A neon lamp is a type of gas discharge lamp containing neon gas at low pressure. When voltage is applied, the neon gas glows with a characteristic reddish-orange light. Unlike incandescent bulbs, neon lamps don't use a filament; instead, they rely on the excitation of neon atoms. They are often used for indicator lights, signs, and decorative purposes due to their distinct color and low energy consumption. Think of it like a mini lightning storm inside a glass tube, but way cooler and controlled. They're not typically used for general lighting because they're not super bright.
