Strangely enough I think this is slightly noisier in operation than the twin mantle version... At first I thought there might be an issue as it sounds slightly blow torchy but I've had it running for over six hours in one go without any problem so I assume that is just the way it is.
This leads me on to something I've wondered about for years. Just what was the point of a twin-mantle lantern? Yank oneupmanship?
I would assume more light output, but I wonder if they are also less flickery given that the two burners are unlikely to flicker in sync... If you think about it street lamps before the days of these horrid electric things often had four or five mantles.
Yes I rather like this series of lamps Jeff... As I'm sure you know they also did the larger 295 twin mantle version as well as Coleman fuel versions of all three.
