Noble gases are special and often used in lighting because they have some unique features. But there are challenges we face when using them:

• Inert Nature: Noble gases don’t react much with other things. This makes it hard to create light using less energy.
• Cost: Some noble gases, like xenon, can be really expensive. This makes it difficult to use them everywhere.

Luckily, new lighting technology is helping to solve these problems. For example, we can look for other ways to create light, like using more efficient LED lights. These LEDs can mimic the effects of noble gases without the same problems.
