How many specifications are there for energy-saving lamps?
The commonly used specifications of energy-saving lamps are 3W, 5W, 7W, 9W, 11W, 13W, 15W, 18W.
For household use, 9W and 11W are generally used for bedroom and kitchen lighting; 11W and 13W are used for living room lighting; 5W and 7W are used for bathroom lighting.
5-7W around 9 yuan; 9-11W around 13 yuan; 13W around 15 yuan.
Don’t buy cheap ones. Cheap ones have low brightness and short lifespan.
Pay attention when choosing the wattage of energy-saving lamps
We all know that lighting has a wattage, no matter what kind of lighting has a wattage The difference is that the wattage of the same lamp is also very different, and the price is also different according to the wattage. When choosing energy-saving lamps, many people think that the bigger the wattage, the better, because the bigger the wattage, the brighter. The higher the number, the better.
In fact, when choosing energy-saving lamps, many people do not understand the issue of wattage, and they are all blindly choosing. In fact, from a design point of view, the use of lights can also adjust the indoor atmosphere, etc., so when we choose, we should choose different wattages of energy-saving lamps according to the environment we use, such as in In the bedroom, we can not only choose some low-wattage, but also some energy-saving lamps of different colors; even if it is used on the desk lamp in the study, we don’t have to choose a particularly large wattage. If it is too bright, it will be harmful to us. Eyes are adversely affected.
If you only cared about the brightness of energy-saving lamps in the past, and did not consider other aspects, and you only chose energy-saving lamps with very high brightness, then you will be in the future. When choosing, you should pay attention to it. It will help you to change the wrong selection method in the past. It will not only allow you to choose the right energy-saving lamp, but also help your eye health more.
Energy-saving lamp wattage conversion
1W led lamp is equivalent to about 5W incandescent lamp, which is similar to energy-saving lamp. What I am talking about here refers to the “development trends of lighting sources” in the August issue of “Building Electric”.
1W led is equivalent to 3W CFL (energy saving lamp) equivalent to 15W incandescent lamp, 3W LED is equivalent to 8W CFL (energy saving lamp) equivalent to 25W incandescent lamp, other wattages and so on .
Generally speaking, 3w led bulbs are enough for a normal-sized living room. If the living room is larger, you can use bulbs of different wattages as needed, and larger bulbs are often used for huge displays Screen. There are also common mobile phone indicators in daily life, car tail lights and traffic lights are also often used LED lights. All in all, according to different needs, led bulbs of different wattages have been used in every corner of our daily life because of its powerful advantages.
ledLight bulb wattage conversion methods are as follows:
1. LED conversion efficiency per W = 70-80LM
For example: 8W led solar tube = about 560-600LM.
2. General daylight fluorescent lamp per W=30-40LM
For example: 20W fluorescent lamp=20*30=600LM
For example: 8W led The lamp is equivalent to a 20W ordinary fluorescent lamp. Tip: Refer to the above formula to know the actual wattage of the LED lamp you bought.
The above has introduced the wattage conversion scheme of led bulbs. If the wattage is marked on the bulb, it is not the actual wattage, because the marked wattage is based on the standard household use. To calculate the voltage, in fact, the voltage we use is not necessarily 220V, so it is necessary to convert it into the actual wattage.
