Djozz’s test of the XP-G3 S5 is here: Cree XP-G3, testing a S5 3A emitter
In the first graph you can see the light output compared to a 219c 5000K which shows that the XP-G3 outputs more light for the same power.
However, you need to specify the conditions to make sure you get the right answer to your question.
For example, if you run them at the same current controlled setting on the same light there will be negligable difference in the battery consumption but they XP-G3 will output more light.
If you reduce the current to the XP-G3 so it matches the light output from the 219c then the XP-G3 will consume less power so the 219c will consume more battery.
If you set them up to be able to see objects at a specific distance, i don’t know.
