How Many Watts Does A Projector Use? A Guide To Projector Wattage

The projector comes with many benefits. With the development of technology, projectors today have become diverse in design, inexpensive, and can save energy.

So how many watts does a projector use? This figure ranges from 50 watts for the simplest projectors to 800 watts for the largest. 

The power consumed varies a lot when it comes to projectors. This article will compare the power consumption of some varieties of this device. 

We also instruct how to measure its electricity use. Stay tuned for the next content!

How Many Watts Does A Projector Use?

There are multiple kinds of projectors available on the market. Each works on a different power consumption degree. 

To generalize, we will go through the most popular models, including the battery-powered, LED, DLP, and LASER projector. 

ModelEstimated Electricity Consumption (Watts)
Battery-powered10 to 70
LED30 to 150
DLP150 to 350
LASER> 250

Battery-powered

Battery-powered varieties, often known as portable projectors, are a pretty new category. Depending on its performance and size, the project can use from 10 to 90 watts of electricity.

It is pretty small and affordable. The manufacturer, though, cannot offer all of the functionality included in a standard projector. 

As a result, characteristics like a larger screen, strong light supply, and decent sound quality are missing from your little projector.

LED

LED projectors provide the best of both worlds: the portability of battery-powered models and the functionality of traditional ones.

LED products use LEDs as their light source. Hence, they require very little power, which means they won’t raise your electricity expenses.

These projectors can use anywhere from 30 to 150 watts, depending on the functionality and specs of the projector.

Most LED projectors are affordable, with prices starting at about $300. Nonetheless, a large number of these devices use less than 100 watts of electricity.

DLP

DLP devices take advantage of the earliest projection technology still in use today. Even entry-level projectors have 5 to 8 times the brightness of LED devices.

The most significant disadvantage of a DLP projector is its high power consumption. DLP projectors are famous for their high power consumption, using anything from 150 to 350 watts on average.

The power consumption of a DLP projector varies depending on various factors, including projection technique, source of light, projection set, and equipment.

LASER

LASER projectors are a new projection technology that eliminates many of the LED and DLP projector’s problems.

To display an image on the projection screen, this model employs LASER beams as its light source. LASER projectors use LASER technology, which is entirely safe. It can work for a longer time without any problems.

However, LASER technology demands a lot of power. In most cases, the projectors consume upwards of 250 watts under normal conditions.

How To Measure Project Electricity Consumption?

You can measure how much power your project uses up with these steps:

Identify the projector’s capacity

The first step is to figure out how many watts your device takes to operate. You can check the label of your device to find out its capacity.

Alternatively, you can check this information on the internet. It would be best to visit the vendor’s or developer’s website.

Keep in mind that the projector power shown on the label is in watts per hour. It implies that if your display has a 50W rating, it will require 50 watts per hour to run correctly. 

Estimate the watt-hour 

A simple formula can help you calculate the number of watts utilized by your projector: 

(The project’s power capacity) x (the number of hours you run it per day) = The number of watts spent a day.

Considering a 150W projector utilized for two hours every day, we have (150) X (2) = 300 (Watts).

As you can see, the calculation is simple. It provides you with an exact estimate of your projector’s daily power usage. In this case, a 150-watt projector active for two hours will consume 300-watts every day.

Convert watts to kilowatts

Rather than watt-hours (WH), utility providers will bill you in kilowatt-hours (kWh).

If you want an accurate result of how much electricity your projector uses per month, you’ll need to convert watts to kilowatts. Since one kilowatt equals 1000 watts, we’ll have the formula:

(Device consumption in WH) / 1000 = (Device consumption in kWh)

Using the example of a 150W-projector, we can calculate its power consumption in kWh like this: 150 / 1000 = 0.15 (kWh)

Check the bill

You need to understand the utility company’s per kilowatt price to get an economic knowledge of your electricity use.

Many firms will list this on your power bill. If you can’t see the rate, contact them or visit their office to verify.

Calculate the monthly power consumption

Finally, you can calculate the electricity consumption of your projector every month. Here is how to do it:

Estimated monthly consumption = (Daily consumption) x (Days in a month) = 0.15 x 30 = 4.5 (kWh).

To expect how much you have to pay, use this formula:

Consumption cost = (Estimated monthly consumption) x (Utility office charge for one kWh rate) = 4.5 x 0.5 = $2.25.

So, you may pay $2.25 per month to run your projector. 

The Bottom Line

The amount of electricity required for your projector varies depending on the model. While the battery-powered model saves the most power, the LASER with the highest cost offers the most advanced technology.

You can also measure the projector wattage on your own with the steps we have shared.
