Rexlight REX2.1 Cree XR-E - Mini Review - UPDATE: Received new REX2.1 Impressive...

[whc]

UPDATE 8/3-07: After finding the first REX2.1 I received was a defective ond and was not living up to the specifications provided, Kai at Kaidomain.com send me a new one that just received today (very good service) and let me just say WOW . So not it is time to update the review now when I have received a fully working REX2.1. Did not have time to edit the pictures I took, so the new pictures does not contain any writings on them.

For all of you who are holding back of getting one as a result of the bad output of the first one I got, I can now say that Kai @ Kaidomain will be QC every REX2.1 before shipping, so new buyers should not be worried of getting a defective one, it was as far as I can tell rexlight that faild on QC thir products.

Now to the review, anjoy .

Just received the brand new Rexlight REX2.1 (updated version of REX2.0). Got it directly from Kai @ Kaidomain, you can also buy it at Lighthound: http://www.lighthound.com/index.asp?PageAction=VIEWPROD&ProdID=2893

This review will focusing on what is new in the REX2.1 compared to REX2.0. If you want more details on REX2.0 I can point you to this review: http://www.candlepowerforums.com/vb/showthread.php?t=161789&highlight=rexlight

Updates in REX2.1 compared to REX2.0:
New UI (User Interface) with only 2sec memory function, plus tree new light modes (Daily/Tactic/Advance), I have made a video of the UI in action here: http://www.youtube.com/watch?v=0ZrazfJRGSM
The glass lens I thicker and has a better AR-Coating.
New LED&Reflector module (kind of a drop in module).
More soft rubber on/off switch cover makes it easier to turn it on/off.
Reflector is more textured, makes a not quite as good beam as REX2.0 IMO.
The PWM is now completely Flicker-free on low (I can't notice any flicker with my bare eye).
Only one o-ring in each end = easier to change battery compared to REX2.0.
LED/PCB now glued to the heatsink.
Low battery warning on Li-Ion (works very well).

That was all I could think of right now, here is what I find good and bad:

The bad - <-Updated!
- "Only" one o-ring in each end (REX2.0 had two).
- New reflector has noticeable dark halo surrounding the hotspot (the old REX2.0 was much better).
- The new switch rubber cover, makes it harder to make the flashlight stand on its tail (better on the new one I got).

The good + <-Updated!
+ Very bright, brightest one I got.
+ Switch much easier to press with new rubber cover.
+ Lens is thicker and much better AR-coating.
+ The UI is MUCH better than the REX2.0, like the "blink" when a mode has bean on for longer than 2 sec (indicating that the mode will be used next time turned on).
+ Like the new LED&Reflector module, like a drop in (reflector is tighten to the LED module).
+ The one o-ring makes it much easier to change battery.
+ Flicker free, no noticeable flicker detected with the bare eye on low.
+ Low battery indicator on Li-Ion (blinks when battery is low).
+ Good looking HAIII.

Now to some pictures for you to enjoy .

Left: NEW REX2.1, Right: OLD REX2.1 <-Updated!

The REX2.0 is NOT the original PCB/LED, my LED burned, so changed the whole PCB/LED module.

Re: Rexlight REX2.1 Cree XR-E - Mini Review - Comparing to REX2.0

whc,

Thanks so much for such a detailed and professional review. You put a lot of time into that!

The only thing I didn't see, and forgive me if I missed this somewhere, is Lux readings on the 2.1 on a 14500 on high.

Thanks again for your terrific work. :thumbsup:

Was a little error on the lux readings, corrected ...

It is very bright on 14500, brighter than REX2.0, but on Ni-Mh it is just awful.

Re: Rexlight REX2.1 Cree XR-E - Mini Review - Comparing to REX2.0

Kai knew that you were going to be the intial, in depth review. To not inspect your sample prior to shipping, is a FUBABelief.

I'll hold off, until the upgrades for the 2.0 come out.

Re: Rexlight REX2.1 Cree XR-E - Mini Review - Comparing to REX2.0

Wow, nice review. Very well done. However, I wish you were talking on your video to help walk through the UI. Anyway, Thanks!

Well, I must say I am impressed and disappointed at the same time. Can't say for sure yet as to which way I am leaning.

The good for me:
- New UI (I love that it starts out in LOW)
- Low battery warning on Lith-ions
- 2 sec. memory
- Flicker-free PWM
- A very low, low (even on Lith-ion)... NICE!!!!

