Energy saving and emission reduction actions should start from small things, and it is easiest to buy and use energy-saving lamps, which can save money on electricity and protect our eyes. What is the price of energy-saving lamps? How to choose energy-saving lamps products?
What is the price of energy saving lamps?
At present, the price of an ordinary energy-saving lamp is about 50 yuan, and the price of LED lights is 200 yuan. With 50,000 hours of operation and Harbin’s residential electricity bill (0.51 RMB/kWh), the electricity cost of an ordinary energy-saving lamp is 382.5 RMB, i.e. (15 watts x 50,000 hours)/1000 x 0.51 RMB = 382.5; the electricity cost of an LED lamp is 229.5 RMB, i.e. (9 watts x 50,000 hours)/1000 x 0.51 RMB = 229.5.
However, under the 50,000-hour test, ordinary energy-saving lamps need to be replaced by 10 lamps. Assuming that a 50 yuan ordinary energy-saving lamps include 25 yuan for the lamp and 25 yuan for the lamp, then the cost of lighting 50,000 hours is 275 yuan (25 yuan × 10 tubes + 25 yuan = 275); while lighting 50,000 hours of LED lights need only 1, the cost of about 200 yuan. After 50,000 hours of lighting at the same time, the total cost of ordinary energy-saving lamps is 657.5 yuan, LED lights are 429.5 yuan. Thus, it seems that one LED lamp will save 228 yuan compared to ordinary energy-saving lamps. The savings will be multiplied by the total amount of lights used in each room.
Let’s see, at the same power, i.e. the same wattage, an energy efficient lamp is brighter than a regular CFL. Theoretically, the life of ordinary energy-saving lamps is about 5,000 hours, while the life of indoor LED lights can reach 50,000 hours. Theoretically, with 5 hours of electricity per day, it can last up to 27 years.

【Methods to buy energy-saving lamps
Energy-saving lamp method 1, choose a big brand
Buy electrical products must be purchased through the national 3C mandatory human certification and other related certification products, such as Philips PHILIPS, the United States General GE, Germany OSRAM, Weihai Beiyang, Sunshine Group, Far East, Jianhu, on the electricity, Siyang light bulb factory, etc., are very good old brand. Also has a particularly good reputation. Generally speaking, the big brands of products related to certification and packaging, instructions and manufacturer contact information will be relatively complete, while small manufacturers due to cost and other reasons fine-tuning, resulting in many problems.
Selection of energy-saving lamps method 2, test performance
For open once straight light type of light source is usually not recommended to buy, this type of light source is usually no preheat filament circuit, followed by the start of the lamp internal do not appear red light. If possible, the corresponding test on the regulator in the electrical store, you can settle the instructions on the instructions, the starting voltage to the minimum and maximum, respectively, to test the starting performance of energy-saving lamps under two different voltage conditions. Energy-saving lamps for temperature and induction characteristics of the
Selection of energy-saving lamps method 3, look at the working state
Ordinary incandescent lamp performance can reach the second step, but energy-saving lamps are much more demanding. The voltage of the energy-saving lamps to start a good input 250W continuous high-voltage work for 5 minutes to see if there is flicker and odor overflow, if not, it means that the quality is excellent.
Selection of energy-saving lamps method 4, see the interference situation
Electrical appliances are electromagnetic compatibility is China’s electrical appliances must pass the test project, in the purchase can carry a medium-wave radio, turn on the energy-saving lamps after the radio will be next to the smaller the electromagnetic noise that the better the electromagnetic compatibility.
Selection of energy-saving lamps method 5, look at the performance after work
In addition, the cooling at the end of the work is also the scope of the test, the lower the temperature of the lamp at the end of the work, the better; secondly, if the lamp appears black, it means that the quality is general, and the life expectancy is relatively short.
Selection of energy-saving lamps method 6, appearance acceptance
The plastic packaging of the lamp and other plastic shells must be made of flame-retardant materials, ordinary plastic in the case of high-temperature degenerative flammable, has been banned by the state for the use of lighting products. A simple way to tell. Energy-saving lamps packaging plastic is a texture similar to frosted glass, while the surface of ordinary plastic is relatively smooth and shiny. The shape and size of the lamp in one piece is indicative of machine bending and molding, the quality of the product will be better, and the maintenance and replacement will be more convenient. In addition, check whether there are cracks, loose, interface is pried and other traces.
