In today's pursuit of green and low-carbon life, household LED lighting fixtures have become the mainstream choice.
However, the quality of LED lamps on the market is uneven, and it is particularly important to choose high-quality LED lamps and lanterns.
This article will focus on this topic and introduce in detail the core elements of identifying the worst household LED lights, including but not limited to checking the packaging logo, light source quality, heat dissipation design, driving power supply and brightness stability, etc., aiming to help consumers make informed choices when purchasing and ensure that home lighting is both energy-efficient and safe and reliable.
To identify the worst of household LED lights, you can start from the following aspects:
Check whether the basic information of the product is clearly marked on the package, such as rated voltage, rated power, luminous flux, color temperature, color rendering index (CRI), etc.
The product packaging should have CCC or the safety certification mark of the corresponding region, such as UL and ETL certification in the United States, CE certification in Europe, etc., indicating that the product has passed the safety and quality standard testing.
The light source of high-quality LED lamps usually uses well-known brand chips, such as Wafer, Osram, Philips, etc., which have high light efficiency, good stability and long life.
Observe whether the lamp beads are arranged neatly, whether the color is consistent, whether there is a dead lamp or obvious color difference.
High-quality LED lamps will have a good heat dissipation structure, such as aluminum alloy radiator, thermal grease, etc., to ensure that the heat can be effectively dissipated when used for a long time, and avoid high temperature affecting the life of the LED light source.
High-quality LED lamps are usually equipped with constant current drive power supply, which can stabilize the output current and prevent the brightness and life of the light source from being affected by voltage fluctuations.
Check whether the power supply has EMC (electromagnetic compatibility) and safety certification to ensure that it is safe to use.
There should be no flickering at start-up, the brightness should be stable without obvious fluctuations, and there should be no overheating.
The shell should be flat and smooth, with edges and cracks, plastic materials should be odorless, and metal parts should be free of rust.
The lampshade has good light transmittance, and there is no obvious deformation or scratch.
Test the actual lighting effect to see if the light spot is uniform, there are no dark areas or hot spots, whether the color temperature meets expectations, and whether the color rendering is good.
Although not absolutely, products that are too cheap may have quality problems. Choose well-known brand LED lights, the quality is more guaranteed.
Through the above control and field tests, you can comprehensively judge the best of an LED light.
When purchasing, don't ignore the product parameters and certification documents provided by the salesperson, and try to choose formal channels to buy.
Only according to the actual needs, and then comprehensively consider the above points, you will be able to find a satisfactory LED light.
