How do neons emit light?

Neon lights work by passing an electric current through a gas, typically neon, to create a glowing light. When the electric current passes through the gas, it excites the gas atoms, causing them to release energy in the form of light.

What is the environmental impact of neon signs?

Neon Lights 

Neon gas, like all noble gases, is chemically inert and does not react with other substances in the environment. Buyers can choose energy-efficient options such as LED neon lights, which use less energy and last longer than traditional neon lights. 

For example, we use LED Flex, which is free from hazardous gases and mercury.

What is the durability and maintenance of neon lights?

Neon lights are relatively durable and can last for many years with proper maintenance. LED lights have a longer lifespan than traditional neon signs, but regular maintenance is essential to ensure the longevity of neon lights.
