Review: Yezl Z1X XM-L

Yezl Z1X XM-L

Reviewer's Overall Rating: ★★★☆☆

 

Summary:

Battery: 1x 18650 li-ion
Switch: reverse clicky tailcap
Modes: 3 Hi-Med-Low
LED Type: Cree XM-L T6
Lens: Glass
Tailstands: Yes
Price Payed: $29.99
From:cnqualitygoods.com
Date Ordered: 2-25-2011

 

Pros:

  • Small form factor
  • Very very bright
  • Disassembles easily
  • Nice design and decent components

Cons:

  • Average construction (assembly)
  • Tailstands wobbly if lanyard is attached
  • Very ringy beam
  • Dropped once and needed repairs (see below)

Features / Value: ★★★☆☆

This is kind of a departure for me to review a torch I haven't built or modded, so bear with me.  I'll try and keep it short and to the point:

The Yetzl Z1X is a small, lightweight torch offering the latest cree emitter, the XM-L T-6. It combines an extremely high output in a form factor much smaller than the typical P60-style affair.  Modes include a Hi, Med, and a Low with no strobe or SOS. GITD o-rings are used throughout including the tailcap.  A glass lens comes stock, although I doubt it's AR coated.  

 

Design / Build Quality: ★★★☆☆

Here's the part were I got impressed and ticked off at the same. The design was very well thought out, with quality materials used and attention to issues a torch like this may have as an EDC.  As you can see above, the torch disassembles relatively painlessly and allows access to the pill, switch, and refector without a lot of work and/or swearing.  The threading is so-so... better than the x2000, but not in the same league as a fenix or zebralight for smoothness (even after lube). The pill is a quite thick and solid affair...more so than any other budget light I own.  The emitter was also secured in place via thermal glue, and not just held down by a plastic ring like a lot of other lights.  This makes me feel better about running it in high mode for somewhat extended periods (I'll get to that in a minute).  With a spring on the base of the driver, flat top cells are usable, and both protected and un-protected cells fit just fine.  

  The bad news came not from design, but implementation.  The threads were dry, minimal grease on the O-rings, and it quit functioning after one tumble out of my pocket.  Now these are all easily remedied with oil, silicon grease, and a bit of solder...but I don't feel this should be necessary for a torch costing $30. The reason it stopped working was because the driver board lost negative contact.  

In the above picture you can see the base of the pill and the brass retaining ring that sits on top of the driver board and holds it in place while providing a negative connection.  The problem here is that the small fall caused the ring to unseat a bit and lose connection with the board.  A small dab of solder fixed this from happening again, but I feel it shouldn't have happened in the first place.  I thought the ring at first was a nice touch, but now I only see it as a failure point.  A few solder joints around the edge would not only hold the driver in place better, but provide a solid electrical connection to ground and prevent it from failing from a minor bump.

I also need to mention the minor "attack crown" bezel.  It is stainless, not all that sharp, and purely for decoration.  That's right, it can be removed and the lens will stay in place, so if you don't like it just take it off ( Or send it to Boaz, he's good at grinding them down Wink)

 

Battery Life: ★★★☆☆

Sorry folks, I honestly don't have the patience to do a rundown test.  What I can do though is give you the tailcap amp readings to give you an idea of battery life.

Low:310ma

Med:940ma

High: 3.3amps!

Well now, they kind of overshot their specs of 125ma, 840ma, and 2.5a.  Like most stock modes, my only complaint is the low mode, which is over twice what was stated.  I think @100ma or less would be ideal.  Then again I like really low low modes as well... Much like death and taxes though, I've come to accept this from most budget torches.

A note on heat:  As you can imagine, the torch heats up rather quickly on high mode.  I take this to be a good thing because it tells me the heat is getting out from around the pill (I did add thermal grease to the pill upon reassembly). Although, it will also limit how long one can run it on high mode.  Crazy output in exchange for heat....not necessarily a bad thing, just something to keep in mind. 

 

Light Output: ★★★☆☆

As you've probably expected from the current draw, this torch puts out an amazing amount of light for such a small package.  The tint is similar to most of the other xml's I have in that it leans toward neutral, and is quite pleasant.  Again, I wish low was lower because in output medium and low are too close together.  My biggest gripe here is the ringy beam.  I wouldn't have thought it a problem with the large xml, but I'm here to say this is one seriously ringy beam.  I can even notice it in use outdoors. Here's a shot:

The garage door doesn't do those saturn-esque rings justice.  This is something I won't live with and will take it apart and use a misting of clearcoat on the reflector. Now let's take a look at some beamshots as compared to the zebra SC60 and the infamous MF drop-in:

Control shot:

Zebralight SC60:

 

MF xml drop-in:

Yezl Z1X xml:

As you can see, in overall output the Yezl compares quite favorably with the MF drop-in.  The differences are purely due to reflector, as the MF xml throws a fair bit better. 

