NiteCore is the only one without a forward switch and when pressing the switch your may change light output. I also has a recessed switch.

The Fenix TK20 is thicker than the other lights and has a bigger reflector.

Your can compare four of them here:

Thanks for the excellent pics!

Can you help me understand how the NiteCore switch works? I was under the impression the bezel assembly needed to be turned in order to access the different light levels.

Thanks

I can try, but I will explain it another way than it is usual explained:

Your have 3 positions: off, on-1 and on-2

With the bezel loose your are in off and the switch can be depressed to on-1 and on-2.
When bezel are tight your are in on-1 and the switch can be depressed to on-2.

off is full off, no standby current is used.
on-1 can be on or off, and a small standby current is used.

The following functions are usual done with tight bezel, but can also be done with loose bezel:
Turning on/off from on-1 is done with a short press to on-2.
Adjusting the level is done with a long press from on-1 to on-2.
Two fast pressed from on-1 to on-2 will select lowest level.
A fast and a slow press from on-1 to on-2 will select highest level.

No, it's all through the tailswitch. There is a video which shows how the NiteCore PD system works.

The D20 works essentially identical to the D10/EX10

Wow, the NiteCore seems overly complicated for a tactical light. I think I'd be better served with a more traditional switch.

Thanks

The D20 was never advertised as, or meant for a "tactical" light.

It's not as hard as it seems. It's essentially a single mode light, and you set that one mode. If you want to change that mode, it happens to be easily accessible.

I understand now. My mistake was assuming the D20 functioned like the NiteCore Defender Infinity series, and that is just not the case.

Any rumors of a 2xAA version in the NDI series on the horizon?
