Well, Willie's got a new nickname now - the Lantern King! I have zero knowledge of these style of lanterns, I thought they were all junk and pretty useless for light output.
But I do have some knowledge of the pressurised petrol/kero lanterns such as the Aladdin - we had no mains power on the farm when I was a child, and all we had for light was Aladdin lanterns - and they were very good lanterns. But they don't stand much of a knock, or the mantle falls to pieces!