The bad for me:
- It appears that it is brighter with a Lith-ion than the Rex 2.0, but still not even as bright as the L1D-CE. This was supposed to be brighter than the L1D-CE!
- Dark Halo??? I believe the reflector is too stippled for me. I prefer the Rex 2.0 reflector. I really like the lens though.
- HAIII has a slight, but very noticable mismatch.
- Can't even tail stand with GITD tailcap? Come on now.
- Not liking that it is a tad bigger than the Rex 2.0...
- The lows look a little blue to me, maybe it is just the pics.... or me.

I wonder if buying the Rex 2.0 and then getting the upgrade module is the way to go...

Oh, how is the heat while running a 14500?

Depends on how you look at it. The L1D was not made to run on li-ion and has only one level of light with one. The Rex has all of it's levels. The L1D is only about 15lms brighter, not much.

Yes both bad and good news, it will not replace my L1D-CE ad EDC, was hoping it would, like the Rexlight looks/feel/size better than L1D, but for now it not quite makes it for me.

The flashlight gets hot on Li-Ion 14500, but not too hot to hold in hand. Am in the middle of a runtime on 14500 protected 1 hour 10 minutes and counting, not bad.

I am looking at it the only way I can; brightness. The Rex 2.1 was supposed to be brighter on a 14500 than an L1D-CE. See Kais' post here showing the graph:
http://www.cpfmarketplace.com/mp/showpost.php?p=2034949&postcount=2

And his response here:
http://www.cpfmarketplace.com/mp/showpost.php?p=2036397&postcount=66

See the brightness comparison between Fenix L1D CE and REX2.1. MKIIx stands no chance...

The JetBeam MKIIx that I've seen are even brighter than the L1D-CE, so with Kai's comments, I was thinking that the Rex 2.1 should at least be brighter then the L1D-CE.

Also:

On freshly charged 3.7V Li-Ion 14500 - all the brightness levels (low, medium, high and Turbo) appear to be the same. When the battery's voltage drops then the levels are differentiated - however that also means the battery is near the end of its capacity.

Re: Rexlight REX2.1 Cree XR-E - Mini Review - Comparing to REX2.0

The reflector/LED/driver sandwich does look quite different to the rex2.0 ... how will the upgrade module fit in the old rex?

 

[jsr]

Re: Rexlight REX2.1 Cree XR-E - Mini Review - Comparing to REX2.0

whc - great review! Thanks very much! Would you be able to take any output measurements on alkaline AAs? That's what I plan to use and am wondering if the extra voltage from alkalines would help the output somewhat. Runtime comparison with alkaline between the 2.1 and 2.0 would also be very greatly appreciated! Thanks.

Re: Rexlight REX2.1 Cree XR-E - Mini Review - Comparing to REX2.0

As far as I kan understand, the new upgrade will be included LED module, Reflector, and Lens. The internal dia. is the same on both, so should fit without a problem.

Re: Rexlight REX2.1 Cree XR-E - Mini Review - Comparing to REX2.0

whc - thank you for an incredible in depth review. It does appear though that the 2.0 is still brigher even with the Li-Ion on high. It also seems that Kai is again missing the mark on a number of claims about this light.

The hotspot of REX2.1 is not as strong as REX2.0 (more floody, and not as good quality wise as REX2.0), I think that it makes it appear les bright than it actually is, the lux readings is over 2000 lux more for the REX2.1 on 14500, so overall more light is defiantly coming from the REX2.1.

The new reflector is not good at all IMO, like the old one better, to bad they changed this, because it was as perfect as it could get on REX2.0 .

Wee found some Memorex, though don't see Alkaline written on them, see Zink if that is some battery tecnology???

See this image:

Will they do?

Re: Rexlight REX2.1 Cree XR-E - Mini Review - Comparing to REX2.0

That's carbon Zinc, heavy duty.

Much weaker than alkaline.

So is this the order you like?

1. Fenix L1D
2. Rex 2.0
3. Rex 2.1

?

Ok, will se if I can remember to get some good alkaline's tomorrow then ...

If I had to make a list it would be like this:

1. Fenix L1D-CE (har to beat, very good on Ni-Mh)
2. Rexlight REX2.1/2.0 (both have issues I don't like)
3. Amilite T5 (Bright, but poor runtime on Li-Ion)
4. Lumapower M3 (To big and bulky, but good quality beam)
5. Dexlight X.1. (don't have one anymore, but it is just to advanced)
