LED bulb purchase four steps

The latest technology of a 7W all-round LED bulb is equivalent to a 60W incandescent lamp, and energy saving of more than 85%, the service life of up to 15 years, can be quickly switched 50,000 times, eliminating the need to change the lamp frequently. With the admiration of green and energy-saving life, LED bulbs, which are known for their energy saving, environmental protection, bright light and long life, have become the first choice for lighting in more and more ordinary households. However, in the face of a variety of LED bulb products, how should consumers choose?
The first step: product packaging details
For regular LED bulb products, there must be parameters such as parameter indicators, manufacturers, places of origin, and contact information on the product packaging. Through product packaging, consumers can first understand the most important buying factors such as brightness, light color, energy saving and service life, so as to correctly choose the product that suits them. If there is no such mark on the product packaging, it is an informal product, and the quality of the product is difficult to be guaranteed. It is difficult for the consumer to find the damaged product and the after-sales service. Therefore, consumers should carefully read the product packaging before purchasing LED bulbs.
Step 2: Pick up the bulb and watch it carefully
After reading the LED bulb product packaging, it is time to take out the light bulb to look at it, touch it, shake it, and measure it. First look at the appearance of the light bulb, its appearance should be smooth and uniform, no scratches; secondly, touch the surface of the bulb with your hand, the surface should be smooth, no obvious feeling of stabbing; again, shake the bulb vigorously, internal There should be no abnormal noise. If there is noise inside, it may be because the internal components of the lamp are not fixed or have debris, which may easily cause short circuit of the internal circuit of the lamp and damage the lamp. Finally, the merchant is required to light the LED bulb in a relatively dark environment. Observe the color and brightness of the light, and whether the light emitted by the bulb is stable, the light color is uniform, and the light is comfortable to the eyes.
The third step: both safety and environmental protection
As a kind of household appliances, LED bulbs are the most important safety. Therefore, consumers must choose LED products that have obtained the national product quality certificate. Be sure to check the product safety certification (such as GB certification and CE certification). Only products that have obtained safety certification are guaranteed in terms of safety, performance and quality. These marks are usually found on the product label inside the product packaging or box, and consumers should check carefully when selecting LED bulbs.
Green environmental protection is also an important factor to consider when purchasing LED bulbs. Qualified LED bulbs do not contain infrared or ultraviolet radiation, and do not contain mercury and other substances that may be harmful to health. They will not cause harm to the environment when discarded. For consumers who are increasingly concerned about environmental protection, pay attention to the relevant logo on the product packaging when purchasing.
The fourth step: comprehensive consideration of needs first
The space environment of each family is different. Consumers should choose the appropriate LED bulb according to the environment, not the brighter the better, the more expensive the better. In addition, the brightness of different places such as living room, kitchen, bedroom, bathroom, etc. is different. Only the LED bulbs with different brightness or light color can be used to create a home lighting environment that is comfortable, warm, and clear.
