LED Tower Lighting: Why It’s the Modern Standard for Obstruction Lighting Compliance

In the final chapter of our educational series, we'll discuss the benefits of moving away from incandescent and Xenon lights for your towers.  If you'd like to watch the video, check it out here on our YouTube channel.

For decades, incandescent tower lights were the standard for aviation obstruction lighting. While effective for basic visibility, these systems were inefficient, fragile, and costly to maintain.

Xenon strobe lighting followed, offering longer life and improved efficiency. However, xenon systems still relied on flash-tube technology and continued to experience reliability issues, especially in harsh outdoor environments.

The transition to LED tower lighting systems revolutionized the industry. Today, LEDs are the preferred solution for telecom towers, broadcast towers, wind turbines, and utility structures requiring FAA and FCC compliance.

Why LED Technology Changed Everything
Unlike glass bulbs or flash tubes, LEDs are solid-state semiconductors with:
 
• No filaments
 
• No corrodible contacts
 
• No fragile internal components

This makes LED systems highly resistant to shock, vibration, and temperature extremes—conditions towers face year-round.

Structural Benefits: Smaller, Lighter, and Safer
One of the most overlooked advantages of LED obstruction lighting is its low-profile physical design.
Traditional incandescent and xenon lighting systems use large housings that increase the Effective Projected Area (EPA)—the surface exposed to wind loading. This adds stress to tower structures.
LED tower lights are compact and lightweight, reducing:
 
• Structural load
 
• Wind resistance
 
• Long-term fatigue on tower steel

This improves tower safety and lowers engineering concerns.

Proven Performance in High-RF Environments
Modern towers operate in dense radio frequency (RF) environments. Older lighting technologies were vulnerable to interference and premature failures.
LED tower lighting systems are engineered to perform reliably in high-RF conditions, making them ideal for today’s telecommunications infrastructure.

Key Benefits of LED Tower Lighting Systems
1. Extended Operational LifeLighting Type Average Lifespan
 - Incandescent = < 1 year
 - Xenon =  2–4 years
 - LED = 10+ years
Fewer replacements mean fewer tower climbs, lower labor costs, and reduced safety risk.

2. Up to 90% Energy Savings
With efficacy exceeding 300 lumens per watt, LED obstruction lighting can:
• Reduce electrical consumption by up to 90%
• Lower monthly utility bills
• Decrease lifetime operating costs
This also supports sustainability and carbon reduction initiatives.

3. Community-Friendly Light Control
Advanced LED optics provide precise beam control, allowing towers to:
• Remain visible to pilots
• Reduce glare in nearby neighborhoods
• Minimize light pollution in urban and suburban environments

4. Environmentally Responsible Design
LED systems:
• Generate fewer lifetime emissions
• Contain fewer hazardous materials
• Support avian protection by reducing disorienting light patterns
This aligns with modern environmental and regulatory standards.

The Bottom Line: LEDs Are the New Standard
LED tower lighting is not just a technology upgrade, it is a strategic investment in compliance, safety, and long-term cost control.
LED obstruction lighting is:
• Safer
• More energy efficient
• Structurally lighter
• RF-resilient
• Environmentally responsible
• Many have the latest IR capabilities for improved night safety.

For tower owners and operators, LED systems represent the future of aviation obstruction lighting.

