I recently bought the Niteye EC-R26, the price was good with a ~$11 discount this last Memorial Day.
I've been looking for a USB rechargeable 18650 light, this looked ideal. I was wrong, I've had nothing but problems with this light, some minor, some major.
Never had Niteye brand before and will NOT buy another. I have a JetBeam light (Parent company to Niteye?) I bought years ago (Jet-1 Pro IBS) I really like it.
I bought from another vendor some new 18650's. Both button top protected and flat top unprotected all were rated at 3400 mahr. I used these to test the new R26.
Not Happy with the R26
A couple things about the R26, I have serious doubts about the stated output on high & turbo. I have other lights rated at half the Lumen output that put out more light and are brighter.
>The light flickers visibly on all modes except the 2 lumen lowest mode.
>Sometimes the mode switch circuitry and switching gets messed up the light will stop working. Removing battery appears to reset everything and the light will work again.
>As a personal preference I do not light the switching arrangement. Two seconds for light to power of/off. This is not suited for any kind of self defense tactical use in my opinion. But this is ok as long as you understand that before you purchase.
>Both the on/off mode switch and the USB charging port are in the light's head on directly opposite sides. I find I have to hunt and rotate the light to find the on/off switch and often mistake them, pushing on the charger cover instead of the on/off mode switch. Again personal preference, I would prefer one or the other to be on the tail. This is one reason I prefer tailcap switches.
>Speaking of tailcap, removing the tailcap you have a spring simply pressed into place with a sorta Z shape what I would consider a poor mechanical (secures with 4 points of contact, not the entire circumference of a circular shaped spring contact) and electrical arrangement, I have no doubt at some future time I will lose this spring.
Pros:
I really like the low 2L level
This light is very compact, not much bigger than a single AA cell light.
The discounted Price was around $33
Final opinion after a few weeks of use, I would NOT recommend this light.
