A lighter is a portable device used to create a flame, typically used for lighting cigarettes, candles, or other combustible materials. Lighters use a fuel source, such as butane or propane, and a spark or ignition source, such as a flint or piezoelectric crystal, to create a flame.

Many types of lighters are available, including disposable lighters, refillable lighters, torch lighters, windproof lighters, and electric lighters. Disposable lighters are the most common type and are designed to be discarded after the fuel runs out, while refillable lighters can be refilled with fuel and used again. Torch lighters produce a hotter flame than traditional lighters and are often used for outdoor activities such as camping or welding. Windproof lighters are designed to work in windy conditions and are often used by outdoor enthusiasts. Electric lighters use a battery-powered heating element to create a flame and are often used as a more eco-friendly and sustainable alternative to disposable lighters.

It's crucial to use lighters safely and keep them away from children and flammable materials. Always follow the manufacturer's instructions for use and disposal.