In this installment of our YouTube video series review, we'll cover the actual costs of ensuring your tower is lit correctly. Tower lighting is a critical part of aviation safety and federal compliance, but the true cost of tower ownership extends far beyond the obvious price of the lights themselves. To illustrate this, let’s break down the real monthly cost of operating a 300-foot painted FAA medium-intensity A1 tower using a legacy incandescent lighting system. To keep the analysis practical and budget-friendly, all costs are expressed on a monthly basis, which reflects how most operators track operational spending. Hard Costs: The Direct, Visible Expenses These are the line items that appear on invoices and budgets. 1. Lighting System Reserve • System purchase & installation: $17,980 • Depreciation: 12 years • Monthly cost: $125 2. Tower Painting Reserve • 300 ft painted tower • Cost: $40 per linear foot • Paint life: 7 years • Monthly cost: $140 3. Repairs & Compliance Documentation • One repair per year: $1,900 (parts + tower climb) • FAA paint card inspection & documentation: $233 annually • Monthly cost: $178 4. Quarterly On-Site Inspections • Required for compliance • Monthly cost: $89 5. Electrical Power • Legacy incandescent system • Average commercial electricity rates • Monthly cost: $60 6. Compliance Monitoring & Data • Monitoring unit installed: $1,900 • Depreciated over 7 years • Monthly service fee: $30 • Secure data plan: $10 • Monthly cost: $72 Total Hard Costs: $667 per Month This equals $8,004 per year for a single medium-intensity painted tower. Soft Costs: The Hidden Operational Burden Soft costs don’t show up on invoices, but they consume time, staff, and internal resources: • Coordinating tower climbs and repairs • Managing vendor schedules and contracts • Procurement and logistics • Site access and safety coordination • Documentation and recordkeeping • Internal compliance management These administrative burdens quietly inflate the real cost of tower ownership. Risk Costs: The Unpredictable Financial Exposure Even well-managed towers face uncontrollable risks: • Inflation: Rising labor, parts, and energy costs • Compliance risk: Missed inspections or documentation gaps • Capital shocks: Sudden lighting system replacements • Catastrophic events: Storm damage, equipment failures, accidents These risks can rapidly exceed annual budgets and disrupt operations. The Bottom Line: Ownership Is More Expensive Than It Looks Hard costs alone average $8,000 per year for a single FAA A1 medium-intensity painted tower. Once soft costs and risk exposure are included, the true financial burden is significantly higher. There Is a Smarter Way There is another model that can reduce your tower lighting costs by up to 50% while eliminating risk, compliance stress, and operational complexity.

Ever wonder why some towers are painted red (or aviation orange) and others are not? Here is part 4 of our educational YouTube series that helps you learn all about it! Not all towers use lighting systems for daytime visibility. Towers marked with alternating bands of aviation orange and white are classified under FAA Style A marking. Instead of relying on lights, these structures depend on high-contrast paint to remain visible to aircraft during daylight hours. Maintaining this marking is not optional, it is a federal requirement. What the FAA Requires According to FAA Advisory Circular AC 70/7460-1: “Antenna structures requiring painting shall be cleaned or repainted as often as necessary to maintain good visibility.” To determine whether a tower remains compliant, owners must evaluate the paint condition using the FAA In-Service Aviation Orange Tolerance Chart. Why Paint Fails Over Time Environmental exposure gradually degrades tower paint: • UV radiation • Wind abrasion • Rain and weather extremes This causes fading, which reduces contrast and aviation visibility. Once faded beyond tolerance limits, the tower is no longer compliant and must be repainted or cleaned.

Effective as of September 11, 2020, the FAA requires Infrared Emitters (IR) for your LED obstruction lighting for newly constructed towers or circular updates. The FAA’s Advisory Circular (AC) spells out the specifications for IR and obstruction lighting equipment. The obstruction lighting rules were created in response to the Safety Risk Assessment of LEDs in Aircraft Operations with the FAA establishing IR specifications for LED based obstruction lights. Specifications are contained in Airport Engineering Brief 98 and Infrared Specifications for Aviation Obstruction Light Compatibility with Night Vision Goggles, published December 18, 2017. Military, emergency service, and other helicopter pilots are starting to use NVGs more frequently for increased safety and to amplify visible light. The illustrations below highlight the need for IR with your obstruction lighting.

Tower owners with FAA Style A marking, which includes painted towers with red obstruction lighting at night, should be aware that there are cost-saving options to consider when it comes to periodic painting required for compliance. Here at LumenServe ℠ , our Never Paint Your Tower A gain program eliminates the need to repaint your tower for obstruction lighting purposes. First, let us clarify some background information. Painting of the structure: FAA Style A towers are painted to ensure visibility for air navigation, with specific requirements for painting the structure. The most important requirement is that the paint must meet the FAA's Aviation Orange color standard, which is Federal Standard 595 color #17875 for white and color #12197 for aviation orange. Additionally, the number of bands required on the tower depends on its height. You can visit our website for helpful information on each FAA Tower Style. Cost of painting of the structure: When evaluating the cost of painting a structure, there are five primary cost drivers: Material cost of paint – Paint costs approximately $70 per gallon with each gallon covering roughly 400 sq. ft. Tower type – There are three primary tower types - Guyed, Self-Supported, or Monopole. Each tower type is unique and requires a different amount of labor to complete depending on total surface area and other factors. Height of tower – As one would expect, the height of the tower is directly proportional to the amount of labor required to do the painting. Tower location – Tower crews charge to mobilize to the site. The more difficult it is to get to the location, the more the tower crew will charge to get there. Tower crew labor cost – The labor cost to paint your tower is typically based on the hours of work required for the project. Typically, labor will range from $25 per tower foot to $80 per tower foot depending on tower type, height, and location. Annual paint test:
