       First of all I would like to say a gracious Thank You to
       ThruNite for the opportunity to review these lights on their
       behalf. Both of these lights were supplied by ThruNite for
       review.
       This is my very first review of any flashlight products. It will
       be far from perfect and lacking any detailed analysis which can
       be found in some of the elite reviews. I will however, try to
       give an honest opinion and try to be as professional as possible
       with my limited equipment and experience.
       I apologise in advance for my pictures and camera quality. It
       was difficult at best to convey the images the way I wanted you
       to see them. My goal in the near future is to acquire a manual
       focus camera system for ease of use and quality.
       Thank you for your understanding.

       Initial impressions
       The lights arrived very speedily from ThruNite, they were well
       packaged and undamaged. This is what I found when I opened the
       box.
       Two very well presented and professional looking cases. Upon
       inspecting the cases, they appear to be well built and very
       sturdy.
       The lights themselves inside were a nice snug fit with plenty of
       soft padding to protect them incase of the unforeseen ground
       magnets.

       Supplied as standard accessories with each light were
       1x Belt Holster
       1x High quality lanyard
       2x Spare rubber O-rings

       ThruNite TN31

       Here are the two lights out of their boxes and sat side by side
       for a direct size comparison. As you can see, the TN31 is
       substantially larger than the TN30.
  HTML http://img812.imageshack.us/img812/9458/sizecomparisonm.jpg
       In this next image, you will see why the TN31 is larger than the
       TN30, This is due to the rather large diameter and very deep
       reflector fitted to the TN31.
       This allows for a very tight beam and hotspot for the maximum
       throw possible with minimal losses.
       In fact, the ThruNite TN31 XM-L2 is one of the longest throwing
       Standard Production Single LED Flashlights available on the
       market today.
  HTML http://img850.imageshack.us/img850/387/lenscomparison.jpg
       Styling & Features
       Both the TN30 and the TN31 share the same design rear body, rear
       clicky master on/off switch and battery carrier. They also share
       the same User Interface for mode/brightness selection.
       This is achieved by rotating the magnetic ring located just
       under the head of the lights.
       Here you can see the mode selection ring which has six
       brightness levels, ranging from moonlight mode (1 lumen) all the
       way up to level six (maximum output).
       Turning this ring allows for full control of output brightness
       in real time, thus no need for ‘Stepping’ through modes with
       partial clicks on the rear switch.
       This is a very well thought out design, especially as these
       lights are a fairly large carry in the hand. Attempting to
       change modes with the rear clicky, although possible would be
       very cumbersome indeed.
       What I particularly liked about this design is that you’re able
       to easily change brightness levels comfortably one handed as the
       hand rests naturally with the thumb and fore-finger perfectly
       seated to twist the control ring.
       Unfortunately the levels 1-6 are not marked under the control
       ring as are Standby and Strobe. Just personal preference I
       realise, but it would have been something I would have
       appreciated.
  HTML http://img829.imageshack.us/img829/316/selectionring.jpg
       Both the TN30 and the TN31 have what I would call very sleek
       styling.
       The TN31 is less aggressive looking around the head, but this is
       mainly due to the fact that the TN30 pulls a lot more power and
       needs to dissipate much more generated internal heat.
       Here you can see the difference in the head design around the
       heatsink fins. Both are machined to an exacting standard with
       very deep grooves to allow adequate airflow between the grooves.
       Thrunite TN30 (notice the more aggressive heatsinking potential)

       ThruNite TN31
  HTML http://img835.imageshack.us/img835/1821/tn31anodizingandheatsin.jpg
       Both lights share the same tailcap design shown below. It’s
       worth noting that the lights will tailstand with no problems
       since the switch itself is nicely recessed.
       You will notice that there are cutout indents (crenelations) in
       the tailcap itself which enables the lights to be easily
       activated if being used in a ‘Overhand’ grip.
       This also makes using the forward clicky tactical partial press
       activation much less cumbersome.
       I will note though at this point that my wife was unable to
       activate the switch with an overhand grip without losing grip of
       the light itself.
       You will need ‘fairly’ large hands to accomplish this easily
       without fear of dropping the light.
  HTML http://img252.imageshack.us/img252/5553/tailcapcomparison.jpg
       Another difference worth mentioning is the business end of these
       lights. The TN30 has a discreet bezel which is anodized
       Aluminium and integral to the head itself.
       Whereas the TN31 has a very shiny Stainless steel bezel with
       prominent styling.
       This offers a touch of class to the overall look of light and
       somehow gives the impression that the diameter of the light is
       larger than it really is. Just a small design touch that
       impressed me personally.

