Around 23% to 34% of people buy them for low prices. They provide future technical problems due to less investment.

How to calculate the electricity use of a projector?

There are two ways to calculate the total electricity use by a projector. The calculations offer precise data, and you can estimate the expenses. 

The electric and automatic meters are beneficial to access the results instantly. 

Calculations and conversions

Check the wattage of your projector through its label. In addition, several manufacturing companies offer information about watts and electricity use per day. 

The information is about the use of electric current every hour. To get the watts per day, multiply the number of watts by the hours. 

It is one of the simplest yet precise methods to get the actual results. In those situations, when you want to access the electricity use monthly, convert the total watts onto kilowatts. 

The electric companies cost you for the kilowatts because it is a bigger unit. So divide the number of you consumed watts by one thousand and get the kilowatts.

Multiply these numbers with the days, and the result is the total watts consumed. In those situations, when you want to know the total cost per kilowatt, check the recent electricity bills. 

It helps you to calculate the precise bill, and you can handle it according to your budget. 

Use of meters

The electric meters of homes and offices are appliances that show a reading of electricity consumption. Use this data and estimate the usage. 

In other situations, the digital tools help in the reading of power use. It is a measuring device to obtain the used watts. 

Attach it with the socket and connect the output of the projector into the equipment. The obtained data is in a similar unit and requires conversion in kilowatts as above. 

In those cases, when you lack these tools, then use the manual method. First, turn off all appliances and hold the meter at one point. Then, remove the plug from the electric power center.

Take calculation with a duration of 1 to 2 hours. Repeat this process 2 to 3 times to get precise information. Then, count these values manually and write them down.

What is electricity consumption by different parts of a projector?

Various parts of the gadget contribute to the picture production and light spread. These side parts have one of the most significant effects on the image. 


The options are available in the form of light lamps for the projectors. They are a protection hub for tiny bulbs. Moreover, they work with electric power without any disturbance in the current passage.

They use the highest level of electricity due to their design and functions. For example, on average, a light lamp takes around 310 watts to 504 watts every hour.

The limits vary according to the setup use, but they remain under specifications. These lamps have various levels of design and power consumption enhances. 

The home theater uses smaller lamps. However, the cinemas comprise massively large systems, and they are known as Xenon lamps.

They utilize one of the highest ranges of watts every hour. On average, the Xenon projector consumes around 6200 watts to 15500 watts per hour.


Its bulb varies from model to model, and they consume less electricity. The light-emitting diode bulbs use around 40 watts to 105 watts per hour. 

Few of them have laser technology, and it is a built-in feature of a light source. On average, the laser bulb uses approximately 89 watts to 205 watts per hour. 

It takes more energy, but the results are bright and clear with laser light sources. The options that contain halogen in them are also effective for home setups.

They use around 170 watts to 220 watts every sixty minutes. 

Examples of projectors with their electricity use per minute, per thirty minutes, per hour, per day, per month, and year

These are the projectors with their estimated maximum and minimum electric consumption per hour. 

The data offer a layout for further calculation, and you can reduce the usage in case of high bills.
