How much does a bulb consume?
Find out the energy consumption of different bulbs and tips to reduce lighting spending.
LED bulbs stand out for their energy efficiency and durability, which makes them a long -term investment.
Knowing how much consumes a bulb helps you make smart and sustainable decisions in terms of lighting, which can have both economic and environmental benefits. In this article, you will not only find how the consumption of a bulb is calculated, but also the difference in consumption between them and how much you can save with the LED bulbs.
1 Consumption difference between incandescent bulbs, low consumption and LEDs
Incandescent, low consumption (CFL) and LED bulbs are distinguished by their energy efficiency and energy consumption:
- Incandescent bulbs: they are the least energy efficient. They work by heating a filament until it emits light. However, much of the energy consumed becomes heat instead of light, which makes them less efficient. A typical incandescent bulb can consume between 40 and 100 watts of power.
- Low consumption bulbs (CFL): are more efficient than incandescent, but less than LEDs. The CFL operates by excitation of mercury vapor and produce ultraviolet light that is converted into visible light for fluorescent coatings. They consume less energy than incandescent to produce the same amount of light. A typical CFL bulb can consume around 9 to 15 watts.
- LED bulbs: They are the most efficient in terms of energy consumption. They use light emitting diodes to produce light and are able to convert most of the energy consumed into light, minimizing heat generation. A typical LED bulb consumes approximately between 5 and 15 watts.
2 How the consumption of a bulb is calculated
The calculation of the energy consumption of a bulb is carried out by multiplying its nominal (watt) power by the time during which it is on (in hours), and then dividing the result by 1000 to obtain consumption in kilowatts-Hora (kWh).
The formula is:
Consumption (kWh) = power (watts) × time (hours) / 1000
3 How much a light bulb spends all day
If we want to determine how much a light bulb spends all day, we simply multiply its power by the number of hours that is on for a day (24 hours), and then divide the result by 1000 to obtain consumption in KWh.
For example, if we have a 10 -watt LED bulb lit throughout the day:
Consumption (kWh) = 10 watts × 24 hours / 1000 = 0.24 kWh
4 How much is saved with LED bulbs?
Savings with LED bulbs can be substantial over time. Although LED bulbs can initially be more expensive than incandescent and low consumption, their energy efficiency and long shelf life result in long -term significant savings.
According to world statistics, LED bulbs consume more than 80% less than traditional lights. An easy and fast way to reduce your light bill.
It is clear: LED bulbs consume less energy and last much longer than the rest, which reduces both energy costs and bulbs replacement costs. In addition, a fact that we do not want to pass, is that having lower power, generate less heat, which can result in additional savings in cooling costs in environments where they are used in large quantity.
