Q:How many watts are the street lights?
Small common 60 watt city street mercury lamp, sodium lamp 110 and 220.
Q:How to identify LED street lamps do well or not?
Overall, 1 lumens per watt lamp (what is the value of the lamp lumens not) are now generally more than 85LM.2, the light distribution curve of the lamp is how, now popular is bat wing light effect.
Q:What's the reason why the LED street lights don't work?
Fault phenomenon 1, all LED does not light 1), if the reason is: city power protection switch trip, hit it, and if the power is not bright, generally LED drive power failure,
Q:What's the reason for the flash of LED street lights?
Should be the power line station, power supply to a startup, behind the low voltage, so the lights flashing.
Q:What ballast does the street lamp use?
You should first look at what is the light source, there are high pressure sodium lamp, low voltage lamp, high-pressure mercury lamp, metal halide lamp, ceramic metal halide lamp, LED lamp and energy-saving lamp, fluorescent lamp, electrodeless lamp and so on, to see what, some others do not need to ballast, general use now most of the high intensity discharge lamp, it is need to use high pressure sodium lamp, ballast or electronic ballast
Q:Is it possible to use 100W LED power for street lamp power supply?
Cost problem, a 100W street light, generally more than 3000
Q:Which is better, the LED street lamp and the traditional street lamp?
For street lighting and tunnel lighting projects, the sodium lamp itself has a large power, greater starting current, and thicker cables. Led because the power is small, the cable needs small, the overall cost of the project, consider the cable, then can be about 20% cheaper. The power can be saved by about 30%, and the service life is increased by 50%.

Q:Energy saving control of street lamps can save energy?
Single lamp installed variable power ballast: this measure is to install a power ballast can transform in each high pressure sodium lamp, with the same, at 12 o'clock in the morning, on the road almost no vehicles and pedestrians in the low traffic roads still maintain a high intensity apparently is not necessary. But some roads are not suitable for the implementation of the night lights lit, then can use the variable power ballast, low in road traffic flow, appropriate to reduce the power of the bulb, the bulb 50% to 60% at rated power, when the lamp power while reducing from 40% to 50%, but the road illumination only reduced 30%. Can guarantee the road traffic safety requirements. But even in the midnight voltage increases when the overload phenomenon does not appear light bulb and ballast, which not only can save a lot of power, but also can prolong the service life of the bulb and ballast lamp, which saves a lot of maintenance costs.
