Do Neon Signs Use a Lot of Electricity?

You’ve seen the glow. It’s bold, bright, and impossible to ignore—so it’s fair to wonder: do neon signs use a lot of electricity? The short answer: not with modern LED neon. Today’s LED neon signs deliver standout lighting with surprisingly low power consumption, making them a smart choice for homes, events, and businesses alike. At Yellowpop, our CertiLED™ technology takes that energy efficiency even further—keeping your sign cool to the touch, safe, and built to last up to 100,000+ hours.

In this guide, we’ll break down how much electricity a neon sign uses, the difference between traditional neon and LED neon, what affects power consumption, and how to estimate your costs per month and per year. You’ll leave with practical information to design a custom neon that looks incredible and runs efficiently.

 

Do neon signs use a lot of electricity? The quick answer 

No. Most LED neon signs draw roughly 20–120 watts depending on size and brightness. That typically translates to just a few dollars per month in electricity for home use—and modest costs for commercial signage even when you run it for many hours per day. Traditional neon signs (glass tubes filled with neon gas) consume more energy and require high-voltage transformers, while LED neon signs are lower voltage, safer, and far more energy-efficient.

 

Traditional neon vs. LED neon: what’s the difference? 

Both options create the iconic neon look, but the tech under the hood is very different—and so is the energy consumption of neon.

Traditional neon (glass + gas)

Classic neon lights use glass tubes filled with neon gas or argon, excited by a high-voltage transformer. They’re beautiful, but the glass tubes are fragile, the system runs hotter, and the sign will usually consume more power to maintain that glow. Maintenance can be higher, too, especially for larger signs or outdoor installs. This is one reason why our durable, weather-resistant outdoor neon signs use modern LED technology.

LED neon (what Yellowpop makes)

LED neon signs mimic the neon light style using flexible LED technology inside durable silicone tubing. They operate on low-voltage 12Vdc power supplies, run cool, and are highly energy-efficient. With Yellowpop’s CertiLED™, your sign keeps consistent brightness while converting only about 5% of energy into heat—maximizing efficiency and safety. The result: less electricity, less heat, and a long service life (100,000+ hours).

 

How much electricity does a neon sign use? 

Let’s look at typical LED neon wattages and what that means for your bill. Actual draw depends on size, LED density, color, brightness, and animations—but these ranges are a useful starting point:

• Small LED neon (for a bedroom or home office): ~20–40W;
• Medium LED neon (for a living room or café wall): ~40–80W;
• Large LED neon (storefront, or as an event backdrop for a party): ~80–120W+.

To estimate the cost to run your sign, use a simple formula:

Cost = (Watts ÷ 1000) × Hours per day × kWh rate × Days per month

Examples using a common electricity rate of $0.15 per kWh:

• 30W LED neon sign × 6 hours per day ≈ 0.03 kWh × 6 × $0.15 × 30 ≈ $0.81 per month;
• 60W LED sign × 6 hours per day ≈ 0.06 kWh × 6 × $0.15 × 30 ≈ $1.62 per month;
• 100W LED neon × 8 hours per day ≈ 0.1 kWh × 8 × $0.20 × 30 ≈ $4.80 per month.

Annualizing it helps you plan kWh per year. That same 60W sign at 6 hours a day uses about 131 kWh per year (0.06 × 6 × 365), which is still modest compared to many household appliances. In other words, a well-made LED neon sign can give you major visual impact without a lot of electricity.

What affects a sign’s power consumption? 

Not all signs use the same amount of power. These factors influence your energy consumption and costs:

• Size and LED length: More tubing means more watts per linear foot;
• Brightness setting: Higher brightness draws more power; dimming saves energy;
• Color and mode: Solid colors are typically efficient; RGB animations can consume slightly more;
• Driver/transformer efficiency: Quality power supplies reduce loss for better efficiency;
• Operating schedule: Fewer hours a day equals less power consumption and lower costs.

Yellowpop’s LED neon signs run on efficient 12Vdc drivers, and our CertiLED™ standard ensures optimal brightness with less energy. Add a dimmer for even greater energy savings and flexible lighting control.

 

LED neon vs. everyday devices: context matters 

It’s easy to assume neon signs use a lot of electricity because the glow looks dramatic. Compare the draw to common devices and you’ll see how little power an LED neon sign can use:

• Small LED neon sign (30–60W): Similar to a single incandescent bulb or bright desk lamp;
• Desktop computer (150–250W): Often higher than many signs use;
• Hair dryer (1,000–1,500W): Minutes of use equal hours of neon light time;
• Fluorescent lights (4 × 32W tubes): 128W total—often more than a medium LED sign.

Bottom line: the power consumption of LED neon lights is modest compared to many lights and appliances you already run every day.

 

How to lower your electricity costs even more 

You have multiple options to keep energy use low while getting the exact look you want:

• Use a dimmer: Reduce brightness to match ambient lighting and save power;
• Set a schedule: Add a timer or smart plug to turn the sign off automatically after hours;
• Choose the right size: Scale the design to your space to avoid unnecessary wattage;
• Be thoughtful with effects: Solid colors are efficient; use animations and RGB when the moment calls for it;
• Keep components clean: Good airflow around the driver/transformer helps maintain efficiency.
