This lantern burns orange with 4 or 5% O2 and less than 10ppm CO in the stack, or with extra air, the flame turns blueish and shortens (premixed) with 8% O2 and 100ppm CO. It lasts around 3 hours on wood pellets.

The "blue" movies don't show up well. Only where the flame has greatest density does the camera pick it up. There is actually a lot more blue "vapour" than it shows.
One is taken burning smokey wood gas the other is burning CO at the end when the burner becomes an updraft charcoal gasifier.