       TN31 Bezel

       You may have also noticed the discreet cutout indentations
       (crenelations) on the bezels of both lights, this allows light
       to escape if the lights are accidently left running when face
       down.
       Below shows the lights both left running and facing down in a
       darkened room.
  HTML http://img401.imageshack.us/img401/3889/bezellightescape.jpg
       Design, Workmanship & Build Quality
       Overall, the design and workmanship on the these ThruNite lights
       are exemplary with very few negative points to mention, however
       there are a few.. I will get to those a little further on.
       As far as the exterior goes, there are no noticeable
       imperfections on either of the lights. The Hard HAIII anodizing
       is absolutely perfect on both lights with no anodizing missing
       between grooves and no light spots of thin anodize anywhere to
       be seen.
       I have checked them both thoroughly and honestly, they’re
       perfect.
       When removing the tube to access the battery carrier, it feels
       very tight and concise on the threads and with a very positive
       feel on the O-ring.
       It grips nicely and was perfectly lubricated as were the threads
       on both lights.
       The threads themselves are very course with a Trapezoidal cut
       with absolutely zero grittiness.
       Below you can see the quality of the threads, these are
       identical on both the TN30 and the TN31
  HTML http://img542.imageshack.us/img542/8633/threadquality.jpg
       The knurling on the battery tube provides excellent grip without
       offering any discomfort.
       I found this to be a very important detail as it allows the
       lights to be carried over long distances without causing muscle
       fatigue in the forearms.
       I was able to carry the TN31 (the heavier of the two) on a 5
       mile round trip with surprising ease.
       This is an important factor for prolonged use due to not having
       to use excessive force to ‘keep the light safe’ from dropping.
       Below you can see the depth of the knurling which offers
       precisely the correct abrasion.
  HTML http://img138.imageshack.us/img138/1148/knurlingquality.jpg
       Once the battery carrier is removed, it’s immediately noticeable
       how well it is constructed.
       I’ve read several reviews of the TN30 and TN31 and each one has
       Aluminium ends. Mine both had thick solid brass ends, not only
       on the battery carrier (both ends) but also on the bottom of the
       pills (on both lights)
       The design of the battery carrier is clearly well thought out
       with sturdy construction and what looks like Carbon Fibre
       supporting struts.
       On the lights I received, all the screws were fully tightened
       and the contacts were all clean.
       There are no flickering issues and neither of the lights dim or
       turn off when the side is tapped. I know this has been an issue
       in the past and it looks like ThruNite has managed to rectify
       this issue with the current production of their lights.
       Below are pictures of the battery carrier and the bottom of the
       pill. The pill battery connection is identical on both lights.

  HTML http://img819.imageshack.us/img819/119/batterycarrier2.jpg
  HTML http://img10.imageshack.us/img10/7450/pillbasebrass.jpg
       The reflectors in these lights are clear with a highly polished
       look. Both lights have the SMO (Smooth) reflectors.
       The TN30 triple reflector is much more shallow in depth when
       compared with the TN31 but is still fairly noticeably deep when
       compared to most other Triple LED style lights.
       As a result of this, the TN30 although being primarily designed
       for Flood, offers surprisingly exceptional throw for a light in
       it’s class.
       The LED’s were perfectly centered within the reflectors on both
       the TN30 and the TN31

       Finally, before I mention the minor issues and offer the
       beamshots, I would like to give you an idea of the head size
       difference between the TN30 and the TN31
       ThruNite TN30

       Beamshots
       Here are the comparison beamshots taken at different ranges and
       with different backgrounds in an attempt to highlight the tint,
       brightness and throw capabilities of these lights.
       Also, thrown into the mix for direct comparison purposes is my
       very bright XM-L Aspheric thrower. 2800mA nanjg 105c 8×7135 XM-L
       U3 LED
       *Please note* With the limited capabilities of my camera, I was
       unable to get true ‘real life brightness’ images. All of the
       following images are very slightly darker than ‘real life’ naked
       eye brightness.
       All shots below are taken with the lights at their Highest
       Brightness settings

       ThruNite TN31 XM-L2 U2
  HTML http://img842.imageshack.us/img842/9720/tn31.jpg
       As you can see, both the TN30 and the TN31 completely destroy
       the Aspheric thrower in terms of overall light output and spot
       brightness.
       But what about over a longer distance ? surely the Aspheric
       thrower will be able to compete against the TN30 ? after all the
       TN30 isn’t specifically designed to throw.
       Well let’s see.

