How Many Watts do Insignia TVs Use?

As stated earlier, 32 inch to 75 inch Insignia TVs use between 29.9 watts and 236.5 watts, on average.

The average power for all of the Insignia TVs studied was 103.5 watts when in On mode.

It’s important to realize that the amount of power an Insignia TV uses will depend not only on the screen size but the type of backlight LED technology used.

We created the following chart to help you see how Insignia TV power increases as screen size gets larger.

It’s easy to see the trend between TV wattage and TV size, however, it’s worth mentioning that larger TV screens tend to have high resolutions like 4k (2160p) and use more power.

The Insignia TV watts almost increases linear as the screen size goes up, other than the 75 inch TVs which use a lot more power!

It’s very important to remember that the numbers here are the average of the typical power consumption numbers reported by Insignia. They also provide the maximum power consumption numbers for most products and that can be two to three times as much as the typical power!

The chart below shows the minimum, average and maximum TV wattage for the Insignia TVs we reviewed.

Most screen size classes only had one TV in them, so there wasn’t any variation in the information provided. Regardless, even for the few TV sizes that had multiple options, the power requirements were very similar.

How Much Electricity Does a Insignia TV Use Per Hour, Month and Year?

The amount of electricity used by any modern TV in an hour is very simple to calculate if you know how much power is uses in On mode. You simply take the wattage and divide it by 1000, which gives you the amount of energy in units of kWhs.

So, for the typical 65 inch Insignia TV, which uses 157 watts to operate, it would take 157 watts divided by 1000 to get 0.157 kWh of energy used in 1 hour.

In order to accurately calculate how much electricity a TV uses in a month, you need to estimate the amount of time the TV is going to be on and off.

However, the Energy Star standard has determined that 5 hours with the TV in On mode and 19 hours with the TV in Standby mode, is the norm for households.

Therefore, you can determine how much energy is used in a day by multiplying the hourly power times 5 and then adding that to the standby mode power (0.5W) times 19 hours.

You simply take that daily power much and multiply it times 365 to get your yearly TV electricity average!

If you have a specific TV, or even your own TV at home, and want to know this number, then simply look-up the energy guide online, or you might even find the yellow label on the back of the TV.
