Do Neon Signs Use a Lot of Electricity? Real Costs Explained

Do Neon Signs Use a Lot of Electricity? Real Costs Explained

Table of Contents

Neon signs are famous for their vivid glow, making them very attractive and noticeable. This is why a lot of people believe they need to use plenty of electricity. That's a common question asked by our customers who plan to install such a product at their homes or businesses.

The truth is entirely different.

Unlike regular devices, which burn through electricity in one way or another, neon signs do not require burning any power source whatsoever. They simply make use of electricity to make some gases excited or, in the case of LEDs, light-emitting diodes. Let's understand exactly how much electricity neon signs use, what it costs to run them, and how you can optimize energy usage without sacrificing visual impact.

How Neon Signs Actually Use Electricity

To understand power consumption, we first need to clarify how neon signs work.

Traditional Neon Signs

Old-fashioned neon signs consist of glass tubing that is charged with gas such as neon or argon. The passage of electrical current through the gas leads to the production of light. This sign technology requires transformers and has relatively high voltages.

LED Neon Signs 

At CRAZY NEON®, we focus on LED neon technology. These display signs use flexible LED strips that are housed in tubes for creating an authentic neon effect.

Some benefits include:

  • Reduced electricity usage
  • Operates at low voltages
  • Produces minimal heat
  • More longevity

LED neon was developed to have the same level of illumination while consuming much less power than regular neon.

How Much Electricity Do Neon Signs Use

There are three factors that determine the energy consumption of a neon sign: the type of sign, the size of the sign, and how long it operates per day.

Typical Power Usage

The following power usages have been observed:

Traditional neon lights: 3 to 6 watts per foot

LED neon lights: 1 to 2 watts per foot

LED neon lights are estimated to save 60 to 70 percent more energy than their glass counterparts.

What Does This Mean in Real Usage?

To make this easier to understand, let’s apply it to an example.

Think of a small LED neon sign for home or store use:

  • Sign size: 3 feet
  • Estimated power consumption: ~6 watts
  • Duration per day: 8 hours

Let’s now convert this into actual electricity costs.

Electricity Cost Calculation

As of early 2026, the average residential electricity rate in the U.S. is approximately 17.65 cents per kilowatt-hour (kWh).

A 6-watt sign running for 8 hours per day uses:

  • 0.048 kWh per day
  • Around 1.44 kWh per month

This results in a monthly cost of roughly $0.20 to $0.30 per month

What This Tells Us

Even with daily use, the cost of running an LED neon sign is extremely low. In most cases, it is comparable to or even less than charging a small electronic device.

For us, this is one of the biggest advantages of modern LED neon. It delivers strong visual impact without adding noticeable energy costs, making it a practical choice for both home decor and commercial use.

Will a Neon Sign Raise My Electric Bill?

This is one of the most common questions we get, and it makes sense. Anything that stays on for hours naturally raises concerns about energy usage. The short answer is no. A modern LED neon sign will not significantly increase your electricity bill.

To make this clearer, we like to compare it with everyday appliances people already use.

Power Consumption Comparison

Let’s compare the wattage consumption of an LED neon sign with other commonly used home appliances:

  • LED Neon Sign: 10 to 80 watts
  • LED Bulb: 2 to 18 watts
  • Laptop: 30 to 200 watts
  • TV: 30 to 200 watts
  • Air Conditioner: 1,000+ watts

An LED neon sign consumes very little power. Sometimes it is even equal to one LED bulb.

What This Means in Real Use

Even if you operate your neon light for 8-10 hours per day:

  • It uses less energy than your computer or television set
  • It is far more energy-efficient compared to other devices that use a lot of power, such as ACs.

Your energy bills will not be greatly affected by its operation. For most homes and small businesses, the cost difference is barely noticeable.

Our Perspective

LED neon signs created by CRAZY NEON® are designed with both energy efficiency and lighting in mind. Compared to other things that you have around the house and that consume energy, they consume relatively less energy.

This is precisely why neon signs prove to be far more energy efficient than most people would ever imagine.

Common Misconceptions About LED Neon Signs

Here are some of the myths about neon signs that are not true for modern LED signs.

Myth 1: Neon signs consume a lot of energy

Fact: LED neon signs are made to be energy-efficient.

Myth 2: Neon signs function by using gas

Fact: Electricity drives the light, and in traditional signs, gas only affects the colors.

Myth 3: Neon signs are out of date and inefficient

Fact: LED neon represents an innovative approach to signage, combining efficiency and longevity.

Myth 4: Neon signs become extremely hot when operating

Fact: LED neon signs remain cool to touch despite prolonged operation.

One can conclude that modern neon signs are much more advanced than many people realize.

Practical Tips to Reduce Energy Usage

Although neon signs are quite efficient, there are some basic tips that will help you make them even more effective.

1. Consider the Right Size

The bigger the sign is, the more power it consumes. Our recommendation is to choose the appropriate size.

2. Include a Dimmer

CRAZY NEON® offers dimmers that can regulate the brightness of the lights. The lower the brightness, the less power is consumed.

3. Schedule Operation Hours

Do not keep your neon sign operational 24/7. This practice will greatly affect the energy savings.

4. Consider Energy-Saving Builds

Our signs are built from UL-listed components. Thus, our products perform effectively and safely.

5. Installations

Neon signs installed indoors consume less power than those that are placed outdoors. They need less brightness.

6. Efficient Design

Complicated or very dense designs may require many LEDs. Try to keep your design simple.

Bonus: How to Control Your Neon Sign Power Usage

Managing energy usage becomes even easier with the right setup.

Indoor Neon Signs

  • Use dimmers to change the brightness depending on the time of day or mood.
  • Turn off when not in use.
  • Focus usage during evenings or key hours.

Outdoor Neon Signs

  • Use timers to automate operation.
  • Adjust brightness depending on visibility needs.
  • Make sure the installation is done correctly so that it works well in all kinds of weather.
