The Davey Safety Lamp was made in London by Humphry Davy. George Stephenson invented a similar lamp but Davys invention was safer due to it having a fine wire gauze that surrounded the flame. This enabled the light to pass through and reduced the risk of explosion by stopping the "firedamp" methane gas coming in contact with the flame.
