Light bulbs are an essential part of every home and every room has to have light bulbs to illuminate the room for us. Because of our current housing structure, we need light bulbs not only at night, but sometimes even during the day. Since light bulbs look smaller and they don’t consume as much energy as air conditioners, we don’t care much about the power consumption of light bulbs. However, when it comes to our electricity bill, the amount we have to pay because of the energy consumed by light bulbs cannot be ignored. In this article, we will walk you through the power consumption of light bulbs and the factors involved.
1. How much electricity does a light bulb consume?
A light bulb is a source of illumination that emits light and heat through electrical energy. It consumes less power for a short period of time, but for a long period of time, the light bulb needs to consume a portion of the power. For the power consumption of light bulbs, we usually do not use the survey method to roughly estimate, so that the results obtained are very different from the actual use. This is because the power consumption of light bulbs may be affected by other factors, such as the usage of different households, the duration of use, the type of light bulb, and so on.
In addition, we can also directly calculate the power consumption of light bulbs, light bulbs, such as only the function of lighting appliances, for such simple appliances, our calculations will be more accurate. When we calculate the power consumption of light bulbs, we also need to know the power of the bulb and the length of time the bulb is used.
The power of the bulb: many bulbs in the packaging or on the bulb itself will be by the power of the relevant data, which is the most direct method. However, if the outer packaging is missing, you will need to double check the wattage of the bulb at the end of the bulb. For the power of the bulb, we also organize some power of the bulb for you.
| Light bulb type | bulb type power |
| fluorescent light bulb | 5w , 8W, 13W, 18W, 36W |
| LED Light bulb | 3W, 5W, 13W, 15W, 18W |
| Incandescent lamp | 25W, 40W, 60W, 75W, 100W |
Length of time the bulb has been used: For the time the bulb has been used every day, you can just use a stopwatch to record it. This is also a more troublesome method. If the lamp you use is a smart socket that supports the timer function, you can use the accompanying APP to track the use time of the bulb. In addition to this, there is also a light bulb on the market with a built-in timer function, but this kind of light bulb is usually used to test the service life of the bulb, and it is not commonly used in the home.
Once you know the two important figures above, you can calculate the power consumption of the bulb. But you will also need to use the following formula.
Power consumption of light bulb = power of light bulb * length of use of light bulb
If you are using a light bulb with a power of 10W.
If you use a light bulb with a power of 10W, and the length of time the bulb is used in a day is 5h, then the power consumption of a light bulb in a day is 10W*5h = 50Wh.
If there are 6 light bulbs in your home, then your home needs to consume 300wh of light bulbs in a day.
2. How much money can I save by using solar system to power my light bulbs?
If you have installed a solar system in your home to provide electricity for light bulbs, you basically don’t need to invest other costs in the process of using the solar system, except for the cost of the solar system that you have invested in the first stage. This is because the solar system generates electricity as long as there is sunlight. This is equivalent to the cost you need to pay on the light bulb can be saved. However, the price of electricity in your area is the biggest factor in how much you can save. Let’s say the price of electricity in your area is $0.1/kWh. We follow the above a family in a day light bulbs need to consume 300wh calculation, you can save a day of electricity is $0.03, a month can save electricity is $0.9, a year can save electricity is $10.8.
3. Tips to reduce light bulb power consumption
Wipe the lamps regularly: When the lamps have not been cleaned for a long time, the lamps and the reflectors will accumulate a lot of dust, which will reduce the efficiency of the bulbs. Generally we recommend that lamps be cleaned at least every three months, which will ensure the output efficiency of the lamps.
Replacement of old bulbs: When the service life of the bulb reaches about 80%, its light output will be reduced to about 85%, so it is very important to replace the bulb regularly. Apart from improving the illumination of the room, it will also save electricity.
Choose light colors for ceilings and walls: Interior walls, ceilings and curtains should be in light colors to reduce the diffuse reflection of light, and even if your light bulbs are not high powered, they can still achieve sufficient illumination, which saves a lot of electricity.
Choose energy-saving bulbs: In the same lighting effect, incandescent lamps consume about twice as much electricity as LED bulbs, so we should choose energy-saving bulbs as much as possible to reduce the power consumption of bulbs from the root.
Conclusion:
Light bulbs are indispensable lighting tools in our lives. Due to their high frequency of use, it is important to understand the power consumption of light bulbs. When we understand the power consumption of light bulbs along with some of the tips we know to reduce the power consumption of light bulbs, we can reduce the cost of running the light bulbs. Moreover, using a solar system to power the light bulb is the best way to power not only the light bulb but also other appliances. So installing a solar system is a very good option.
