Nowadays, the replacement of traditional incandescent lamps with LED lights has become a trend, and it is an absolute process. But now many consumers do not know how to choose LED lights for a full purpose, that is, they don’t know what kind of LED lights to buy? , price, life, quality, etc.
Brand: There are too many brands of energy-saving lamps on the market, and the average consumer is a product that believes in big brands. This is a habit of customers. However, some small brands are also very prominent. Commonly used brand choices are NVC and Philips Lighting.
Price: Different brands, the price is definitely different, the better brand price is definitely higher, but consumers are also more convinced of the big brand's products. This requires consumers to choose their own situation. Generally, the moderate price can choose a comparison. Good led energy-saving lamps.
Lifespan: Each machine series is different, the service life is different, the shortest is more than 4,000 hours, the long is more than 10,000 hours, or even longer.
Quality: Only the manual can be seen. The cost structure of L ED lamps has been continuously improved with the development of packaging technology, carrier board design and heat dissipation module structure, and the cost has also decreased with the development of technology and market demand.
Also need to pay attention to the following aspects:
A look at packaging and trademarks
Generally speaking, the quality of the trademark printing of high-quality products is good, the font is clear, it is not easy to fall off, and it is wiped with a soft damp cloth. The mark is clear and identifiable, it is not easy to wipe off, and there are trademarks of manufacturers and related certification marks. Counterfeit products have poor printing quality, fuzzy fonts, easy to erase, no manufacturer's trademark and related certification marks.
Second, look at the appearance of LED tubes
The plastic shell of the lamp must be selected from the flame retardant type of engineering plastic. Ordinary plastics are easily deformed and flammable, and are prohibited from being used in the production of energy-saving lamps. The two can be easily discriminated from the surface. The latter surface is smooth and shiny, and the surface of the former has a texture similar to frosted glass.
3 three to see the temperature at work
When the LED energy-saving lamp is in normal working condition, its temperature rise should be very low. Otherwise, the LED energy saving lamp has a very short life. At the same time, when the energy-saving lamp is lit, there is a rapid flashing, or it is very glaring, indicating that the energy-saving lamp has quality problems.
4 four to see the startup performance
LED energy-saving lamp startup has two characteristics: First, the higher the temperature, the easier it is to start; the second is that the lamp is turned off and will not flash.
5 five to see the interference situation
When buying a lamp, look at the mark on the package to pass the national electromagnetic compatibility test. Second, bring a medium-short-wave radio. When the lamp is working, put the radio nearby. The lower the noise is, the lower the noise is. The electromagnetic compatibility of the lamp under test is better.
