Lift high lamp for install lamps and lanterns of what?

First of all let's price, 20 meters high lamp, for example, 20 meters high lamp to configure for at least 12 lamps of 400 w light source to achieve a good lighting effect. Here I say some digression, said many friend's wrong understanding of the nature of lamps and lanterns, for example, power saving a lot of people said the LED lamps and lanterns, high pressure sodium lamp demanding, but it is not, or not depends on the power to save power, 400 w and 400 w LED the high-pressure sodium lamp is the same power, power consumption level, of course, also the same, take light, for example, want to take small power LED to replace the high power high pressure sodium lamp is almost a fable, because it simply can't satisfy the lighting condition of dozens of meters high.

then we continue to cut to the chase, a light 400 w high pressure sodium lamp, the price is in 850 yuan, the same one 400 wled ( Also in philips, for instance) Price is in 8500 yuan or so, this price gap can make you be clear at a glance, that's right, a difference of at least 10 times more, just think if high lamp are configured to big brand LED, not steel bar, the lamps and lanterns alone how many money? I think the price is generally difficult to withstand.

followed by photosynthetic efficiency, high pressure sodium lamp and metal halide lamp has a larger advantages, that is the penetration of fog is very strong, careful friends might have thought that car fog lamps used in the metal halide lamp and sodium lamp light source. Most high lamp installed in a large square or high-speed mouth corners, in the fog, good lighting can make traffic accident rate drops a lot. So high pressure sodium lamp and metal halide lamp is the two small advantages based on the lighting market, will not be replaced by LED products easily. 【 The above content released by jiangsu solar street lamps factory finishing 】
