Installing LED Sign Tubes: What You Need to Know

In a world where first impressions matter more than ever, your business signage can be the deciding factor in whether someone stops to check you out—or keeps walking. A bright, well-lit sign isn’t just a decorative element; it’s a silent salesperson working around the clock to draw attention. 

That’s where LED sign tubes step in. They’re energy-efficient, long-lasting, and designed to give your signage a clean, professional look day and night. According to the U.S.

Department of Energy, LEDs use at least 75% less energy than incandescent lighting and can last up to 25 times longer. That’s not just good for your electric bill—it’s good for business. 

If you’re considering making the switch or installing LED sign tubes for the first time, here’s everything you need to know to get it right. 

Why Businesses Are Switching to LED Sign Tubes 

Upgrading to LED sign tubes isn’t just a trend—it’s a smart investment. Here’s why more business owners are making the change:

• Lower Energy Costs: Swapping out older fluorescent tubes for LEDs can cut your lighting energy use by up to 60%, saving you money month after month. 

• Extended Lifespan: Many LED sign tubes last 50,000 hours or more, meaning fewer replacements and less downtime. 

• Reliable Brightness: LEDs maintain their brightness for most of their lifespan, so your sign won’t slowly fade into the background. 

• Eco-Friendly Design: With no mercury and a reduced carbon footprint, LEDs are better for the environment. 

• Low Maintenance: Fewer burnouts mean less time (and money) spent on repairs. 

Things to Consider Before You Install 

Good preparation is half the battle when it comes to installing LED sign tubes. Taking a little extra time before you start will save you headaches later. 

1. Measure Your Sign Cabinet Accurately 

Measure the internal length of your sign cabinet to ensure you’re ordering the correct tube size. A wrong fit can delay installation and cause uneven lighting. 

2. Check Your Power Setup 

Some LED sign tubes work with existing fluorescent ballasts (plug-and-play), while others require bypassing the ballast entirely for direct wiring. Knowing your current setup will help you buy the right type. 

3. Pick the Right Color Temperature 

For most commercial signs, 6500K (cool white) is ideal—it gives that crisp, daylight-bright look that makes lettering and logos pop. 

4. Go for Weather-Ready Models 

If your sign is outdoors, make sure your LED sign tubes are IP65-rated or higher to withstand rain, dust, and snow. 

How to Install LED Sign Tubes 

While the exact steps depend on your sign and tube type, here’s a simple overview: 

Step 1: Turn Off the Power 

Safety first—always cut off power before starting. If your sign is mounted high, follow OSHA ladder and safety guidelines. 

Step 2: Remove Old Tubes 

If you’re replacing fluorescent tubes, carefully take them out and dispose of them according to local regulations. Fluorescents contain mercury, so they require special handling. 

Step 3: Prepare the Wiring 

For plug-and-play tubes, make sure the ballast is compatible and in working condition. For direct-wire LEDs, follow the manufacturer’s wiring instructions to bypass the ballast. 

Step 4: Install the New Tubes 

Place the LED tubes into the sockets and lock them securely in place. For double-sided signs, ensure even placement for consistent lighting on both sides. 

Step 5: Test Your Sign 

Turn the power back on and check for any dim spots or flickering. If something looks off, double-check connections. 

Step 6: Seal the Sign Cabinet 

For outdoor signs, make sure all seals and gaskets are secure to keep moisture and dirt out. 

Keeping Your LED Sign Tubes in Top Shape 

LED sign tubes are low maintenance, but a little care can help them last even longer: 

• Clean the Sign Face: Dust and grime can reduce brightness. Wipe down surfaces regularly. 

• Check Connections: Loose wiring can cause flickering or failure—inspect occasionally. 

• Watch for Dimming: If brightness drops significantly, it might be time for a replacement. 

• Maintain Ventilation: Overheating shortens LED lifespan, so ensure your sign has proper airflow. 

Why Bright Signs Matter for Your Business 

A dim or outdated sign can send the wrong message. In fact, research shows that 68% of consumers believe a business’s signage reflects the quality of its products or services. Another survey found that 76% of people have entered a store simply because its sign caught their eye. 

Bright, clear signage isn’t just for looks—it directly influences customer behavior and sales. 

Is It Worth the Investment? 

While LED sign tubes cost more upfront than fluorescent tubes, the savings on energy and maintenance quickly balance things out. Most businesses see a return on investment within 1–2 years, depending on operating hours and local electricity rates. 

You’re not just saving money—you’re making your business more visible and appealing to potential customers.
