How do you choose the right LED corn light As a consumer ?

The use of LED corn lamps is becoming more and more extensive. What should we be careful about in the process of using LED lighting?As a consumer, how do you choose the right lighting?

First, the six kinds of parameters that judge LED corn lamp are good and bad:
1, the luminous flux unit is the lumen (lm) ,note: the luminous flux directly decided by chip brands.
2，The color temperature (k) unit is kelvin.
3，The color index (RA).
4，Light source efficiency (lm/w).
5，The power factor of the power supply.
6，Heat dissipation.
Refer to the above 6 parameters, basically can decide a lamp is good or bad!
LED corn
Second, power selection
LED corn bulbs are the most common home power of 3W, 5W, 7W, 9W, engineering with 12W, 18W, 21W, 24W, even greater power, 40W, 80W, 120W, 150W, etc. 3W LED corn lamps are used for the large chandeliers, lamps, and bedside lamps in the living room.5W LED corn lamps are commonly used on floor lamps;The 7W LED corn lamp is used in the garage, the nanny house and so on. The greater power LED corn light is used in industrial lighting.

Three, lamp head choice
The commonly used lamp holder has E27, E14 etc. Screw lamp holder, the E27 is the most commonly used lamp holder.

Price analysis
For example, LED corn lights can be divided into: chips, aluminum plates, shells, and power supplies.Each section has different brands, different batches, different prices.

So how do we identify it?
Let the manufacturer take out the test report and see the five parameters.Looking at the shell, it determines the life of the lamp of the LED corn light.The look is the same, the thickness of the aluminum determines the price.

Color temperature choice
Warm white (2,800-3500K). Reach warm effect, warm tone.

Nature white (4000-4500K) Day white (5,000 to 5500K) is Cold white (6000-6500K). LED corn light is clean and neat, cool and is used more in summer.

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...
