Price of street light

In the price range of 20~50W, a product called Model N can be described as the “King of Cost Performance”. The reason for its low price is not that we produce “junk” products, but because its design structure is very simple, and it is also easy to install and maintain. However, in terms of elevation angle adjustment, the N model can only maintain a fixed angle, which means that users need to choose a suitable installation location. In addition, Model N requires an external drive power supply because it does not have a power supply compartment. Our customers usually place the power supply at the inspection port of the light pole.

ST18, which we affectionately call NOVA, is a star product in the price range of 50~150W. It is characterized by a glass lampshade, which can effectively prevent foreign matter such as leaves and bird droppings from accumulating on the back and keep it clean. The only regret is that the ST18’s elevation design is also fixed at an angle that cannot be adjusted.

ST19, which we call Falcon, shows excellent performance in the price range of 150~200W. It has a glass shade design with a smooth back that won’t collect foreign matter like leaves or bird droppings. It is worth mentioning that the ST19’s elevation angle can be adjusted horizontally and vertically, and the adjustable angle range reaches ±15°, providing users with more room for adjustment.

In the price range above 200W, ST17 Rifle series has become the best quality product. ST17 adopts glass lampshade design, the back is also smooth and will not accumulate foreign objects such as leaves and bird droppings. In terms of elevation angle adjustment, ST17 realizes the horizontal and vertical adjustable functions, and the adjustable angle range reaches ±15°, which ensures the highest level of light efficiency. On the whole, ST17 is undoubtedly the most attractive choice in the price range above 200W.

Efficiency of Street Light

Secondly, light efficiency is undoubtedly an important indicator. For LED lights, light efficiency is particularly critical, because higher light efficiency means that we can get more light when using limited power, which undoubtedly greatly saves energy consumption and achieves the effect of energy saving and emission reduction .

Nowadays, more and more countries are actively promoting the implementation of energy-saving and emission-reduction policies, which not only help to reduce energy consumption, but also help to protect our earth, make the air cleaner and the environment better.


In today’s social development, energy conservation and emission reduction has become an important national policy. On the basis of meeting the available requirements, every 1 watt of electricity consumption reduced means that we can save at least 0.01 kg of carbon dioxide emissions. This is of great significance to improving our environment and ecology. Therefore, we should actively promote the implementation of energy conservation and emission reduction policies, and work together to create a greener and more environmentally friendly future. And street lights with high light efficiency are more suitable for solar lighting systems.

By increasing the number and area of heat sinks, heat can be dissipated to the surrounding environment more effectively, reducing the working temperature of street lamps and prolonging the service life of lamps.

Improve the stability of the lamp: the heat sink can effectively absorb and disperse heat, reduce the accumulation of internal temperature of the lamp, thereby reducing the working pressure of the lamp in a high temperature environment, and improving the stability and reliability of the lamp.

Enhanced safety: The heat sink can quickly dissipate heat to the surrounding environment, reducing the temperature rise inside the lamp and reducing the risk of fire and other safety accidents. At the same time, the lower operating temperature also helps to reduce the heat radiation of the lamps to the surrounding environment and improve the safety of use.

Increase the life of the lamp: the design of the heat sink can effectively reduce the working temperature of the lamp, reduce the impact of thermal expansion and thermal stress on the internal components of the lamp, and prolong the service life of the lamp.

Energy saving and environmental protection: the design of the heat sink can improve the heat dissipation efficiency of the lamp, reduce energy waste, and improve energy utilization. By reducing the calorific value of lamps, energy consumption can be reduced to achieve the purpose of energy saving and emission reduction.

Optional accessories

The 3pin base has 3 contacts. When the light control switch is plugged in, it will automatically turn on the best LED street light at night when it is powered on, and turn off the light automatically during the day.

How can the 5pin base add 2 contacts on the surface of the 3pin socket. Typically used to connect to the dimming leads on LED drivers.

The 7pin base adds 4 extra contacts on the surface of the 3pin socket, mainly for DALI standard dimming control

For more detailed information about NEMA sockets, you can refer to another article on this website "What Is 3 Pin, 5 Pin & 7 Pin NEMA Socket And How to choose them?"

The street light control head is a controller for street lights, which can automatically control the switch of street lights according to the intensity of light.

Motion Sensor can turn on the lights when people come and turn off the lights when people leave, so as to achieve the purpose of energy saving.

Smart Controller is a terminal for remote control. To use it with a 5pin or 7pin base, it needs to be connected to the Internet through a gateway.

The Camera may need to be connected to the Internet, but it needs to be powered separately.

Knife switch, when the street lamp is overhauled, it will automatically cut off the circuit when the power supply compartment is opened to ensure the safety of personnel.

The function of ZHAGA Socket is close to that of NEMA Socket, and its volume is smaller and cheaper.

The role of other adapters is mainly to adapt to various installation environments, and we can also customize them separately if there are more needs.
