OH - one other tip - before you try to unscrew the head, run the light on high until HOT!
Mine came yesterday and the first thing I could think was why I didn't buy more for $7.49........................
I like your new pattern and will have to do that mod after I get done with the snowblower.
Thanks, it is very easy, just be patient putting it back together. Tweezers help place the wires in the reflector.
btw, we live within ~50 miles of each other
one other note - reflector polishing
very fine steel wool, then JB Bore Brite on cotton w/ electric drill (turtle wax automotive polishing compound is a good substitute), then 'mother's aluminum polish, then BBs, then cleaned w/ acetone.
For the reflector I have all kinds of automotive detailing compounds and polish's so thats no problem.
How did you do the BB's????????
Just a bunch in a bag with the reflector ????????
You near Syracuse?
yup, right on the city line w/ dewitt
First I wrapped it in tape (to protect threads and from glue), then put a dollop of hot glue on the back and stuck it to the inside bottom of a jar. Pour in BBs, screw on lid and shake hard. If you want more texture put a hole in the lid, hold it with lid down and blast air in the hole from compressor.
I just wanted a light texture on this one, since it is already plenty floody.
Incidentally, this also work hardens the aluminum a little bit, which is nice because it is so soft. I do bigger stuff in my blast cabinet but that's overkill for anything this size...
Thanks for doing this, now I know how to disassemble mine to do something about the spotty beam. I'm probably just going to apply some frosted tape to act as diffusing film.
Yes, thank you from me too dthrckt, very useful stuff. One thread I'll keep bookmarked for a good while. Got the drivers link in soytnly's Sipik thread too 
very welcome.
you could try the tape right over the existing optic - but if you remove it you'll need a lens to put the tape on.
how about a few more links:)
both lenses are too big but barely (20.5 should be about perfect).

this is the oring pictured in the head, could be a hair larger inner dia., but good enough 4 me

also - on utilitech AA I get 2.2A at the tail!!!! That will wipe that battery so fast lol but that's OK w/ me!
EDIT: it is finally dark, at least inside - this thing makes an AWESOME light clipped to a hat - one more click in the angle would be nice, but it is great anyway. Doing this I discovered something strange - pwm is MUCH more audible (only on low) when clipped to my black hat?
You should try to put the magnet on something made of thin metal while the light is in low mode. Talk about loud PWM noise...
wow you're right - don't know why though?!
I might go w/ no lens at all so that heat can escape, and just find a bottle cap or something to cover it in my pocket.
added a pic of tailcap
stock, from top of spring to threads I measured 1.4 ohms
pulled the spring, stripped the inside of the tailcap (I think it is paint) with oven cleaner, wrapped copper braid on top of spring then around bottom coil and replaced it.
now it measures 0.4 ohms.
Insignificant increase in lux readings, but I bet AA batteries last longer.
You might not want to do this if you'll use 14500s because it might be direct drive on high (1.5 to 2A, depending on cell I tried).
Mine don't need thin metal to whine when I put them on low. :) And it's loud enough to be heard from 1 meter away. 
I love the design of this thing, was eyeing Fenix original at first, but for the money and battery life and lumens that it can push out the front it was waaay too expensive, I found the same clone on ebay little below 9$, search for "angle led flashlight". I think Im gonna buy one myself soonish and then come back for more info about modding its lens for better throw :D
Note that first result, if you use "worldwide" filter will be from ebay uk 2xAA tripple led flashlight, looks tempting but its probably with lots of flood and cold blue light with probably no modes, at least nothing mentioned in description.
Mine is super loud on low, too. Glad it’s not just mine. 
you might be surprised by how much it throws stock, but it could be improved w/ lens. I'll try my aspheric lenses again at some point and post lux readings.
Really interesting thread. :)
I am pretty sure it is. I was doing some maintenance work on a bike today and this was the light I grabbed for no particular reason at all. As always, if a light will take li-ions, that's what I'm going to use. So I attach the light to a steel beam and get to work. I haven't even taken the gas tank off when I notice the beam is turning into a familiar angry blue. Then it starts flickering, goes off and before I can get to it, comes back on. The whole thing was over in less than 30 seconds but I'm sure the phosphorus layer didn't like it too much. When I switched it off, the head was too hot to touch.
The battery (a protected TF 14500 "flame" battery) looks fine and measured exactly 4.0v when I pulled it out. Total runtime before today must have been 15 minutes or less (ie. both the light and the battery were practically new). When I briefly put it back in, the light pulled 2.1A. Well, yeah, not good if you care about durability. Like I said, the battery looks okay but the light has now been relegated to NiMH-only duty.
good idea in stock form. it is too hard on alkys for them to give much run time.
when I was taking beamshots the thing got so hot I couldn't believe it.
I considered adding some mass to the head but i don't think it is worth the time. If you need more light, use something bigger, or use two :)
It is the handiest automotive work light I've used...
Just in case anyone's interested, here's a blue version: http://www.ebay.co.uk/itm/190555132551?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Hello everyone,
I know this is an old thread, but is there any chance to have the images up again?
Thank you