       So there we have it, The TN30 and the TN31 both beat the
       dedicated Aspheric thrower. Not overly surprising I know but I
       did expect the Aspheric to come a little closer than it did.
       After all, this thing is no slouch, it’s well driven and
       properly heatsinked and is Very bright, just not in a same
       ballpark as the ThruNite lights.
       So, next up is an attempt to portray the colour tint of these
       ThruNite TN30 and TN31, they both have a very warm and natural
       tint.
       It’s difficult to portray this in the images but with the naked
       eye, it’s easy to see how they bring out the natural greens and
       yellows in plant life and vegetation.

       Distance: 4m
       Here is portrayed the beam pattern of each of the lights on my
       barn wall.
       The barn wall is about 200 years old so the reflective quality
       isn’t what it once was but nevertheless, it gives an honest
       impression of the beam profile of each light.

       With the beamshots out of the way which I hope you found useful
       the only things left to detail are the minor problems discovered
       as mentioned earlier, and relatively minor they are.
       Both lights had a slightly wobbly control ring but nothing major
       as to cause any ongoing issues that I can see. I know this has
       been mentioned many times in the past in previous reviews and it
       looks like it still hasn’t been addressed.
       Whether this is due to the integral design and cannot be
       addressed without a complete design overhaul, I really do not
       know.
       With the price range these lights find themselves in, and with
       the very high standard of workmanship on the whole, it would be
       nice to see a solution at some point in the near future.
       Aside from the wobbly control ring, the ThruNite TN30 was
       absolutely flawless in every way.
       Not so however with the ThruNite TN31..
       The TN31 I received has a couple of minor issues. Pretty much
       cosmetic from my own point of view but needless to say, for the
       price of the TN31 new, these quality control issues shouldn't be
       allowed to slip through the net.
       The main problem I have found with the TN31 is condensation on
       the inside of the glass lens. Whenever the light is taken into a
       cold environment, the front lens fogs up quite badly.
       It takes more than half an hour for the fogging to subside to a
       half inch diameter and I haven’t been outside with the light
       long enough to find out how long it takes to fully dissipate the
       fogging.
       I can only assume the light was assembled in a damp environment
       and the problem is always going to be difficult to contend with
       due to the volume of air inside the reflector cavity, but I can
       certainly say that the TN30 does not suffer from the same
       problem in the slightest.
       Perhaps it’s not a common problem and is only an issue with the
       light I received, I’m not sure. I haven’t seen this mentioned
       before so who knows.
       The next problem I had was a badly damaged O-ring seal upon
       opening the light for the first time, although to their credit,
       ThruNite do supply two spare O-rings.. Thank you Thrunite!
       I replaced the O-ring and all has been fine since. (perhaps this
       is linked with the condensation)
  HTML http://img543.imageshack.us/img543/2446/tn31oringdamage.jpg
       The final problem to mention was with the reflector. There
       appears to be some kind of spotty residue on the reflector
       itself.
       It’s barely noticeable and does not affect the beam or cause
       artefacts in any way. I only noticed it when it caught my eye in
       a certain light. However, here is a picture of what it looks
       like.
       *Please note* These spots are not on the front lens, they are on
       the reflector itself. I have not opened the head of the light so
       I do not know what it is. Fungus perhaps ?

       Overall though, with the minor problems mentioned above, it
       certainly does not detract from the performance and build
       quality of these lights.
       They are both very well build, very sturdy construction and
       perform to a mind boggling standard. If any further issues
       arise, or if there is anything I have forgotten to mention, I
       will be sure to update this post.
       My conclusion is that despite the high-ish price bracket these
       lights fall into, they are well worth the money and once you get
       your hands on either of them, you will see why.

       UPDATE
       I am now 100% certain that the condensation problem and
       reflector particles were due to the damaged O-ring.
       The particles on the reflector it turns out were very tiny water
       droplets and not any kind of fungus. *good news*
       I’m happy to say that since completely drying the moisture from
       the head of the TN31 and replacing the O-ring. There are no
       longer any condensation issues and the tiny particles have gone
       completely.
       I now have a 100% perfect ThruNite TN31 and I absolutely love
       this flashlight, it blows me away everytime I use it.
       My hat is off to ThruNite for the amazing quality of the
       products they manufacture.
