There is much confusion about the properties of real neon due to LED companies conflating it with LED flex, which they incorrectly describe as neon
This post will cover the lifespan of real neon, what affects its longevity and how to care for it
Real neon, when made and maintained well, is a long-term investment
Real Neon vs LED: What Lasts Longer?
A neon tube can keep glowing up to 20-25 years of frequent use if installed and kept correctly. LED flex, on the other hand, will last only 3-8 years.
The lifespan of a real neon tube depends more on the quality of the craftsmanship behind it. With an LED sign, it doesn't matter how well it is assembled, it will degrade just as rapidly as it always does.
Real neon doesn't "burn out" like traditional bulbs would - it fades or dims over a very long time.
If a neon sign stops working with no sign of breakage, it's almost always a problem with componentry other than the neon tubes themselves, such as the transformer. These parts are easy to replace and never warrant the construction of an entirely new sign, unlike with LEDs.
What Affects Neon Longevity
Quality of craftsmanship: If a neon tube is bent by an exprienced specialist, it will be shaped in such a way that it maintains as much structural integrity as possible. A strong bend will resist stress and strain where a weaker bend may shatter.
Transformer: A transformer must match the voltage requirements for the sign it is powering, otherwise it can drastically affect the lifespan of the tubes.
Usage: While a neon sign can be turned on for very extended periods of time, it is advisable to turn it off when it is not in use as this will increase its lifespan
How to Know When a Neon Light Is Nearing the End
Fading or dimming glow: All neon tubes will eventually fade after a couple decades of use
Discolouration: This is usually caused by an error while putting the tube under vaccuum. Impurities within the tube will degrade a neon section much quicker.
Flickering: This can also be caused by impurities within the tube as well as the electrodes breaking down.
Can Neon Be Repaired?
Yes - all real neon signs can be repaired.
Common solutions include rejoining and re-pumping or remaking broken neon tubes, joining new electrodes to tubes or replacing a faulty transformer.
A full replacement of a neon sign is almost never necessary as individual components can be swapped out or improved upon without needing to do the same to the sign as a whole.
Disposing of a neon sign that isn't functioning is a waste; there could still be a lot of life left in many of the components that you're just not seeing.
FAQs About Neon Light Lifespan
Can neon really last 15 years or more?
Yes - if it is well made and well cared for.
Is it worth repairing older neon?
Yes - it is always more cost-effective to repair a sign than to replace it.
Does turning neon on daily reduce its lifespan?
Yes, but not significantly. Neon tubes that are used daily can still last over 20 years.

Final Thoughts: Real Neon Is Built to Last
Real neon, unlike LED imitations, is a durable, serviceable and long-lasting lighting choice.
