Warning: pic heavy, as usual 
UPDATE SEPT 19, 2010: 100-Yard beamshots added to this review.
The Tiablo A9 has been something of a standard in the "thrower" flashlight world. It has been around for around almost three years now, and its build has remained relatively stable (with a Cree XR-E Q5 emitter). Although I haven't done a stand-alone review, the A9-Q5 was included in my earlier Thrower Round-Up Review. About a year and a half ago, an optional aspherical optic head (collimating head) was developed, for maximum throw.
Despite the launch of new "thrower" lights (e.g. Tiablo A10-G), Tiablo has continued to produce this simple, straight-forward thrower at a reasonable price. Today, an updated version of the A9 has been released, sporting the latest single-die emitter, the Cree XP-G R5.
Note that the original A9-Q5 version is also still available - Tiablo hasn't discontinued it, but offers the A9-R5 as a "special edition".
Manufacturer Specifications: (taken from the Tiablo website).
The light comes in the standard Tiablo hard cardboard box, with attached rubber grip ring (removable), manual, warranty card, GITD boot cover, good quality wrist lanyard, and extra o-rings. For this review, Tiablo also sent me their standard aspheric head:
The aspheric optic head hasn't changed from before. Those of you who already have one of these from the earlier A9-Q5 edition can relax, it still fits fine on the newer A9-R5 model as well.
From left to right: AW Protected 18650, Tiablo A9-R5, A9-Q5, A10-G, 4Sevens Maelstrom G5, Dereelight DBS.
The external build of the A9-R5 doesn't seem to have changed from the earlier A9-Q5. Except for the new emitter (and raised plastic contact disc in the head), it looks pretty much the same.
However, Tiablo informs me that seal for the front lens has been improved on newer models (they claim to have tested it up to 22m under water without failure). Anti-shock has also been improved, and they report the light survives 7m drops onto concrete.
The light features anodized screw threads, allowing for tailcap lock-out.
Letter is sharp and clear, bright-white against the black matte background. Anodizing is type-III HA.
The tailcap spring is encased in a gold-plated contact cover. The light comes by default with a reverse clicky light, but a single-stage forward clicky switch is also available.
The emitter appears to be well centered on my sample.
Beamshots
Sorry for the quality of the white wall beamshots – I've recently moved, and haven't had a chance to set up a proper beamshot closet yet. What you are looking at below is un-primed drywall, with a range of spakle/sanding marks.
Here are some up-close shots comparing to the original A9-Q5 to the new A9-R5. Both lights are on an AW protected 18650. To start, here is ~1m from the wall:
To better show you the hotspots, here is a close-up taken when the lights are ~5m away.
As you can see, the original A9-Q5 is more focused for throw (as expected), with a broader hotspot on the A9-R5. The newer XP-E/XP-G emitters are built differently from the earlier XR-Es, and don't typically focus as well. But on the flip side, the beam profile of the new A9-R5 is nowhere near as ringy as the original.
Although these shots don't show it well, the A9-R5 is brighter overall compared to the A9-Q5 (the difference becomes more marked over the course of a 1x18650 run). Scroll down to my runtimes for more info.
How about the aspheric optic? Here we go again at ~5m, with each light maximally focused.
At peak focus, and aspheric optic produces a clear outline of the actual emitter die. The A9-R5 does not seem to produce as bright or as sharp a die image as the A9-Q5. However, there is less evidence of the chromatic aberrations that are common on A9-Q5 emitters (i.e. the blue, yellow, and magenta fringing).
UPDATE SEPT 19, 2010: I've added some additional lights to my 100-Yard Outdoor Beamshot Round-up, including the lights in this review. Check out that round-up thread for more details. Here are a couple of animated GIFs of relevant comparisons:
User Interface
This hasn't changed on the A9-R5. With the standard reverse clicky, click and release for the light to come on in Lo mode. Click and release again for it to advance to full power. Click again to turn off.
The original A9 didn't feature a multi-level circuit (rather, the Lo mode was created by a resistor in the tailcap). This revised A9 XP-G R5 appears to work the same way, as you need to click through the tailcap to move through modes. The "dual-mode DC-DC regulator" in the specs must refer only to regulation on the Hi mode.
Consistent with this method operation, I was unable to detect any sign of PWM on either mode.
There is no strobe/SOS modes.
Testing Method: All my output numbers are relative for my home-made light box setup, a la Quickbeam's flashlight reviews 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.
Throw/Output Summary Chart:
All throw measures above were taken at 5m and extrapolated back to estimates at 1m. 1m actual measurements would give you highly misleading results, as the beams of thrower lights don't have time to converge by that distance.
Also, my throw numbers may be lower than some - I take all readings from the center of the die image. If you "hunt around" the border areas of the die image segments, you can get regional pockets that score much higher However, since it is hard to reliably identify these, I choose instead to stick with the center of the die.
Note that the output level of the Lo mode is variable, depending on battery source used.
Output/Runtime Comparison
Note: Effective January 2010, all CR123A runtimes are now performed on Titanium Innovations batteries. You can compare the performance of these CR123A cells relative to the Duracell/Surefire cells used in my earlier reviews here. These new light results are marked by an "*" in the graph legend
Basically, the overall performance characteristics of the A9 haven't changed - the overall output has simply increased.
As before, the light is fully regulated on Hi on 2xRCR/CR123A and appears to be direct-drive on 18650 at a slightly lower output level (as is common on multi-power lights).
On Lo, the light's tailcap resistor produces a classic slowly dropping off pattern. The resistor reduces the output on Lo by differing amounts, depending on the battery source used (only 18650 is shown above).
Potential Issues
In keeping with its older design, the A9 is a single-stage circuit that uses a resistor for its Lo mode. This is less efficient than most modern multi-stage circuit designs. It is also more variable, as the resistored-Lo output level will vary depending on the battery source used (i.e., on the input voltage).
While overall output has increased, throw is not as great as the earlier XR-E Q5 version (as expected for a XP-G). Throw with the aspheric head is similarly reduced compared to the earlier Q5 version.
Preliminary Observations
The Tiablo A9 has remained one of the more popular "budget" builds in the multi-power thrower class of flashlight. Its longevity is a testament to its simplicity. Of course, the resistored-Lo mode may be a surprise to many here who are used to modern circuit-controlled multi-level lights – but it gets the job done. :shrug:
The XP-G R5 upgrade gives you a nice bump in output compared to the standard XR-E Q5 version. Tiablo has done a good job in maximizing throw while minimizing beam rings on the A9-R5. :thumbsup: However, consistent with the build differences of these emitters, the XP-G R5 has less throw compared to the XR-E Q5 (true for both the standard reflectored head and the optional aspheric head).
Still, throw is actually excellent for a XP-G-based light. On 1x18650, the A9-R5 matches the throw of my 4Sevens Maelstrom G5, although with a bit less overall output. On 2xRCR/CR123A, the A9-R5 pulls ahead slightly in terms of throw (while still being somewhat lower overall output). Note that the A9-R5 also has a wider and dimmer spillbeam than most lights, due to its larger reflector.
The aspherical head results are interesting, as there is a lot less blue/yellow/purple fringing when the optic was used on the A9-R5. :thumbsup: While absolute throw is lower than the A9-Q5, I still consider this an improvement – it throws a nicer beam profile. This is especially true if you slightly defocus the optic to remove the "space invader" look of the die-projection.
The new XP-G R5 is a functional and serviceable upgrade – in terms of output and beam pattern - to the standard A9-Q5. Throw is reduced however, so it is important to consider what matters to you in this class of light.
