How do I choose a LED panel light?

LED panel lights are deeply loved by consumers for their high efficiency, energy saving, bright and uniform light, ultra-thin and ultra-light, stable and durable characteristics. It can be widely used in hotels, conference rooms, factories, schools, hospitals, residences and other places that require energy-saving and high color rendering index lighting. However, in view of the current vicious price competition in the ETL panel light market, the quality of LED panel lights varies greatly, and how to identify products has become a problem.


The following will provide you with some reference basis for choosing LED flat lights:

The power of the LED light

Material and structure affect the heat dissipation of the LED panel light 

Chip quality and packaging technology

Drive power is the core of the life of the bulb 

The power of the light

The low power factor indicates that the driving power and circuit design used are not good, which will greatly reduce the service life of the lighting. The level of power factor can be detected by ‘power factor meter’. Generally, the power factor of exported LED panel lights is above 0.85. If the power factor is less than 0.5, it is a substandard product or junk product. Not only the life span is short, but the actual power consumption is about twice as high as the nominal, and there is no power saving advantage at all. Another method is to use an ‘ammeter’ to detect two similar products with the same nominal power. The larger the current and the larger the current harmonics, it means that the actual power consumption is greater, and the less power is saved. At the same time, the current is unstable, which is detrimental to the life of the lighting.

Material and structure affect the heat dissipation of the LED panel light

The heat dissipation of LED panel light is also very important. For lighting with the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads will work at high temperatures, the light decay will be great, and the life of the lighting will be reduced. At present, the main heat dissipation materials used are copper, aluminum, and PC. Copper has better heat conduction than aluminum, and aluminum has better heat conduction than PC. At present, aluminum is generally used as the most heat sink material. The best is insert aluminum, followed by car aluminum, and the worst is cast aluminum.

 

Chip quality and packaging technology

The chip quality determines the brightness and light attenuation of the lamp beads. Good lamp beads not only have high luminous flux, but also low luminous decay. With the same lamp bead power, the higher the luminous efficiency, the higher the brightness. With the same lighting brightness, the lower the power consumption, the more energy can be saved.

 

Drive power is the core of the life of the bulb

The service life of the power supply is much shorter than other parts of the LED panel light. The life of the power supply affects the overall life of the lighting. The theoretical life of the lamp bead is between 50000 and 100000 hours, while the life of the power supply is between 20000 and 30000 hours. The design and material selection of the power supply will determine the service life of the power supply. The higher the power efficiency, the better. The higher the value, the smaller the power consumption of the power supply itself, and the larger the output power. The appearance of the power drive with aluminum alloy is better than that of engineering plastics. First, it has better heat dissipation. Second, it can effectively protect the parts from being crushed and loose during transportation and use, and reduce the failure rate of the power drive.

 

We hope this article has helped you understand more about LED panel light and how to choose LED panel lights. We have a wide range of products. We have 4 inch and 6 inch led panel light. We have 9w and 15w panel light. And we also have downlight for indoor lighting. Our product all passed the ETL test, which are all good ETL panel light.
