Prometheus electronic piezo lighters have a built-in electronic piezo unit inside of the lighter. When the ignition button of the electronic piezo lighter is pushed down, butane gas is released from the gas tank and at the same time, an electronic spark is generated. When butane gas and electronic spark come in contact, flame is generated. The turning of the spark wheel of flint lighters could be hard on your thumb. The electronic piezo lighters have been the choice of smokers who do not like turning the spark wheel of flint lighters and who prefer visible soft flame to invisible, strong jet turbo flame.
