The head houses a glass lens, textured aluminum reflector and an XR-E emitter module. To be more precise, the emitter module is actually screwed into the battery tube.The head in coated in Type 2 anodizing which is smooth and evenly done and has a crenellated bezel. Machining is also good, no sharp edges, chips or marks. There's a hexagonal ring machined around the head which works well as an anti-roll feature. The glass lens is made of regular uncoated glass, the surface is smooth and polished however there was a small chip on the side of my sample. The reflector is also nicely finished as far as it's coating and texture are concerned. The only problem with the reflector is that the opening at it's base is too large for the XR-E emitter. The reflector drops into place and is held in place by a retaining ring which screws in. The emitter module houses an XR-E emitter mounted on a star PCB. There is a problem with it's design because if you screw the head all the way down, the metal reflector causes a short across the "+" and "-" solder points on the emitter. An attempt was made to fix this by placing a shiny, silver sheet of insulating material around the emitter. However this really didn't work well in practice. Shorts still occur when the head is fully tightened, which in turn causes random flickering. Another attempt at a cheap fix was made by placing a coil of solder around the threads of the emitter module. This is to give some spacing between the module and the battery tube to accommodate the length of a 14500 cell.

The battery tube is the part of this light which has the least problems, which is pretty disappointing really. It's a simple design with a band of diamond textured knurling for grip. There're two flat faces machined onto the knurling, one of which has a Kai Domain sticker applied. Coating and machining is smooth, similar to the head. No marks or scratches were found. The threads on the battery tube were pretty worn out though, especially the threads for the tail cap. Take a look at the image in the gallery below and you can see that the spaces between the threads have had the coating scratched of exposing the bare aluminum. There are 2 rubber o-rings on both ends of the battery tube, but these do not provide any form of water resistance. Both the head and tail cap still screw on loosely despite having the o-rings in place. The tail cap proved to be the most problematic part of this light. When I initially received this light, the switch didn't work at all, so I took it apart, made sure the individual components were cleaned and put it back together. The switch now works, but only if it was screwed on loosely, obviously this makes the electrical contact insecure and caused the light to flicker as well. If tightened all the way down, the switch will be stuck in the on position. This effectively caused the switch to work as a twist activated one. The rubber button cap protrudes out the tail so it wont be able to tail stand. The texture on the rubber cap is an aggressive dimpled texture and feels pretty good.

Additionally, be advised that the rough surface of the aluminum switch retainer slightly damaged my 14500 cell. As you can see from the image to the left, the plastic wrapping around the "-" area got torn up. The metal contact surface also suffered some scratches.

The light out put it actually pretty good. On high mode, it actually performs on par with the Fenix P2D CE's turbo mode on a 16340 cell with similar runtime too. I don't really appreciate the medium output level though, mainly because it's output level is similar to high. The beam quality on my sample is actually very good, a definite contrast to the build quality of the light itself. Beam profile is a smooth medium spot with some slight ring artifacts. Beam tint is a nice white with just a slight hint of cool blue. Lastly, the strobe mode is slower than the standard tactical strobe, more like the blinking rate on bicycle tail lights.

The operating modes are:
Off > High > Medium > Low > Strobe

The Good - Nice beam quality and bright output. Very cheap considering the number of modes available.

The Bad - Horrible build quality, especially with the switch module. Item was received in a non-functioning state.

The Relative - A good buy for modification projects, or if you're feeling lucky. Uses a reverse clicky instead or a regular clicky.
