Frequently Asked Questions

Streetlights usually refer to a series of lighting device that is mounted on a column, pole or post and is separated along the road or highway,improving the safety of drivers and pedestrians. It is an important part of urban lighting. Traditional streetlighting generally adapts high press sodium or metal halide as lighting sources, matching with the reflectors and ballast. It is not very ideal in terms of energy-saving and contains toxic gases, which is very unfavorable to the protection of the environment. Today, when the concept of energy-saving and emission reduction is advocated.

 With the continuous development of LED technology and the continuous reduction of costs. More and more road projects are constantly using LED street lights to replace traditional street lights. From the appearance, some modular street lights look like modular led flood lights which also can be used as road light for area lighting, because their design and beam angle almost is the same.

For LED road lighting, generally 2800-3200K Warm white,4000-4500K daylight, 6000-6500K cold white options. What is difference for these color temperature?

♦ 2800-3200K Warm white. It looks like yellow lighting, similar to High press sodium bulbs. Compared with cool white light and natural light, warm light has stronger penetrating power. It means that in rainy and foggy places or weather, people can see a long distance to the LED street light with warm color light, which will improve the safety of drivers driving on rainy days. But the 3000K warm white is relatively low lumens.

♦ 4000-4500K Natural white. This is the color most like sunshine light. In real life, this color temperature of street light fixture is popular, it looks like a Metal halide lamp.

♦ 5500-6500K cold white. The color temperature of 5500-6500k will make people visually very cold and dazzling, which will lead to excessive visual fatigue, and under this color temperature condition, people’s ability to observe from a distance will also decrease, reducing the driving safety of drivers. But in these color temperature,6000-6500K led chips can be with much highest lumens output, saving much more energy, then it is the main reason why most of the customers purchase street led lights with 6000-6500K.

Conclusion: It is better to do led street lights with warm white 3000K or less than 2700k If it is installed in a rainy and foggy place. Or from experiences, it is ok to buy 6000-6500k types which is the highest lumens output.

Generally, the street light pole is 3meter 4meter 5meter 6meter 8meter 10meter 12meter 14meter optional. You should choose the different height of pole for your detailed projects. For some urban main roads, the street lights generally installed more than 8meter. But for some residential street lights, often only install less than 6meter height. What is more, you also decide how tall is street lights according to the wattage, such as led street lights 150W 200W, generally installed on the top of 8meter-12meter pole, but 50W 80W LED Street lights only are with 6meter street light pole.

In traditional street lights housing, the light sources are generally HPS or Metal halide lights, they are mostly with E27 or E40 base and glass cover. They all contain toxic gas inside, which is not good for the environment. Now more and more people choose the E27 E40 LED Corn street lights to replace these traditional light sources.

It should be decided by street light pole. Generally the distance between two street lights is 3-4 times of street light pole. For example, the distance of two street lights should be 36-48 meters if the street light pole is 12 meters. Of course, some people generally to expand the distance between two lights pole, to reducing projects budgets.

Yes. LED street lights can be with triac dimming, 0-10V dimming, or DALI dimming optional. Just use the relative dimming drivers for different dimming types.

Generally, most of the street lights are with high voltage, but for different countries or regions, the working voltage is different, such as in American markets, it is 110-120VAC 50/60Hz for street lights, but for European markets or Africa markets, 220-240VAC 50/60Hz is standard. What is more, for special applications, the street lights maybe only use DC12V DC24V DC48V low voltage.
