Lighters: Convential vs jet-style

I recently purchased one of these lighters.



It is refillable with the same lighter fluid that ordinary lighters are filled with and the ignition system is a simple electric spark (identical to those found in conventional lighters)



However, the properties of the emitted flame are vastly different. A convential lighter emits a yellow-orange flame that is easily disturbed by wind-currents, provides a fairly significant amount of light and a relatively low heat.



The jet-style lighter emits a blue flame that is not disturbed by wind currents at all and retains its shape. The amount of light emitted is significantly lower, while the heat produced is significantly higher.



I can only deduce that the differences between the flames must be down to the size/placement/shape/number of nozzles.



Can anyone please explain to me, how it is that a flame with such vastly different properties can be produced from the same materials, by simply changing the shape/placement/size/number of nozzles?



Further can anyone explain to me, specifically, why the blue flame retains its shape, how much lower light output and higher heat output?



pics of lighter in operation to follow (if I can get my phone to play along)
