This is a replacement glass globe for the Campingaz Super Symphony gas lantern. The globe surrounds the mantle, protects the flame from wind and spreads the light evenly, and it is the part most often cracked when a lantern is dropped or knocked over in the car. Fitting a new globe gets your lantern working safely again without buying a whole new lantern. Remove the lantern head according to the lantern's instructions, swap the glass and refit. Only use it on the Super Symphony lantern it is made for, and never run a gas lantern with a cracked or missing globe.
