WebOct 5, 2024 · A neon light contains a tiny amount of neon gas under low pressure. Electricity provides energy to strip electrons away from neon atoms, ionizing them. Ions are attracted to terminals of the lamp, completing the electric circuit. Light is produced when neon atoms gain enough energy to become excited. WebDuring this process, light is created. In contrast, an incandescent light bulb works by passing electricity through a small wire, or filament. The electrical resistance of the filament causes it to get so hot that it glows, producing light. The fact that LED lights do not rely on heat to produce its light means it runs cooler and is much more ...
