How many amps do most 14500 flashlights pull?

600 lumens with a xpl-hi V3 or V2 would be around 1.5 amps. The Sanyo would handle this just fine lasting just a little longer than the Efest 650 (purple).
But any light with a higher current draw than 1.5a the Efest will start to dominate the higher you go. Lasting longer and having a higher discharge voltage (less voltage sag). The Efest is a great high current battery in the 14500 size.
If your light is using XP-G2 R5 led 600 lumen’s should be around 2600ma according to Djozz graph.
Crash-testing a XM-L2 and a XP-G2 on copper Sinkpads - #52 by djozz
Your light would benefit from the Efest, higher lumen’s and lasting longer.

I have a question re lumens vs amps for the different kinds of Cree LEDs.

So XP-L Hi V3 @ 1.5A ~600 lumens

Where can I find the data for others, like XM-L2 (let’s assume the usual I see in specs are XM-L2 U2) or for XP-L HD V6?
Are the approximate lumens to amps almost the same? (other than some LED emitters can be driven to higher currents)
