How to judge the quality of led lighting? How to judge the quality is what you need to understand when buying led lights. The emergence of leds facilitates the lighting in our lives, but with the gradual expansion of the market, inferior led light manufacturers are also appearing in large numbers in the market, so how to judge a led light Is it good or bad? Let’s tell everyone
Quality Judgment Guide 1. Look at the packaging and identify the trademark.
my country is mandatory for LED lighting manufacturers to mark the following on the outer packaging: rated voltage, voltage range, rated power, and rated frequency. Generally speaking, the trademarks of high-quality LED products have good printing quality, clear fonts, and are not easy to fall off. They have the manufacturer's trademark and related certification marks. Fake products have poor printing quality, blurred fonts, easy erasure, and no manufacturer’s trademarks and related certification marks.
Quality Judgment Guide 2. Use your eyes to recognize and cover with your hands.
The real LED energy-saving lamp uses three primary color tubes, the tube is white, and it is whiter by covering it with your hand. In addition, from the point of view of the lamp tube, you can put multiple lamps together for comparison. The shape and size of the lamp tube are more consistent, mostly by machine bending, and most of them are mass-produced products. The product consistency is good, and the quality is good. It is easier to obtain guarantee and better interchangeability during maintenance. Of course, there should be no cracks, looseness, and traces of prying between the interfaces on the appearance. During installation and disassembly, the lamp cap should not be loose or tilted.
Quality judgment guide 3. Look at the parameters, anti-glare.
The main parameters of LED lamps, especially high-power LED lamp beads, are luminous efficiency, color rendering index, color temperature and so on. Luminous efficiency represents the energy-saving effect of LED lights, and must be greater than 80 LM/W to meet the requirements; the higher the color rendering index, the better the color rendering of the light source. Generally, 0.8 is enough. For painting work, there are higher requirements for the color rendering index; color temperature will directly affect the lighting effect and human health, especially as a reading lamp or bedroom night light, it is best to use 2700K low color temperature LED lamp. If there is glare, it will have potential adverse effects on children in the home. In order to reduce glare, it is simply the same brightness. The larger the light-emitting area, the better.
Quality Judgment Guide 4. Look at the place of production and choose the company.
The largest clusters of China's LED industry are the Pearl River Delta and Southern Fujian. These two regions have concentrated many outstanding LED companies, whose products are exported to foreign countries in large quantities, and their quality and technology are relatively mature. In addition, companies that choose to produce LED lamps can also make comprehensive judgments based on whether they are registered, whether they have certification, whether they have a formal website, relevant media reports, and user feedback.
