Re: NEOFAB Legion II, the powerful MC-E light &COMP with M1X, pic heavy!
Before the professional 3rd party review, there is some test result from myself.
Sample B.
Output:
2.9A(full distance)
Runtime with 3*Ultrafire unprotected 18650 cells:
2h4m.
With the built-in battery gauge, we can see how the cells work:
level6 (full)->level5 : About 35mins.
level5 (good)->level4: About 35mins.
level4 (fair)->level3: About 25mins.
level3 (low)->level2: About 15mins.
level2 (quite low)->Warning->level1->Auto OFF: 10mins.
When the light is OFF, you can still turn it on for emergency. At lower brightness level, the cells can still provide some energy. For example, when the light shut down at MAX level, turn it on, and switch to the lowest level (about 400mA), then use the gauge, the gauge level might be level 4 (fair).
But I recommend charging the cells when the gauge is at level 3.
