context_page_description: A Wells light was a large paraffin-fuelled blowlamp used for engineering work, particularly for illumination, in Victorian times. At a time before widespread electrical lighting, they were the most common form of high-powered portable illumination used for construction work, particularly railways, civil engineering, shipyards and ironworks.
context_section_description: As well as illumination, the Wells light was also used where a large portable blowlamp was required for heating. They were sometimes used for heating iron rivets, inserted red hot, during the assembly of structural ironwork. Although such rivets were normally heated in small portable coke braziers (which also used a cheaper fuel), the Wells light was favoured for some final assembly work at height, as the smaller lights were considered lighter and easier to lift into place high atop a bridge.
  Wells lights were also used in the erection and repair of large stationary steam engines. Typically this was for the shrink-fitting of components such as large crankpins in crankshafts or flywheels. The crankshaft web would be heated to expand it until the pin could be slid or gently hammered into place. On cooling, the pin would be securely held in place.
