There is a number of flashlights that claim upwards of 900 lumens from a Seoul P7 flashlight, using a single R-18650.
Please don't cite examples, we all know they exist.
I'd like to get such a light. However, I have doubts as to whether one R-18650 can provide the oomph necessary to produce that sort of output. And if it could, would the switch and steel spring wires be able to handle it?
I'm just looking for a reality check here. I know the P7 can be wired different ways, and have different drivers. But I seem to remember from my school days that the watts to the emitter cannot be greater than the watts from the power source.
Let's say a P7 light is fed with one R-18650. What is the maximum lumen output possible?
What if 2 RCR-123's were used instead? Any closer to 900 lumens?
TIA
