I haven't heard of the issue with any cool whites, so just wondering.
It's quite neutral looking for a cool though.
Heh, my neutral is quite cool for a neutral. Coolest neutral I own. Still okay, but I'm a fan of warm white, so I would have preferred it about 500K-1000K warmer.
Just playing with it now, when i turn off from moonlight, it kind of fades out over about 1 second, but definitely goes out completely, held right up to my eyeball.
Yes, that's normal. It takes a few seconds for the LED to cool off and stop emitting any light.
Does yours still stay lit even when you lock it out (hold both buttons for few seconds)?
No, it doesn't. However, that may be a result of the brief turbo flashes the light does before going into lock-out mode. It's a bit like turning it off from turbo, which I almost never get a "sub-moonlight" from.
Only problem I have had with it is occasionally the red battery indicator led doesn't come on when batts are getting low. It still steps down through the modes as batts run out though, just no red light. This has happened probably 3 or 4 times in the dozens of times I have run through a set of batts.
Yes, you won't get a warning unless you have your light on at least medium mode, high is better. The reason is because they set the warning threshold too low for a low-current use. The warnings are set at 3.6v and 3.2v. That's only 0.9v and 0.8v per cell. Eneloops at that resting voltage level are completely dead. So, if your light isn't using much current (it's on low), the batteries will die before the red warning is trigger.
It works better if your light is on high, because then you have voltage sag from the high current. So, the Eneloops will get down to 0.9v or 0.8v under a high load, before they are completely drained. Then you get the warning flashes. I find you don't get much warning, maybe 30 seconds, but you get some.
I think I'd rather they set the voltage threshold a little higher. Perhaps 4.0v (1.0v per cell). It can't be too high, because then you'd get a warning every time you ran the light in turbo.
