Body: The battery tube has a band of striped checkered knurling about 2.5cm wide running around the middle. There are also 2 flat faces on either sides which have some branding text printed on. The detachable clip fits towards the front end of the battery tube and slots in nicely into a recessed slot. This slot also has an additional alignment feature which prevents the clip from sliding rotationally around the battery tube. As you can see from the image to the right, the clip only allows for head-up carry, unlike the single-celled models. The battery tube has a recessed region towards the rear end and also a more pronounced lip than the P10C2 which makes it more comfortable when held in a cigar-style grip. Threads on either ends are well-cut, they mate well with both the head and tail cap respectively. The threads towards the front are uncoated as required to activate the low output mode, while threads at the rear end are coated. This allows the light to be effectively locked out when the tail cap is slightly loosened. As with the head, anodized coating is well done, no complaints here. Do take note that the detachable clip does fit tightly around the battery tube, as such, repeated removal and attachment of the clip will cause the anodized coating to scratch off. The tail cap houses a forward push button which allows for momentary activation. Also since all mode changes are controlled via head twists, you can use this light for morse code or other signaling purposes without issues. The switching mechanism is stiff and has an average amount of travel before engaging to the constant on position. When clicked, tactile feedback is positive with an audible click. The spring used for the "-" contact is gold-coated for better electrical contact. On its exterior, the switch cap also has 6 flat faces machined all around providing a good enough grip during battery changes. Due to the small size of the light and clip position, I personally found removing the head a much easier when replacing batteries. The rubber switch cap has a checkered textured knurling and sits recessed inside the tail cap which allows the light to tail stand on flat surfaces. There are 2 shallow scallops machined right on the rear lip of the tail cap which makes pressing of the switch more comfortable. Finally there're 2 small holes for lanyard attachments

Bezel/Head: The EagleTac's T-series has a larger overall diameter. It still has a stainless steel bezel, just like the P-series. It isn't adhered to the head and can be easily unscrewed and replaced if needed. Or it could also allow for various lens attachments in the future such as color filters and beam diffusers. The lens is advertised as being multi-coated glass providing up to 99% light transmission out the front. The reflector used looks very nice with a consistent textured surface and well polished coating. The LED sitting at the bottom is practically perfectly aligned with the reflector upon visual inspection which is nice. Externally, the head is of a subtle conical shape and has 6 flat faces machined all around covering most of the surface. These also act as an anti-roll feature when the clip it detached. The neck area is of a hexagonal ring shape, much like nut. At the rear end of the head is a ring of subtle striped knurling. Looking from the rear you'll see the electrical contact to the battery. A physical reverse polarity protection system in implemented in the T10L so you don't have to worry about accidentally damaging its electronics. Do note that this also means that you will not be able to use the older style flat-topped 18650 cells. Type 3 anodizing is well finished throughout the head with no flaws to be found. Overall the head feels very solid and well made

Output: The EagleTac T10L provides a pretty straight forward user interface, especially when compared to all the multi-mode and variable brightness ramping modes of some recent lights. This will be a welcomed addition to some who just want a light that works without confusing the general user. With the head tightened the light is in Hi mode, advertised at 255 lumens. Loosened puts it into Lo mode, advertised at 60 lumens. The T10L will accept any 3.7V 18650 cell.

Although it would be common to assume that the larger reflector of the T-series would provide a tighter beam and better throw, this is not totally true with this light. While the hotspot is a little narrower compared to the P-series at distance, it isn't much more intense than that of the P10C2. Instead, EagleTac has designed the reflector to provide a beam profile which has brighter and wider spill beam. This is especially useful for duty in indoor environments because the spill beam from this light easily illuminates a room from ceiling to floor at a distance as close at 3m. Take a look at the gallery below from a side-by-side spill shot comparison of the P and T-series lights. Both hotspot and spill beam are smooth with no major artifacts other than the slight dark ring around the hotspot. This is common among most XR-E based lights. However the dark ring here isn't as bad as I've seen in some others. Right outside the hotspot is a medium sized corona which transitions into the spill beam. My sample of the T10L has a very nice neutral white color temperature, perhaps slightly warmer on Lo level. No worries of getting a blue/violet hue at high output levels thanks to the well-designed and effective heat sinking in the head. Thanks to the larger head, thermal management is also better and provides a marginal performance improvement over the P10C2.

Batteries: For batteries, this light is approved by the manufacturer for use with one 18650.

To change out the batteries: unscrew the tailcap, drop out the old cells, place in new cells observing proper polarity. Reattach the tailcap and you're ready to go.

Accessories: Several accessories are included with the light. Inside the package you will find one Elastic nylon holster, one Wrist strap, one Spare rubber switch cap and two Spare rubber o-ringsr.

Picky Little Things:Nohing to report

Conclusions:The Good - Fit and finish is excellent with nice touches such as the stainless steel bezel and scalloped tail cap. Very bright on Hi level for a pocket-sized light. Simple user interface with nice variation of Hi and Lo brightness levels. Good regulation and runtime. The Bad - Nothing significant. The Relative - Neutral white beam color tint. Very wide spill beam. Uses a forward push button. Is able to tail stand. Convenient detachable clip.
