LED corn light compare with Metal Halide light, which lamp have advantage?

Metal halide light widely use in warehouse , factory. It is necessary to use LED corn lights to replacement Metal lamp Famous lighting manufacturer GE lighting stopped to produce few model Metal Halide bulbs since 2015. EU indicates that metal halide must be phased out by 2015 and over 90%, since it has lower lumen output and less lifespan.
But LED corn light compare with Metal Halide light, which lamp have advantage?
Model
LED corn light 50Watt
Metal Halide 175Watt
Luminous Flux
6500lm
14000lm
Efficiency(lm/w)
130lm/W
80lm/W
CRI
80
52
Illumination at 5meter
126lx
105lx
Color Temperature(CCT)
2800-7000K
2800-7000K
Lifespan
>50000hrs
8000hrs

From the above table, we can know 50w LED corn light can replace 175W Metal halide light. In spite of luminous flux  of led corn light only 6500lm but efficiency higher than metal halide lamp .  
CRI
CRI can correct the color with original material need to use the light source of high color rendering index (Ra), its value is close to 100, the best color. CRI of led corn light is up to 80 Ra , suitable for color correct judgment.but metal halide light only 52 Ra , sometime make people got the wrong object's original color. Use led corn light instead of metal halide lamp , people don't have to worry about this situation.

Lifespan
Lifespan of Led corn light more than 50000 hrs, People do not frequent replacement lamp.although the price of led corn light more expensive than metal halide lamp , can save postage back. And reducing the trouble of replacement lamp.

LED corn light compare with Metal Halide light, LED corn light have more advantages. LED corn light is famous for green ,environment protection and energy-saving. Driven by dc power supply, no stroboscopic driven by dc power supply, no stroboscopic, for children, young people have the best eyesight protection.

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...
