With the acceleration of urban construction, more and more mountain are connected by the tunnel , we have been concerned about how to choose a good tunnel lighting, as the tunnel is semi-closed environment, we must choose the lamp which can properly light up the tunnel and come through the fog and have the features of the strong waterproof and rustproof ,the high-pressure sodium lamps is currently the most widely used, but with increasing demands on energy saving, plus that the light colour of the high pressure sodium and mercury lamp is narrow, the brightness is low, we begin to turn to LED tunnel lights, so, what is the difference between the LED tunnel lights and high pressure sodium in the end?

1, just from the luminous efficiency, the LED tunnel light is 90lm / w,the sodium light reach 120lm / w;

2, from the performance of through the fog, the golden yellow light of the sodium light can better through the fog, of course, which can also be replaced with warm white LED tunnel light;

3, in view of the initial investment cost, the price of the LED tunnel light is three to four times more than the sodium light;

4, as far as the saving the cost is concerned, taking into account the factors such as the power , LED lights can save more than 60 percent;

5, long life, LED tunnel lights can theoretically reach 50,000 hours or more, but limited by a variety of factors, such as lamps heat dissipation, the life of the power and so on, the life of the sodium lamp can reach 12,000 hours, considering the high cost of maintenance in the tunnel, the LED tunnel lighting is more appropriate;

Generally speaking, 100W LED lighting can completely replace 200W high pressure sodium (the specification of the sodium light is typically 250W), but we should choose the right products from the color temperature, light efficiency, heat dissipation, etc., in addition to a large number of products must be used for the project, we can make a relatively detailed investment plan to contrast,after the initial investment of the product, energy-saving performance and maintenance costs are analyzed. LED tunnel lights is better than the high sodium sodium light.
