There are many models of energy-saving lamps on the market, and the prices vary greatly. Some only need 7 or 8 yuan, and some need 20 yuan. In the face of all kinds of lights, how can consumers choose cost-effective energy-saving lamps? The Municipal Quality Supervision Bureau has made a move to the vast number of consumers.
Brand and certification are the first guarantee for the quality and safety of energy-saving lamps. Therefore, the first step for citizens is to carefully look at the brand and recognize the logo. The easiest way to buy energy-saving lamps is to choose products from well-known brands and purchase them in a mall or lighting franchise store that specializes in lighting. At present, the country's certification of energy-saving products is centered on safety and energy conservation. There are two types of certification marks: “CQC†(safety certification) and energy efficiency label. Products that have obtained national safety and energy certification should be selected.
Of course, the quality of energy-saving lamps can also be checked by checking information and looking at the appearance. The Municipal Quality Supervision Bureau reminded consumers that the quality of the products can be checked through the samples, product packaging and information on the instructions. The information includes relevant information of the production enterprise (such as factory name, factory address, etc.), relevant indicators, product implementation standards, etc. Good energy-saving lamps are usually clear and easy to identify and adhere firmly, and the writing and pattern should not be blurred or overlapped. In addition, viewing the appearance of an energy-saving lamp is also the most common and important method to verify its quality. A good energy-saving lamp should be smooth and clean, no bubbles, and the phosphor coating in the lamp should be fine, no particles, and even white; the lamp cap and the lamp should be in a vertical state, and should not be inclined; the contact surface between the lamp cap and the power source should be smooth.
If you are not at ease, consumers can experience it to check the quality of energy-saving lamps. For example, rotate the lamp head clockwise or counterclockwise to observe whether the lamp cap and the lamp body are loose, and shake the energy-saving lamp by hand. If the lamp tube and the plastic part are firmly connected, there will be no sound; the energy-saving lamp can also be checked for power-on. After turning on the light for 5 seconds, turn off the 55 second again to observe the condition that the filament is black and yellow. Generally, the energy-saving lamp without black and yellow is better. In addition, consumers can also observe the lighting of the lamp at the moment of power-on. Under normal circumstances, the light bulb is slightly dark first, and after a few seconds, it suddenly becomes very bright. Such a lamp has a longer life than a lamp that becomes brighter immediately after being energized.
