The average service life of fluorescent lamps is 1000 hours. The glass bulb of fluorescent lamp will turn black after a long time, and will burn out after a while, because the filament used in fluorescent lamp is tungsten wire. After being electrified, the temperature in the bulb is as high as 2000 degrees. Long-term high temperature makes the surface of tungsten wire and glass shell turn black slowly and become more and more opaque. The life of energy-saving lamps is as long as 8000 hours, and the light efficiency is 6 to 8 times that of ordinary bulbs.
2. Different prices:
The market price of fluorescent lamps ranges from 25W to 100W, and the price of energy-saving lamps ranges from 8 yuan to tens of yuan, which is several times that of fluorescent lamps.
3. Different performance:
Although the fluorescent lamp has low light efficiency, it has good light color and light collection performance, convenient installation and use, and can be started immediately with low cost. It is the largest output and the most widely used electric light source. With the continuous improvement of filament materials, filament structure and filling gas, the luminous efficiency of fluorescent lamps is also advancing with the times.
Energy-saving lamp, this kind of light source only needs to consume the electricity consumption of ordinary incandescent lamp 1/5 to 1/4 on the premise of achieving the same light energy output, thus saving a lot of lighting electricity and expenses. Compared with ordinary fluorescent lamps, it can save 70-80% energy, start quickly at low voltage, and has no stroboscopic; Pure tricolor phosphor tubes are used to make the lighting objects bright and fresh; Novel design, a number of patented technologies, the bracket is made of aluminum alloy, which is compact and beautiful, never rusts, environmentally friendly and flame retardant.
Matters needing attention in purchasing energy-saving lamps
1, choose energy-saving lamps depends on the packaging:
The first thing you see when you get the energy-saving lamp is the outer packaging. The package must have the brand, production date, voltage and rated power, manufacturer's address and telephone number, etc. These materials are complete and qualified, followed by 3C marks or other safety marks.
2, choose and buy energy-saving lamps depends on the lamp body:
The surface of the lamp body should be printed with necessary information, such as voltage, frequency and applicable power supply. Secondly, the appearance should be smooth, the workmanship should be fine, the phosphor coating in the lamp should be fine, there should be no particles, the color should be uniform, there should be no slag in the lamp tube when shaking, and the quality should be good. Also pay attention to the stability of the connection, you can install and remove the lamp cap many times to ensure that the lamp cap is not loose.
3, choose and buy energy-saving lamps to have a try:
Shops that specialize in selling lamps generally have try-on lamp holders. You can just observe the use status. Some people think that the first ignition of energy-saving lamps. Actually, it's not. The filament preheating circuit is often installed in elegant lamps, and there is a delay of about 4 seconds after it is turned on. Therefore, the first ignition should be understood as the minimum flicker after opening, and there is no red light at the root of the lamp. Secondly, compare the temperature of the lamp body after disassembly, and the lower the temperature, the better.
