It is hard to tell you what the precise ratio is, but the D25a has it. I have written about this before, but there is a magic ratio between diameter and length and some lights hit it dead on and others do not. I will note, though I don't think it is an issue, that this light has some really thin body tube walls. The reflector and emitter are really well centered. Many of the parts of the light are really quite nice, especially the knurling and the interior of the light's head. A little bit better attention to detail could have resulted in perfect fit and finish. The clip being off-centered does impact the carry a little. The threads on the head are a little sloppy and the pocket clip is attached but off centered. Okay, lots and lots of features, good output, but the fit and finish is not QUITE there, even on the "special edition" Ti version. It has received an average of 5 stars out of 5 with 3 reviews. Here are the Amazon reviews for the D25c. There are no English language video reviews of the D25a or c. Here is a written review of the D25 18650 version. They also got me the light in three days and shipping was free. I got mine from Illumination Gear, and they have the best price I could find on the Internet. I would imagine the clicky versions will be a bit longer. The D25c (the CR123a version) and the double AA version will also be released in a clicky this year (the regular version are all twisties). The difference in output doesn't really make much of a difference, but it does impact the beam type and shape, as the XML is a much bigger emitter than the XPG.
All of these lights were released with XPG cells, and many of them now run XML emitters. There are two limited edition versions-Ti versions of both the single cell CR123a and the single cell AA version. There is a CR123a version, a double CR123a light, a 18650 light (that can also run two CR123a batteries), and a double AA version.
#Eagletac d25c clicky titanium series
Here is the EagleTac D series product page. The single cell AA flashlight is finally up to snuff for the majority of users. It can do everything I described above and it does it with style-or at least the Ti version does. That makes the D25a light, for the first time I have found, a single cell AA light that, on high, hits an actual lumen rating at my preferred high output. After 90 seconds it drops down 20% to 98.4 lumens. Sure other lights had similar outputs (see: Nitecore D11.2), but this is the first (or one of the first) light to conform to the ANSI standard (which is a more rigorously defined measurement, requiring a specified output for a specified time measured from a specified distance). It also, probably, has to do with makers being a little optimistic, shall we say, in their lumens ratings.Īll this being said, I think that the EagleTac D25a series lights represent the first truly capable single cell AA EDC light. This has to do with the difference between emitter lumens and out the front lumens as well as the beam styles (which don't alter the lumens ratings, a measurement of total light output, but do change how bright our eyes see the light-a tighter beam is seen as brighter, it also throws farther). Some makers might claim 100 lumens or more, but the out the front numbers were significantly less, around 60-70 lumens, which while nice is not quite enough to light up somewhat far away objects. The issue with single cell AA lights is that up until very recently the 100 lumen high was not REALLY possible. I'd take 200 lumens on high, but that is not strictly necessary and something of a luxury. A light that could do that would handle probably 99.9% of all of your EDC tasks. This translates into a three tiered output of around 0.5-5 lumens on low, 20-40 lumens on medium, and around 80-100 lumens on high. This means you need a light that won't wreck your night vision, a light that has good flood and while bright, won't blind you, and a light that can light up an object 50-100 feet away.
In reality most people need an EDC light to do three things: walking around at night, close up tasks in the dark, and shining a light towards a source of noise or movement that is well outside arm's reach. It has taken a while and there are few lights out there that handle this task well, but one that I really like is the EagleTac D25a. We have arrived at a point where emitter technology has made it possible to use a single AA cell as a primary EDC light. After a long journey of reviewing more high end or alternatively less readily available items, I have returned to the mainstream of EDC gear with this review-a single cell AA light.
