Automatic lifting light, usually with a primary light source of high pressure sodium lamp or metal halide lamp, there are two reasons for choosing this type of lamps and lanterns, first of all, high pressure sodium lamp metal halide lamps and lanterns has the characteristic of high brightness, wide perspective. Second is the problem that high lamp manufacturer profits, market sales of high pressure sodium lamp is a lot of fake brand, genuine can obtain considerable profits.
in the lighting intensity and irradiation area actually LED lights can satisfy completely the requirements of high lamp lighting, it's not in high lamp is widely used on the main reason is the price.
by high pressure sodium lamp, the authenticity of 400 w full set price is in 500 yuan, and the good point of 45 wled lamp does not generally lower than the price of 200 yuan, under the contrast many people will subconsciously choose high pressure sodium lamp. Due to the lack of the understanding of LED lights, LED to a lot of people don't make a thorough comparison, two qualified 45 wled lamp illumination brightness is no worse than 400 w sodium lamp. Below we comparing two kinds of lamps and lanterns for a system.
first sodium lamp is composed of light source, ballast, capacitor, the trigger of four parts, that is to say, no matter what part of the problem will lead to lamps and lanterns is not work properly, even if the parts without problems, the service life of the light source is not more than 10000 hours.
and the LED lamp is different, it is the composition of the only two parts, namely the lamp bead and power supply, the damage probability is very low on the accessories, as we all know, the service life of the LED light source theory is 50000 hours, even if the short of it is not how much, the service life of LED lamp is longer than sodium lamp.
is power, then two 45 wled lamp brightness and two 400 w high pressure sodium lamp, but differ in power four times, we often see on the square of flash of light, it is more than 10 hours, the count down for a long time or LED lights.
actually LED lights in price is not as expensive as people imagine, in the long run it it was cheaper than other lamps and lanterns, because of its long life, low consumption, can be called a long-term investment. So configuration in high lamp light source suggest choose LED lights, because a lot of fake sodium metal halide lamp often appear problem, the LED light, lifting a very trouble, bad is both time-consuming and often, you should be careful when buying choice.
