How to prove 500W LED stadium light can replace 1500W metal halide lamp？

Now many construction sites also stay in the use of 1500W metal halide lamp（MH） as a nighttime construction lighting, instead of using LED stadium light. A part of in order to save money, and part of the reason is that brightness can achieve basic construction lighting requirements, in this regard a lot of people in the use of lamps and lanterns can produce two big mistake.

500W
What are these two mistake?
First is everyone always thought that the greater the power, the higher the brightness, but the actual brightness is depends on power and luminous efficiency. On the basis of same power , luminous efficiency is higher, the total luminous flux is big.

Construction site now use 1500W metal halide lamp (light emitting Angle: 120 °) ,its total luminous flux is: 13500 LM, after secondary light distribution of lamps and lanterns will loss a large part (loss: about 50% of luminous flux), combined with infrared and ultraviolet (uv) content (about 20% -30%) , 1500 w metal halide lamp available luminous flux about 45000LM.

And TEK lighting LED stadium light, using good quality chip, the single side of the light, through the professional lens to disperse the light, basically the light does not wear out. Photoelectric detection report shows that the luminous efficiency of LED stadium light is greater than 130LM/W. The total luminous flux of the 500W LED stadium light is: 48000LM。

So the 500W LED stadium light can replace the 1500W MH.

Another mistake is that, compared with LED stadium light, the price of MH is relatively cheap, based on the requirement of brightness.
1500W LED stadium lamp


Take a lamp for example, each lamp works 12 hours per day, 0.8$ per hour calculation. Compared with the above electricity fee, a LED stadium light can 1.42 months to reach return on investment from the MH, which has not been added to the maintenance cost of MH, and the bulb will be damaged and replaced.

As mentioned above, it is fully proved that the 500W LED stadium light can replace the 1500W metal halide lamp.

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 can form a

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 as to realize the uniformity of illumination.

Rule of thumb: what are the installation instructions of DALI LED high bay light?

Image
DALI LED high bay light , also known as LED warehouse light, mainly used in factory workshop, warehouse, exhibition hall, etc., have gradually entered homes, because it is using the latest LED lighting energy saving technology, high reflectivity, high power, high utilization rate of light source. But good lamps and lanterns need specification installation, to highlight its advantages, below for everyone to explain the DALI LED high bay light installation: 1，Define DALI LED high bay light installation height according to the lighting environment, because the environment will change the reflection efficiency of lamps and lanterns. Usually the height of DALI LED high bay light  should be above 5 meters, thread is not close to the lamp shell. If installation height is less than 3 meters, protective measures must be taken to prevent a vehicle to touch. 2，TEK DALI LED high bay light protection class is IP65, choose waterproof transformer, chip packaging place with high temperature resi
