Is this P7 I or J bin 3,36volt =1,48 amp 3,54volt =2,23amp

Is this P7 I or J bin ??
3,36volt =1,48 amp
3,54volt =2,23amp

Volt measured under load
Power source= 18650
Volt resting 3,80 under load 3,36
Volt resting 4,10 under load 3,54

Using the same 18650`s
A MC-E should be a k in a C-2 direct driven
volt 3,1=2,4amp (volt resting 3,80)
volt ?? =3,36amp (volt resting 4,10) didnt want to risk the LED measuring the volts

As it seams i cant use this P7 and getting fullpower from my 18650 even direct driven

But using the MC-E i for sure need a driver

The 18650 with the resting voltage of 3,80 is giving me 3,1volt X 2,4amp =7,44 WAT

With the P7 the same 18650 gives me 3,36volt X1,48amp =4,9728 WAT not good for a single 18650 flashlight
