Nikola Tesla Mini Plasma Lamp

Inside the glass sphere, there is a mixture of gases, typically neon, argon, or xenon, at low pressure. When a high-frequency high-voltage electrical current is applied to the electrode at the center, it ionizes the gases, creating colorful streams of glowing plasma that move in response to touch or proximity.

Plasma balls can emit electromagnetic radiation, which might interfere with nearby electronic devices such as radios or computer screens. However, the interference is usually minimal and temporary.

Yes, plasma balls are generally safe to touch. The plasma filaments they produce are low-temperature and harmless. However, if the lamp is damaged and the glass shatters, please dispose of the product as touching the central electrode itself when the plasma ball is turned on can lead to electric shocks. As long as you're touching the glass surface or the plasma filaments, there should be no risk of harm.

Plasma balls are generally not considered highly energy-efficient compared to some other types of lighting, such as LED bulbs. While they don't consume a significant amount of electricity, they do require a continuous supply of power to maintain the plasma filaments and the glowing effect. Due to its small size, this lamp has low power consumption and operates on 5 volts.
