Review: Nitecore EX11.2

What an awesome looking light. I can't wait to get mine, and hope it's not a lemon (yes I know it's more likely on these lights!)

It will, but only for a short while if on RCRs. The driver unfortunately stays in DD mode for quite a while, and you don't see a regulated output with RCRs, instead you will get a pocket rocket.

Ive had mine for a while, and what I would recommend is making a new spring for the driver pill. I still find the switching a tad too hard for my liking, but with a lighter spring, the switching force can be lightened and brought closer to the feel of the good old D10s. Its not easy, but its a UI improvement I feel it needs to make multiple clicks and ramping easier on the hands.

totally agree here, but my hand gets a nice workout, or thumb anyway. Someone sell that spring?

nice review, thanks!

I just made my spring from some SS wire I had around. Wound it around a screwdriver, and with some careful tweaking to get it as close to round as possible, it works fine. In the EX11, its easier to get it to work smoothly compared to the D11, because the inside of the EX11 is smooth, as opposed to threaded in the D11. It does require some careful work, and I probably spent an your casually making this spring, but its worth it.

I dont recall what SS wire i used, but it was probably 0.8 or 0.9mm wire.

Mine arrived today and I really like it. I agree the spring resistance makes the button hard to press and slightly less resistance would be nice, but it's ok by me how it is.

After reading a bit I see there are different v2 versions floating around, and I ended up with a "Smart PD EX11 SP R5" with "V2" stamped on the opposite side. I was surprised to get one with a slotted piston, which is both good and bad in my opinion, because now I have to go and spend time figuring out how to do the GITD epoxy mod :).

I'm leaving the battery in to see if it's a battery vampire which is supposedly fixed now...we'll see!

You mean tritium vials ;)

Very cool...thanks :)

Dont do it... tritium vials, at $7-11 each, seem relatively affordable at first, but once you get started.....

(btw, I used B@rts trits, his are $7 for the 1.55x5 and $11 for the 2x8mm, you need a 2x8mm trit in your EX11.2)

BTW, don't expect anything bright, they are about as bright as cheap DX GITD tail caps after a minute of fade out or so. But the difference is it doesn't need charging, and its glowing when you need it!!... unlike GITD that only glows after you have activated it, i.e. you already have the torch.

My EX11.2 ramps smooth on CR123a but on 16340 the ramping is jumpy... anyone else notice that, or am I just special? :)

Not sure about yours, but mine has a single jump somewhere about 10-20% brightness (halfway during the ramp)

I also do see a stepped ramping, as if the brightness ramp involved 100+ steps. The original EX10/D10 had a more visibly stepped ramp (50 steps?) but the later EX10/D10s had a ramp with more steps that could not be visibly discerned. The current EX11.2 has steps that are somewhat in-between, smooth, but visible if you tried to look for it.

Thanks. I watched it more carefully and on 16340 it does do what you describe. I'm glad it's normal!

WHAT may I ask are u using for your 16340? Thanks...

I'm using unprotected trustfire flames from DX.

Unprotected is pretty scary on this driver, because it runs fully regulated down to 1.7v, and can provide light under 1v. Means you can run batteries dead dead flat before you even realise. Not a problem with vigilant battery management, however I know I can't be trusted... ;)

I also finally got a tritium picture which doesn't look excessively bright... The room was practically pitch dark though, this is probably still a tad brighter than what you will see. The camera can see the blues pretty well and it seems as bright, but to the human eye, blue is almost not visible, green is many times brighter, and yellow is in-between.

I'm super vigilant with them along with my unprotected 18650s, and tend to top them off far more often than needed. I've actually never had one go below 3.7v so far.


Awesome picture by the way!!

If I wanted to a machine shop to mill me a slot in a piston for an ex10/11, what size should I tell them to make it?

the size depends on the size of what you intend on putting into it. The ones I did were just manually milled and was a trial and error thing to get the tightest fit for the glass vials I had. You can get various sizes and its best to find dimensions to fit what you have.

The vials I've used have have been in 3 sizes, 1.55x5mm, 1.5x6mm, 2x8mm. Remember to account for the radius of the mill, in other words, the rounded edges of the slot. I haven't measured the slot, but I'm Guessing... 0.3-0.6mm larger in dimensions as bare minimums

Thanks, the 2x8 mm ones seem to be readily available on CPF. I'll see if my guy thinks he can do it with out screwing it up!

I Love the tritium arrangement in your Nitecore D10 grey! I don't know why I haven't seen anyone else with that. Are they 1.55x5mm vials in that one?
