Does A Projector Use More Electricity Than A TV? All Details That You Need!

You’ve probably seen projectors in classrooms and conference rooms, but have you ever wondered how much electricity they use? Does a projector use more electricity than a TV? The answer may surprise you.

According to the Environmental Protection Agency, TVs only use about 3 watts of power when they are on. In contrast, projectors consume around 200 watts of power while projecting an image on the screen! So what’s the deal with this big difference in power consumption?

If you’re considering buying a new TV or projector, you might wonder how much energy each device uses per hour and whether one will save you more money than the other in the long run. We can’t make this decision for you, but we can give you some context to help you think through the best option when choosing between these entertainment devices.

Projector vs TV Energy Consumption

Do you know how much power your projector is consuming? Are you still amazed at how it compares to your TV? Here’s a quick rundown of projector power consumption in watts and how it compares to televisions.

A standard projector consumes around 150 to 800 watts per hour to deliver the optimal output, making you decide the final output to be around 300 watts. If you compare the output with the TV screen, it will take around 80 to 300 watts which is low according to the projector screens.

Factors that affect the Amount of Electricity Consumed by Projectors

While deciding on the projector’s power consumption, multiple factors will take part equally to give the final output. The size of the projector is one of the most vital role-playing factors you cannot ignore. The bigger the projector, the more electricity it will use. Other factors include the type of projector (LCD, DLP, LED), the resolution, and the brightness.

So, does a projector use more electricity than a TV? As we elaborate on in our above article, it depends on the projector size. Generally speaking, a projector consumes more electricity than an average TV screen in our home.

1. Screen Size

One main factor determining how much electricity a projector uses is its screen size. A projector with a larger screen will use more electricity than a projector with a smaller screen. For example, a projector with a screen size of 100 inches will use more electricity than a screen size of 50 inches.

2. Quality of picture

Most people believe that projectors consume more electricity than TVs, but this is not always the case. It depends on the wattage of the projector and how it operates.

For example, if you are using a projector to watch Netflix shows, it will use more electricity than if you are using a TV. However, if you are using a projector for business presentations, it may not use as much electricity as a TV.

3. Brightness

One of the necessary specs to consider when choosing a projector is its brightness. This measure in lumens, and the higher the number, the brighter the projector will be.

If you are using a projector in a dark room, you won’t need as many lumens as you would if you were using it in a well-lit room.

4. Color Scheme

Most people believe that a projector uses more electricity than a TV. After all, a projector constantly projects an image onto a screen, whereas a TV only has to display one static image. However, this is not always the case. It depends on the projector’s wattage and how much electricity the TV uses.

How Can One Reduce the Amount of Electricity Consumption?

You can reduce electricity consumption by limiting your usage hours or just shut down when you are not using it. You can unplug the projector from the power outlet.

Additionally, you can use a power strip to plug in the projector and turn off the power strip when you are not using it. Finally, you can use a lower-wattage bulb in your projector.

Make sure you choose a projector with an Energy Star rating if you want to conserve electricity. It is also worth noting that newer models of projectors are more energy efficient than older models.

It is essential to replace your projector at least every six years because newer projectors are more powerful and less energy intensive.


Is it worth getting a projector over a TV?

The truth is, it depends on a few factors. First, let’s look at what uses more electricity – tv or projector. A projector typically uses around 200 watts of power, while a TV can use anywhere from 50-400 watts, depending on your size and type of TV.

How much electricity does a projection TV use?

How much electricity your projection TV uses depends on a few factors, including the screen size, brightness, and power management features. Most LED TVs have rated power between 60 watts to 150 watts.

Can you use the projector for everyday TV watching?

You can use a projector for watching your daily entertainment shows or movies. It will enhance the overall TV-watching experience by not paying a higher price than the high-end television screen. If you want the best energy efficiency in your home theatre setup, consider using a 55 or 60 LED TV instead of a projector.

Are projectors better than TVs for your eyes?

A projector’s Indirect light is much gentler on the eyes. You can reduce the damaging effect of the blue light produced by the TV screens. Some experts say that projectors are better for your eyes because they have indirect light.


In conclusion, does a projector use more electricity than a TV? It depends on the size of the projector and how many hours you use it per day. If you use a small projector for a couple of hours each day, it is unlikely that it will use more electricity than your TV.

However, if you have a large projector that you use for several hours each day, it is possible to use more electricity than your TV.
