Obviously (matches the keyword "lamp" :-)) is that the supplied clay burner is a potential wear parts. Especially when the lamp also just want to heat, and therefore constantly changes the burner. And: The manufacturer states that you can get even additional 10-20% light output with the VA-burner.
I have by the way of all: According to Wikipedia Petroleum has an energy density of 9.5 kWh / L. If you believe the information, after which the lamp with a full tank of 1 L for about 8 hours burns (dimmable it is not really), one arrives at a power of 1.1 kW. If one believes even the manufacturer's specification of 400 W light output, are doing 700 W into heat. The bulb lights up longer, the ratio shifts in favor of the light output.
This is better than any energy saving bulb, LEDs themselves come there with difficulties, however, weigh none 3 kg without batteries. Thanks to Auer von Welsbach for the mantle. The VA-burner, the large reflector screen and the side reflector do then rest.
