Hi. Few weeks ago was torn between the m150 and the m200. I couldn't decide so I ordered both. The tiny E3A was free to order. But I thought my father-in-law has a birthday, and such a tiny one is always a nice addition to a gift. So I ordered one. I shared the idea with my wife, she said it was great and she wants one too... so I ordered... and it won’t be my last one.
Thank mate! It’s a hard question, especially after only a few days of owning them. For a pure EDC I think the E3A is the best answer, I have one together with my keys - and keys are always with me.
But between m150 and m200 I’d say… both are equally good.
Size: m200 fits better in my palm, m150 fits a bit better in my pocket and my bag.
Weight: I can’t feel any significantly difference
Lumens: when using li-ion battery, the m150 is only a little bit weaker, but only a bit in my opinion.
Runtime: m200 wins when it comes to a single battery, m150 with it comes to the ease of replacement - takes every AA battery as well as 14500 li-ion and NiMH (like IKEA Ladda).
Magnet: M150 stick better, because it’s a bit lighter and shorter (placing it horizontally works better because of that).
I’m sure I will rotate both. I like to have a bit bigger flashlight like M200. But M150 can fit into my wife’s bag and she even won’t notice it, lol.