Edit:  Lux readings @1meter = 7.4k lux on high

            Lumen output on high = 814.2L

 

Summary: ★★★☆☆

I've been carrying this torch for about a week now, and I do like it.  As you can see from the stars, I rate it smack dab in the middle due to the good being offset by the bad.  Then again, I haven't had or seen a torch yet I'd rate a 5 star, so maybe I just have high expectations.

  I purchased it because I was intrigued by the light output in such a small form factor, and thought it was a good looking light. My review may come across negative, but that's just my way of ensuring that the excitement of a new toy doesn't taint my viewpoint and that the pro's and con's are covered accurately.  

Bottom line, yes...I'm happy with my purchase and I think it's a fine torch.  There are no show-stoppers here with the negatives and with a little bit of tinkering can make it even better, and I find myself reaching for this torch now over some of my others. It's the only other 18650 light I own besides the SC60 that I can practically carry in my pocket all day long.  That point alone makes it rare these days.   

I said I'd try and keep this short, so I'll stop here.  Thanks for reading.

thanks for the review! I think I am learning quickly that these Yezl lights aren't all they are made out to be (especially in the videos that they host on that chinese youtube site). At least I am not a fan. Others are I'm sure.

Thanks for picking the nits on this one Match. I'm going to order one right after I hit the save button on this post. Oh, and by the way, I would very much like to see the light that you would give 5 stars to!Laughing

Thanks Match for the great review! That is definitely an impressive amount of light from such a compact package, but not very impressive construction for the price. I do expect my lights to survive a few drops. Thanks for your professional opinion!

Nice review Match ..

Nice review, same thing happened to me last week. i just bought an mte m2 and dropped it. wont turn on but i had my x2000 with me so i tried the tail cap and the led lit so i was relieved. opened the switch and found no solder on the pcb to hold the spring on. i soldered the spring on and added solder to the outer ring of the pcb and seems to have done the job.

Great review Match, thank you.

I got Yezl Z1 yesterday and here are some notices:

It has very thin - and much less - threads and body is different - worse - than Brinyte PD08 (which looks the same). But it is crazy bright and fits a pocket so as long as its threads are ok and nothing breaks, I very much like this light.

How much is shipping to the US for one flashlight typically?

If you order multiple lights is the shipping only a little more or does it go up a lot?

Take a look at the AURORA SH-032

That´s my next modding project for XM-L.

p.s. Reflector of the Aurora is 20x20mm, all other "EDC XM-L´s" have 18x12mm and it´s stainless steel Wink

I've got one, and it is a very nice light. Review here. Heat is going to be a very big issue in an stainless steel body. Keep the current down - I suspect an XP-G R5 with the stock driver would be better.

 

The numbers from my light tests are always to be found here.

Andi thanks,
 
It’s good too, 

but I think  AURORA SH-032 Wight its is 104g. rather more for EDC

UltraFire P10 weighs only 52g.

True, but it is a very, very nice light - just not one to mod with a high-power LED.

And driver KD 8* AMC7135 Circuit Board?

That would be better - it would lose more heat. But I like my one the way it is...

 

It would be a pretty easy light to mod.

Wow that's weird Mine has the longer threads like the bryinte on the right .. It is 6 full turns before it drops off the threads .. The head side does look a little bit shorter threads and went 5 turns before it fell off the threads . Wonder if your tube is just flipped around?? ..I do  like my bezel ground down  smooth  it looks and feels much better ..My biggest complaint with this light (xp-g version )Is the body,specificly the center tube  The flat spots on the body makes it slicker for no reason ,just so they have a place to advertise .What I want is just  all knurling . This is the same reason I'm afraid to buy the D-11 Nitecore ..Silly flatspots  

Send me your bezels ..

No, it isn't flipped, it is a different body. Even the lanyard holes are ultra thin on Yezl. I suspect different batches or even built by different factories with the "same"(!) specs...

I received my AW 2900mAh protected li-ion and 1600mAh IMR cells yesterday. With a full charge, the protected li-ion puts out the rated 2.5A but the IMR does a full 3.5A on high. I noticed that there is almost no difference in brightness from 2.5 to 3.5 amps. After doing some reading of Crees product sheets, I see that the XM-L is rated at a maximum current of 3A. It doesn't say what happens when you go beyond that.

One thing I did notice, the head of the light would get absurdly hot in seconds but with the protected cell at the right current, it was a bearable amount of heat.

Am I turning my light into a heater with the IMR cell with no increase in light output?

Yep. You practically have to solder the XML directly to a giant block of copper and cool it with a fan to get good results at 3+ amps.

Got mine also today.

After a few minutes on high, it gets very hot.

Is this still safe for the battery, I don't want it to explode in my hands.
