The T25 model is a brand new addition to Olight's 2008 product lineup. It comes in 2 flavors, Regular and Tactical. Difference between the 2 models are their operating modes, physically they're identical. When Olight initially released their products in 2008, they were the first to introduce a unique hybrid smooth and textured reflector. This time around, they have once again come up with a fresh reflector design. The metal reflector in the T25 has a texture which starts off rough around the bottom, then disperses and becomes more subtle towards the top. The effect of this will be addressed further in the Output section below. Its advertised as using an anti-shattering lens, I'm unable to verify weather its made of glass or plastic. The head on the T25 is noticeably larger than their other models with various machined designs which help with grip when switching modes and levels.

As some of you may have already noticed, the battery tube of the T25 looks strikingly similar to that of the Fenix L2D series. It has has the checkered texture on the top half of the battery tube, but instead of having 2 flat faces machined onto it, the T25 has a third where the clip rests on. The T25 comes with a removable clip which attaches just below the front threading of the battery tube. To remove the clip simply unscrew the narrow textured ring above the clip.The design implemented for the clip was well though out and results in a very securely attached clip while not being a pain to detach. Further down the battery tube, it becomes slightly narrower with lips on either side which provide nice ergonomics for a cigar-type grip. The entire light is coated in Type 3 anodizing which makes if scratch resistant. Finishing is smooth and consistent with no flaws or marks to be found. Threading on all parts are also well cut and smooth, no grinding or squeaking was encountered during tests. The lanyard ring slots in after the tail end threading and is much easier to attach than the one on the NovaTac lights. The tail cap of the T25 Regular houses a reverse push button which feel very nice. Switch travel is just nice, not too long nor too short and it provides a very positive tactile feel and muted, low sounding audible feedback. One of the best switches I've used in a flashlight. The tail cap has a band of checkered knurling about 1cm wide. There're no holes on the tail cap for attachments. The only physical difference between the Regular and Tactical versions of the T25 can be found on the lip of the tail cap. The Regular version doesn't have anything on it while the Tactical version has "TACTICAL SPECIAL EDITION" printed on it.

First up, I would like to talk about the newly designed reflector used in the T25. This is the first Olight product which doesn't use the half-smooth and half-textured hybrid reflector in their other current models. The gradient of texture from base to top of the reflector results in a nice looking beam producing a hotspot which is not as sharply defined, and slightly broader as well. This also removes the blue fringing which appears around the hotspot as seen with the hybrid reflector. The dark ring around the hotspot is still present though. Beam tint from the Q5 WC emitter is a neutral white, leaning slightly toward the cool side at the brightest level. Regulation is maintained very consistently throughout the life of the battery and sharply drops off at the end. Good choice of brightness levels which is twice as bright at each step up.

Here's a rundown of the modes available and how they're accessed.

Constant Illumination:
Click on the push button, cycles through the 5 brightness levels from dimmest to brightest by loosening then tightening the head within 1 second each time. Brightness level is memorized even when powered off.

Strobe:
Half-press the push button while on any level in Constant Illumination mode. Light will strobe on its brightest level. Mode is not memorized, light will revert to constant illumination mode the next time its turned on.

S.O.S. (Low Brightness):
Half-press the push button while in Strobe mode. Light will blink the S.O.S. sequence on low brightness level. Mode is not memorized, light will revert to constant illumination mode the next time its turned on.

S.O.S. (High Brightness):
Loosen then tighten the head within 1 second while in S.O.S. (Low Brightness) mode. S.O.S. sequence will now blink on high brightness level. Mode is not memorized, light will revert to constant illumination mode the next time its turned on.

Here's the runtime graph comparing the relative 190 and 45 lumens level of the Regular and Tactical versions.

The Good - Good runtime and regulation. Very well machined and finished. Accessories such as clip and lanyard ring are easy to remove. One of the best switches I've used in a flashlight.

The Bad - Runtime is slightly shorter than the Tactical version on the relative comparable levels.

The Relative - Beam tint is a neutral white, leaning slightly to the cool side at the brightness level. Hotspot is less defined than other Olight models with hybrid reflectors. Clip designed for head-up carry.
