I received this light the other day and am very happy with it! Modding potential with this thing is through the roof and the throw from it is amazing! Build quality is just average.
The threads, while plenty in number, depth of cut and of average machining, were dry and dirty and squeeled like Ned Beatty in deliverance. A little silicone grease took care of that although I still need to clean and regrease them. O-ring grooves exist at every joint but do not have o-rings installed. I was able to add my own as I have plenty in my parts kit. The lens is acrylic and the reflector is chromed plastic. Normally this would be a negative but if you look at the intended purpose of this light you can understand why at least the lens is not glass.
This light is pure fun to hold and use. Like a movie with lots of CGI and eye candy, you can excuse the lack of plot and questionable acting…it’s pure entertainment! The kids have nicknamed it “The Pimp Stick” and it’s a perfect name for it!
All pics below were taking in my family room on the floor in poor lighting using long exposures and no flash on the macros with the camera held in my shaky hands. Lots of lint and cat hair I wasn’t able to see until after I took the pics. Please excuse the mess. And now for the tear down pics (click pic for larger version)…
I got the light Saturday morning and that evening we built a campfire in the back yard to roast marshmallows. A perfect opportunity to test out my new light. WOW! An unlikely torch to be such a crazy focused thrower/light saber. Even the spill is very focused.
Here is a ceiling shot. This was taken from a distance of @ 3m (flashlight on floor with 10ft ceiling). Believe it or not, the hotspot is only roughly 4″ across!!! It looks bigger in the pic because the camera doesn’t know how to handle the difference between the hotspot and the spill. The picture doesn’t capture the whole spill which is about 4ft across.
Here is the source of the craziness – the N-F-B91 from DealExtreme.com
Please excuse the blurriness on some of these macro shots. They were long exposure pics with no flash and held by hand, not tripod. There is also a lot of lint, cat hair and a stray blonde hair in some of the pics also. They did not come with the light.
The “teeth” on the head are extremely sturdy. Triangular in profile they will not bend if you decide to mash something (a skull perhaps, car window, concrete cinder block…) with it. The crenelation on the bezel is extremely aggressive and will tear up any fleshy object with a poke and twist combo.
The battery/batteries are contained at the base of the light where the hand grip is located. The grip is rubber over the aluminum body and is quite comfortable to hold. The tsuba/lanyard ring is quite solid and machined from billet aluminum.
The hand grip unscrews from the main body to expose the driver pill. Nothing special here but there is also a spring located in the handle to assure contact for negative ground from battery in a strike situation. The positive connection at the driver is also sprung for no interuption of circuit. Soldering could be more substantial at spring base.
Here is the spring I just mentioned above. It seats on the lip inside the battery tube and presses on the negative contact ring of the driver PCB. This is why soldering is not needed between driver and pill.
Here is the coupling between the upper and lower body halves. I added all thread o-rings and grease which can be seen. They came very dry and sounded worse than nails on a chalk board before I lubed them. They are fairly well machined, if dirty, and provide a pretty solid connection between body halves. I wouldn’t worry too much about the light breaking in the middle when striking an object.
There is a lip inside the head against which the spring sits. This provides a little shock and impact protection to the emitter pill.
While the emitter pill is hollow, is is also a hair shy of 3/4″ internal diameter. A section of 3/4″ solid aluminum rod will press fit tightly into it to make a massive heat sink. This baby realy is a modder’s dream. Lots of potential here!
A 20mm star fits perfectly. This particular emitter is a Q4. Any upgrade to the emitter will require a solid core to be installed in the pill for more heatsinking. As it is, it is enough for this mildly driven Q4.
The pill is 12.20mm thick. For someone with access to a lathe, a new pill with ridiculous heatsinking ability would be a simple thing to make. Here are some measurements for those inclined to make such a thing…
The tail cap is a pretty solid chunk of aluminum. The switch sports a solid connector but is held in the tail cap with a plastic insert. This is the only component I did not take apart as it wasn’t worth the chance of ruining it.
The switch boot sits flush with the tail cap at the edges and extends out in the center. It is pretty thin rubber and not the highest quality. It should last a good while as long as you don’t strike or abraid anything with the tail of the weapon, err, uh…light.
Switch action is standard fair and not bad, really. Reverse clicky of course.
Here is the 3*AAA battery carrier it comes with. An 18650 can be substituted for the crappy 3*AAA carrier. It’s nice to have the option of a more readily available battery alternative if needed though.
