FAA Tower Lighting Configurations
Red lighting/paint is an option for any height
tower for daytime marking.
Medium Intensity white lighting may be used in
lieu of paint on structures up to 500’ tall.
High Intensity white lighting may be used in lieu
of paint on structures over 500’ tall.

Light Sources
• What are the options & what’s the best?
-

Incandescent
Strobe
LED
Incandescent Light Sources
Advantages :
Lowest “up front cost”
Numerous distribution sources
Fairly resilient to lightning
Plug and play to most broadcast towers
Disadvantage :
Short lamp life, high “reoccurring costs”
Frequent maintenance
Susceptible to vibration damage
Extremely inefficient, Consumes lots of power
Light Pollution, ground effects!
Strobe / Xenon gas Light Sources
Advantages :
-Longer life technology than incandescent.
-Efficient power consumption
-Numerous distribution sources
Disadvantage :
-Large “upfront” costs
-Proprietary replacement technology
-New electrical infrastructure
-Limited lamp life, depending on design
-EMI / RF issues and ozone release
-Expensive High Voltage replacement components
-Expensive maintenance costs
- Light Pollution, ground effects!
Light Emitting Diodes!
• LED obstruction lighting
– Advantages
• Lowest cost of ownership
• Plug and play with existing infrastructure, 120VAC
• Solid State, extremely robust ad reliable, impervious to
shock/vibration.
• Extremely energy efficient power consumption. 48 Watt beacon
• Precision optics. Warranted performance!
• No EMI created or susceptibility
• Not prone to damage from surge/lighting.
• Numerous distribution sources
– Disadvantages
• Reputable manufacturer with extreme knowledge of LED based
products is a must!
LED’s (Light emitting diodes)
Development timeline
-60’s & 70’s calculators and watches
-80’s: Interior uses such as panels, PC’s
-90’s: Traffic Intersections & Brake lights
-2000 Obstruction, railroad, aircraft,
-2005 - UL, Class 1 Div 2 area white lighting
-Today and beyond: General illumination!
Making the transition…..
• Going from a light bulb to a light engine
– Generally, a single LED cannot replace a single light
bulb
• A “Light Engine” is required

Concerns and Challenges: Defining End of Life?
• What is the difference between the end of
life of an LED and that of a halogen or
incandescent lamp?
– Incandescent/Halogen is
catastrophic…whereas a LED light
output degrades
• The question one should ask is:
– What is the USEFUL LIFE or
EFFECTIVE LIFE of an LED fixture?
• Completely dependent on many
variables
Ultimate Solution: Responsible Designs
and Manufacturer Warranties
Manufacturers must take the lead to
ensure that their products meet the
minimum operational and intensity
requirements at the end of the
product’s warranty period!
A side note….controller and
monitoring systems
• Dialight DOES NOT manufacture controllers or
produce lighting “systems” as our focus is on LED
technology.
– We focus on upgrading / retrofitting existing lighting
systems to LED based fixtures
– Installing new LED fixtures with the partnerships with the
industry OEM’s.
• Please contact the vendor of your choice or visit our website for a
list of our existing distributors and OEM partners.
Minimum Maintenance Procedures
• All technologies
– Clean exterior optical portions of fixture
– Inspect and verify controller failure modes by creating a fault
– Inspect conduit & wiring for degraded connections
• Incandescent
– Ensure minimum of 120 VAC at lamp
– Inspect Gaskets & Seals around Fresnel lenses
• Strobe Tube
– Inspect high voltage controller capacitors and trigger cards
– Inspect fixture wiring and terminals for corrosion (Ozone)
– Re-lamp tubes per manufactures warranty (2-3 years)
• LED
– Re-lamp and install new gasket every 10-12 years
– Ensure 85 VAC at lamp
