Nitecore EC4 (2X18650/4XCR123A, XM-L2)

Nitecore EC4 is a compact and good heat transmission flashlight. Perhaps not impressive for some people, but for me, yes it is. Keep a flat lane for more than 950 lumenes for about 2 hours. Not time step down, thermal management… Is very confortable and lightweight, I have not sensations of 2x18650 flashlight in my hand.

Impressive runtime graph! Thanks for the review.

Yes is a really great regulation. For make the runtime graph I measured light intensity once per minute.
Thanks for comment.

Looks like a great reliable light.

Good Job. :wink:

The standard tripod thread is useful and is compatible with defensive elements like the SUNWAYMAN or JETBeam spike:

Nice review - thanks. These flat lights are surprisingly comfortable - I have a Jetbeam PA40 which is great in the hand.
