Sign Lighting: LED vs. Neon – Part 1- Pros & Cons

Aug 24, 2012 | Sign Products

The main common theme  between LED and Neon is that they are both  a source of light  for signs (and many other items), but that is about it where their similarities end. They both have their place in the sign world, and in this portion of our multi-part blog we will see the basic Pros and Cons of each.

We will give a brief description of each here and go into more depth of both  in future posts.

LED – Stands for Light Emitting Diode, which is basically a semiconductor that produces light. There are for more LED’s in everyday life than you may realize, such as car instrument clusters, watches, calculators, etc.

Pros to LED lighting for Signs:

  • Extermely long bulb life (100,000 + hours)
  • High light output with low voltage input
  • Very low maintenance
  • Extremely durable
  • Unlimited color options
  • Doesn’t use mercury or any other toxic chemicals to produce light
  • Low power consumption

Cons to LED lighting for Signs:

  • Up front costs invested in future proofing
  • Some are somewhat directional (focused beam)
  • As with anything, there are cheaper/less reliable brands
  • Some higher wattage LED’s run hot and need a heatsink

 

Example of a Neon lit SignNeon is a low pressure gas inside a glass tube with and electrode at each end of that tube. When high voltage is connected to the electrodes, it charges the gas to a point that it gives off light that can be seen.

Pros to Neon lighting for signs:

  • Wide operating ranges
  • Sometimes they don’t need a special power supply
  • Can run on AC or DC
  • Can be made into custom shapes
  • “Old school” look and feel cannot be duplicated

Cons to Neon lighting for signs:

  • They  output very  little light  for amount of power required
  • Limited colors available based on gas and glass color configurations
  • The glass tubes can be fragile
  • Generally only one color can be used at a time
  • Very high maintenance costs
  • One small crack and the entire piece is broken
