I don’t normally review “budget” lights, but the Xeno E03 specifications show a lot of potential for the price. Does it live up ito these specs? Scroll on to find out, gentle reader … :whistle:

The light comes in a nice presentation style metal case, with black packing foam. Inside, you will find the light, manual, simple wrist strap, extra o-rings and switch.

From left to right: Duracell AA, Xeno E03, ITP SA1, Klarus ST-10, 4Sevens Quark AA, Nitecore D10, Fenix LD10, Zebralight SC51

E03:: Weight: 48.1 g (no battery), Length 96.7mm x Width 21.5mm (bezel)

The overall dimensions are pretty standard for a typical 1xAA light.

Build of the E03 is remarkably good for the price. Of immediate note, notice the polished aluminum bezel ring, square-cut threads and dual body o-rings. :thumbsup: You also get a GITD switch boot cover and GITD o-ring in the bezel.

In addition, screw threads are anodized for tailcap lock-out. Although not shown, there is a spring soldered on the positive contact plate in the head, so flat-top 14500s will work fine. :)

The tailcap switch is a reverse clicky, and has a plastic retaining ring (well, you can’t have everything at this price point ;)). Switch feel is about typical for a reverse clicky, and the light can tailstand stably.

Knurling is surprisingly good – this is one of the more aggressive patterns I’ve seen on a made-in-China light, but it doesn’t feel like it would be too rough on clothing. The E03 also features a unique grip feature – finger grip indentations on one side of the battery tube. I found these to be well placed for over-hand operation.

Anodizing was perfect on my sample, no chips or smudges (note the light also comes in blue and red). Lettering is sharp and clear, bright white on the gloss black background.

The diffuser cone is an optional accessory, and doesn't come with the light. It does the intended job well.

My general impression of the build of this light is very positive – it feels like a far more expensive offering. :thumbsup:

The E03 comes in a choice of emitter types, and my review sample is the XP-G R5 Neutral White. This is actually the first R5-output bin Neutral-tint I’ve seen (most are usually R4s). Note that it is a 3C tint bin, so it is not as warm as the typical 4A/B-5A/B “Neutral” white tints. But I personally quite like it – I am not a fan of overly warm tints, and this 3C is just about right in my books.

All lights feature a medium textured orange peel (MOP) reflector

Which brings us to the requisite white wall hunting ;). All lights are on Hi on Sanyo Eneloop, about ~0.75 meter from a white wall (with the camera ~1.25 meters back from the wall). Automatic white balance on the camera, to minimize tint differences.

As you can see, the beam profile of the E03 is reasonably smooth and even. Although not as heavily driven on 1xAA as the Fenix offering, output is quite reasonable for this class (scroll down to my Summary Tables and runtimes for more specifics on output).

UPDATE: Here are some shots without and with the diffuser (f2.7, 1/100sec exposure for both):

E03035.jpg


Personally, I like this diffuser better than most other wand ones. The flat top gives you a very even beam - a lot of the conical ones tend to still produce some centre throw. Although my preferred diffuser is always a thin flat one over the lens. But note again that the diffuser does not come with the light - it is an optional accessory to be purchased separately.


User Interface

The UI is strait-forward. Turn the light on by pressing and releasing the tailcap clicky. Switch modes by soft-pressing.

The mode sequence is Med > Lo > Hi, in repeating order. There is no memory, and the light always comes on in medium.

And that's it - no blinking modes, no complex interface. It is very reminiscent of some of the basic Fenix and ITP keychain lights.

PWM and Strobe

The E03 appears to be current-controlled on its low modes - I could find no evidence of PWM. :)

Testing Method:

All my output numbers are relative for my home-made light box setup, a la Quickbeam's flashlightreviews.com method. You can directly compare all my relative output values from different reviews - i.e. an output value of "10" in one graph is the same as "10" in another. All runtimes are done under a cooling fan, except for any extended run Lo/Min modes (i.e. >12 hours) which are done without cooling.

I have recently devised a method for converting my lightbox relative output values (ROV) to estimated Lumens. See my How to convert Selfbuilt's Lighbox values to Lumens thread for more info.

Throw/Output Summary Chart:

Effective November 2010, I have revised my summary tables to match with the current ANSI FL-1 standard for flashlight testing. Please see http://www.sliderule.ca/FL1.htm for a description of the terms used in these tables.

