200W LED high bay light replace 400W Metal halide light ,why?

Metal halide lamp is widely used in industrial buildings, streets, square , however, More and more people like to use LED high bay light that these places In recent years. Compare with Metal halide lamp,what is the advantages of LED high bay light? Why people like LED high bay light?

LED high bay light is known as the fourth generation of energy saving lighting products, what is the advantages of LED high bay light? environmental protection, no mercury, no ultraviolet ray;Energy saving: high light efficiency, current production reached 120 lm/w;Long life: 70% optic retention lifetime of 50000 hours.Not afraid of vibration, can realize the dimming, and intelligent control.Metal halide lamp belongs to the high gas discharge lamp, luminous body area is small, light is gathered, irradiation distance, strong penetrating power, but the light color is a bit poor, slow start, high uv content, cannot use at close range, feel to the naked eye flash frequency.

Metal halide lamp by using inductance ballasts, its power consumption is high, high working current, start instantly produce very high starting current, 400 w metal halide at startup current moment as much as 15 years or so, the electrical life influence is very large, often damage the facilities of air switch.And ballast itself consumes a lot of energy, give users a huge bills, speeds up the circuit aging time;LED high bay light by using constant current drive, low power consumption, high power factor, to avoid the above problems.

High color rendering index, in the light to see clearly, colour is true;On the other hand, in the light to see not clear, light is fuzzy, the object distortion.Metal halide lamp only 65, color rendering index is low.Working in these light easy to cause myopia and visual fatigue. Color rendering index of LED high bay light is up 80, Can give workers a comfortable environment with its eyes.

Ultraviolet light is a terrible light that can cause a person's eyes and skin suffered serious damage, cause eye and skin cancer.Traditional light source uv content is very high, such as metal halide lamp uv content accounted for 34% of the total luminous flux, long-term close under the metal halide lamp work caused considerable damage to human body, LED high bay light don’t contain UV.

What ways can see LED street lights to replace the high pressure sodium lamp?

Image
Under the condition of current technology,luminous efficiency of  LED street lamp  is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort. Followed by "irradiation uniformity", although the  LED street lamp  lighting is relatively concentrated, but can be by the light path of the second design, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so a...

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light c...

Safe travel: TEK LED high bay light illuminate the locomotive base

Image
In recent years, China's rail transportation has been developing rapidly, and many second and third-tier cities have made great efforts to build urban subway projects, which have brought convenience to people.Subway passenger traffic is large, the operation security is always the top priority, the metro management department attaches great importance to the security of the train, and TEK LED high bay light  illuminate the locomotive base, which facilitates the maintenance and maintenance of subway vehicles. Traditional lighting there exists large droop, short service life, the problem such as glare, can't use how long will be replaced, is not only the economy, and the human eye in this light, easy to produce fatigue, especially the night repair subway locomotive, a bit not careful see not clear parts fault, cause hidden trouble.Today, many subway lines use LED high bay lights , which make lighting more efficient and more efficient.Second, can improve work efficiency, the ligh...
