My guess is that it could happen.
But carrying the light in a backpack with a slightly untwisted tailcap or body will 100% prevent that from happening.
Nice review. Thank You!!
To my very senitive eyes and my camera, yes.
You are never wrong with an HICRI emitter.
Nice review. Nice light
I have lost the confidence on Manker. Does the flashlight that I receive will be equal to this? It will the same quality?
OMG!
… a good listener few words…
Nice review…pity there is none NW choice.
Yes, if anybody at Manker is reading this I would also love to see neutral white tint.
It is
Great…, Thanks a lot wings400!
Nice, thanks!
E11 have cw and nw choice.</p>
Great pics!
Great review!
Sorry ,That is the engineering prototype for review. There is no such a kind of problem with the E11 on sale.
Looks a really food flashlight!
Thanks!
Is Ebay the only place its available to purchase in the UK?
Wow…30 bucks…looks like a no brainer 
Great review. Thanks
Damn need the neutral version + a group buy or gearbest stocking it
Really like this light, but can’t decide which one to get.
The Klarus Mi7 is also very interesting.
It is ratet at 330lm from nihm and the E11 settles at around 300lm - so there they are similar.
The Mi7 has a XP-L HI led, so it should have a little bit more reach.
