introduced above, there are several types of street lights, and if you have no idea which types of LED street lights to use, you can follow my below suggestions.

If you want street lights very bright and easy for maintenance, you can go with modular types. For SMD street lights, the highest lumen efficiency can achieve is around 150lm/w, while module street lights can achieve around 170lm/w. And module design is much easy for replacement and maintenance.
If you want LED street lights without using too much electricity, you can go with solar street lights. Solar LED street lights are wire-free and electricity, and it is very popular for the places where the electricity is expensive or the wire layout is inconvenient.

If the LED street light manufacture only provides 1 or 2 years warranty, it mean they are not confident with their products.
4.4What is the IP and IK rate for your LED street lights?
IK is to test how resistant LED street light is to impact. The standard IK rate for LED street lights should be IK10. This is important especially for typhoon areas.
IP is to test the water-proof and dust proof grade. All the LED street lights are used in outdoor, so the IP rate should be at least IP65 or IP66. For module street lights, it can achieve IP67.
4.5How many kinds of light distributions do your LED street lights have?

5.What Are The Main Areas To Manufacture LED Street Light In China?
The main areas to manufacture LED street light is southeast and south parts of China.
In the southeast areas, Jiangsu and Zhejiang province have many big and qualified LED street lights manufacturers. They are doing all die-casting, painting and assembly there. Many factories are make street lights ever since the traditional ones and have more than 20 years experience.
In south are, Guangdong and Fujian province have some LED street light manufacturers. This area is later than southeast areas for led street lights industry, but it is a very energetic areas, and make good products as well.
