I've had nothing but troubles with my cheapo one, and i've seen the same thing happen on others, where after about an hour the whole candle just melts and forms a mass of hard wax in the bottom of the lantern. Total pain in the bum. Oh and they are the proper UCO candles too that I was using.
Anyone else had the problems with them?
Think its something to do with the spring that pushes the candle up,
But i just dont have time now to try and resolve it and use a WW1 folding lantern reproduction that was recommended to us, which takes half a normal household candle or a trimmed down UCO one
