I'm not surprised. The evaporation of the gas has a cooling effect and the cylinder needs to be able to absorb heat effectively enough to counter that.
We use Camping Gaz, originally in C206 cartridges later the CV resealing variety for a lamp in the tent and, now, in the caravan awning. The C206 and smaller CV cylinders, even in moderate temperatures - evening in S of France but at altitude -, cool to the point that the light looses brightness. The bigger CV470 cylinders cope better.
