Whether it is called "TACLITE" or "TRIAD" the different versions of ASP's 2x123 light are so similar that they can hardly be determined by visual inspection. The only relatively recent innovation was the introduction of the tighter focusing so-called "Triad" bulb. It could just as easily been called the "Taclite" bulb and it is distinguished from its cylindrical predecessor by its curved "teardrop" shape.
If the internal focus ASP is really being consigned to the dust heap of flashlight history it will be a shame, because it is truly unique. It has an adjustable, "lockable" internal focusing mechanism, quite ingenious and easy to set. Once set it stays in that focus unless you change it. It is truly a "Focus and forget" design, the only one of its kind.
Because you can achieve an unusually tight focus (which I prefer), the light is remarkably bright, significantly brighter than nearly any other 2 x 123, or even 3x123 light with HOLA. Its only real competition in this regard is the TACM III and PELICAN M6. Even though the focus is tight, the light "splash" from the extreme brightness (at least when the battery is fresh) compensates for the narrowed beam diameter. Of course you can adjust the beam to a larger diameter if you choose.
I do not like the usual style of adjustable focus lights like the Scorpion, because they can inadvertently go out of focus through normal use and during rough or careless handling, or be previously set to a focus which is inappropriate for a sudden current situation. If a light is used tactically or for self defense a predictable beam is essential for quick and accurate deployment.
Beam quality of the Taclite, even if not quite of "Surefire quality" is still excellent, remarkably so for a small unfaceted reflector. The light is water resistant enough to survive strong rain or momentary dunking. It is very solidly constructed of aircraft aluminum with a user friendly foamed vinyl grip. It is easily "locked out" by the slightest counterclockwise turn of the bezel, and has a very smooth, easily accessible but nearly accident proof "clickie" tail cap switch.
It is also one of the most aesthetically appealing small lights. Many people consider it beautiful.
This light is one of my preferred EDC incandescents. (I also carry the E2/MN03 as a fairly bright ultrasmall EDC). My preference for the ASP is in no way a repudiation of other first rate lights out there, especially the Surefires, which are probably the finest and most refined tactical lights in the world. Their beam quality, and that of other faceted reflector lights like the LX Legend and the Streamlight Scorpion are unsurpassed. However, my preference in a 2x123A at this point happens to be for a tightly focused, long throw light. In that respect, the Asp Taclite is IMO one of the three best lights currently produced.