E03-FL1-Summary2.gif


E03-FL1-Summary1.gif


As you can see, output levels and throw in my testing are very consistent for the class on regular batteries. On 14500, the E03 is a real barn-burner on Hi. :eek:oo:

Output/Runtime Comparison:

1AA5-MedEne.gif

1AA5-LoEne.gif

1AA5-HiL91.gif


1AA5-HiAlka.gif

1AA5-MedAlka.gif

1AA5-LoAlka.gif


1AA5-Hi14500.gif

1AA5-Med14500.gif


Now this is interesting - the output/runtime performance pattern is remarkably similar to the Fenix LD10. :eek:oo:

While it is true that max output on regular alkaline/NiMH is not as high as the LD10, the runtime curves look the same. And on Med, the output level and runtime is virtually identical (with a slight advantage to the E03, likely due to the R5 output bin).

Where the E03 differs is on how it handles 14500. On Med, the E03 is actually identical to the Fenix LD10 on all modes (i.e. direct drive). But on Hi, the E03 is even brighter than the Fenix (!), and on Lo has a reduced output level.

---------------

UPDATE March 24, 2011: For those of you who have asked, here is how the E03 compares on standard batteries, 14500, and the new primary lithium Titanium Innovations 3V 14505. Note that these are not ANSI FL-1 lumen estimates, but initial values upon activation.

----------------

Potential Issues

The light lacks true low modes on 14500. Max output on 14500 also seems unusually high.

Light uses a simple UI, with no memory and a Med > Lo > Hi sequence.

Screw threads are square-cut, but at coarser level than typical (i.e. relatively few threads, spaced further apart than typical).

Preliminary Observations

I will come right to point - for $28, I think this light is a steal. I have seen lights twice this price that don't match the build quality or output/runtime characteristics of the Xeno E03. :thumbsup:

Frankly, this light gets it right on just about every measure. The build is outstandingly good for the price. Not just a knock-off, the E03 has some nice specific features (e.g. very good knurling, built-in finger wells, GITD accessories, etc.).

Having the choice of emitter is also great. As previously mentioned, this is the first XP-G R5 Neutral White I've seen (most are R4s). I personally really like the tint on my sample - it uses a 3C tint bin, so it's not quite as warm as the more common 4/5 tint bin Neutrals. But you can also get it in XP-G R5 Cool White (1B) or XP-E Q3 Warm White (7B).

The circuit performance was a very pleasant surprise for the price - on standard batteries, you basically get Fenix current-controlled efficiency, and at generally comparable output levels. :twothumbs And extra bonus - on 14500, you get to keep defined output levels on the E03, albeit at much brighter levels. In contrast, on the Fenix you loose all defined levels on 14500.

I wish more multi-level lights would use this method of output level control (i.e. preferred over the less efficient PWM). Of course, you need to expect some minor tint shifting over the output levels with current-control.

The interface is one area that seems somewhat basic compared to all the other advanced features of the light. Although Med > Lo > Hi is common on consumer-oriented lights, I would personally prefer Lo > Med > Hi with a memory mode. But that wouldn't stop me from recommending this light for the general user. :)

I was originally reticent to accept this light for review, given the "budget" price point. But the E03 certainly proves you can't judge a light by its price. Still, availability and consistency over time (and over multiple batches) can be concerns with lights in the budget class. However, for right now, I consider this current build to be an outstanding value as a general purpose light. :wave:

UPDATE May 30, 2011: Xeno has recently upgraded the E03 line to now include Cree XM-L emitters. Although I haven't directly tested the new versions, you should reasonably expect greater output for equivalent runtime on Max with the XM-L, especially on 14500 Li-ion/14505 lithium. However, due to the floodier beam of the XM-L, this may not appear too noticeable at a distance (i.e. will be more noticeable at close/confined distances - where you are frankly unlikely to be using Max). Lower levels are likely to be the same efficiency as the XP-G emitter. I don't know whether output at Lo/Med are increased compared the XP-G versions, but the difference isn't likely to be huge, in either output or runtime (but will again be less throwy on the XM-L). As such, I would recommend you choose between the XM-L and XP-G versions on the basis on the beam pattern (i.e. flood vs throw, respectively).

