The product is mainly composed of energy-saving lamp tube, PCB board, plastic shell plus lamp cap and packaging, but PCB board is invisible, and can be seen only when the energy-saving lamp is turned on

the English name of energy-saving lamp is usually energy saving lamp (ESL) or compact fluorescent lamp (CFL) or bulb (bulb)

>& gt;& gt; Link: seven points for attention in the purchase of energy-saving lamps

the product is mainly composed of energy-saving lamp tubes, PCB boards, plastic shells plus lamp caps and packaging, but PCB boards are invisible, and can only be seen when the energy-saving lamps are turned on. The main technical terms of electronic energy-saving lamps include: model, working voltage, wattage, lamp cap, color temperature, lumen, lamp tube, light attenuation, plastic, service life, etc., which will be explained one by one below

model:

generally, 2U series, 3U series and other energy-saving lamps can be seen in supermarkets. What does this mean? As we all know, the tubes of energy-saving lamps are U-shaped. Two tubes are 2U and three tubes are 3U. There is no big difference between other lamps of different shapes. The main difference lies in the power. Generally, the larger the wattage is, the longer the length is, and the thicker the lamp and plastic are

working voltage, in v:

refers to the voltage required for the operation of energy-saving lamps. Generally, 220V is used in our country and most countries in Asia (except Japan and South Korea), 230V is used in Europe, 240V is used in Australia, 110V is used in North America (the United States), Japan (South Korea) and most central and South American countries, and DC 12V is used mainly on ships or solar energy. In addition to voltage, the power supply also requires frequency, generally 50Hz or 60Hz. But frequency has little to do with energy-saving lamps. Generally, the energy-saving lamps produced by our company can work normally within the range of - 20% - 10% of the working voltage, such as 220V, so it is calculated according to this ratio as: 176v-242v, which avoids the failure of a large number of energy-saving lamps caused by voltage instability in some countries. One thing to declare: the more stable the power supply, the longer the service life; The less the switching times, the longer the service life

power Watt, in w:

power has two concepts: actual power and print power. Print power is usually a concept that you can see and most customers can accept; However, the actual power can't be seen and can only be measured by instruments. In order to prevent illegal manufacturers from falsifying, low power is passed off as high power, so as to save money (usually the lower the power, the cheaper the price). China has issued a national standard on energy-saving lamps, gb/t17263-2002, which stipulates that the actual power shall not be less than 85% of the print power. However, due to the different requirements of commodity inspection in different cities in China, the phenomenon of passing low power off as high power is still widespread

lamp cap base:

lamp cap refers to the head of energy-saving lamp, which usually has e27/e26/b22/e14. E27 is needed by most markets, and this kind of lamp cap is basically used in China; E26 is the United States and Canada; B22 refers to Britain and British colonial countries, such as India, Pakistan, Australia, etc; E14 is a small lamp cap. Materials include copper, iron, aluminum, etc., and the price ranges from high to low. The difference is that the iron lamp cap will rust after a long time, while the aluminum lamp cap is relatively soft

color temperature, in k:

refers to the color of light when the light is on, usually from 2700k to 7000K. The higher the color temperature is, the whiter it is. Visually, it looks brighter. In fact, it is not the case. There are also some professional English about color temperature. Warm color refers to 2700k, daylight refers to 6400k, cool daylight refers to 6500k-6700k, and so on. The color temperature has nothing to do with the price of the lamp. But it is related to production, such as 2700k, 6400k, 6500k and 6700k, which are commonly used, and the quantity limit is not very strict. For other color temperatures such as 4100k, the lamp supplier has certain quantity requirements