-----

UPDATE July 20, 2011: I have just tested a XM-L-based E03 (Neutral T6), comparison results below:

Original E03 is the XP-G Neutral R5 version.

ST5-Hi-Alka.gif

ST5-Med-Alka.gif


ST5-Hi-14500.gif

ST5-Med-14500.gif


In summary, the new XM-L version has a broader and less defined hotspot, making the light seem "floodier" (i.e. less throw).

On standard batteries, max output has increased somewhat (for equivalent runtime), but you may not notice the difference given the floodier beam. At lower levels, output and runtime are equvalent between the XP-G and XM-L versions.

On 14500, output has increased at ALL levels. The Hi level is now insanely bright, and not something I would recommend running the light at (i.e. heat will be an issue, potentially damaging the light or the battery). The Med level on the XM-L is now slightly brighter than the Hi of the original XP-G version, :eek: and the Lo on the XM-L is slightly brighter than the Lo of XP-G verison (with again equvalent runtime). So, basically, you gain a very temporary "burst" Hi mode on this new XL-L version, but loose the old Med mode.

Hope that helps!

Thank you for the review, Selfbuilt!

I'm glad to see that they offer the same model with different tints, it would be great if we saw more of that.

In a light like this I think it's good with only 3 (or 4) levels and no blinking.

I have before said that I prefer low-med-high but my ITP A3 and LD01 is med-low-high and I do think it's pretty good. Mostly I use medium and in case I need low I just cover the front and do an extra twist.

This is the same but clicky. I have to try it. Could also be a good light to give to non flashaholics.

+1 another thank you Selfbuilt.

I bought the neutral tint and use the 14500 protected cell. It is nice to see those graphs, and have run times.

I agree with the high quality for the price. Where can you get a neutral AA light for $28, + 4.2V capable?

Great gift with a L91 cell, or the new 3V Titanium Innovations primaries. Great tint!

I was glad to see your review of this light. Very good as always. Out of curiosity, I picked one up when the first came out. What got my attention was the choice of tints. Yes....I'm one of those warm tint fans. Mine is a nice yellow, as compared to the orange/peach tint of my 4sevens lights. I finally broke down and ordered a couple 14500 cells but as your review shows, this isn't a bad light at all on primaries.

The warm tint option makes this very tempting, though I would prefer a more orange than yellow shade. Thanks for pointing out this sleeper, selfbuilt. As usual, an excellent review.

I recieved the 14500 batteries I had ordered for the E03. As mentioned before, I have the warm version. It does very well on Eneloops and on 14500 cells, it's very bright. What is nice is that you can switch between cells, depending on your lighting needs, and in a pinch you can easily find AA's anywhere. For a budget light, this is a beauty IMO.

Thanks for this excellent review on a nice and frankly surprising light!

Selfbuilt, did you get the impression running continuously on high with 14500 cells is "safe"? :confused: The light has to dissipate about 5 watt of heat power: 3,7V * 0,75Ah / 0,5h (and about 80%-90% of this is heat, the rest is light).

This light is very nice as gift to non(not yet?)-flashaholics! :thumbsup: And the barn-burning capabilities on 14500 are really tempting for me to try this cell size - currently I only have AAA/AA Eneloops for EDC lights and 18650 for the bigger ones.

The only thing missing for me is a deep carry pocket clip - i even "upgraded" my Preon ReVO with the clip from an ITP A3 Titanium...

That is an excellent question. Personally, I worry about small lights driven this hard, for just that reason. There's also the (theoretical?) risk of thermal runaway for the emitter.

It is really hard to say what is "safe". But I would share your concerns about running this light on Hi on 14500.

It should be possible as manufacturer to measure the temperature directly at the LED while running on high - to make this realistic the sensor and it's wires to the outside of the light would have to be placed so that the heat dissipation is not altered.

I don't think this is possible without drilling some holes into the flashlight and filling them up before measuring - removing the lens would change the heat dissipation capability.

Even nicer would be a permanent temperature sensor like in processors to "throttle" output when the flashlight (emitter or circuit) would otherwise overheat - the 4Sevens Maelstrom S12 and the Jetbeam RRT3 have that feature :drool:

Cool review as always Selfbuilt!! Thanks a lot.

Wow, I badly need I couple of those E03! Anybody here knows where to purchase black ones in neutral and warm tints?
