So I had to take some parts from this light for someone's build so decided to rebuild it into a pen pointer for myself. It is a Hugsby XP2 and originally was a 120Lm 2x AAA flashlight which worked well but I needed a switch out of it and tore it apart. Well yesterday I put it back together but it was a real PITA.

For anyone interested in a mod or build of one of these be prepared for a headache getting the head apart. I desoldered the factory driver and looked inside, it had a solid shelf and I could not figure out forever how to get it apart. FINALLY I heated it like mad with a butane torch and wore gloves to use two pair of vice grips and broke it apart. The threads are below the knurling on the head assembly but it has some sort of paste or epoxy on them holding them together, and I've not been able to take one apart without damaging the anodizing.. maybe if I had some rubber to put on my vicegrips.

Oh by the way, I'm actually running the LED boost driver on this diode, it put a clean 380mA out off of 2x AAA and powered my LPC-826 up over 200mw with a G2 lens. All I did was replace the leads with my own wire and tested it on a test load, then I hooked it up since I had plenty of 826 to try it on... worked fine no issues so far. Its perfectly fine to run on 2x AAA but I haven't tried it on the 1x AAA body I have yet, nor with a single 10440 but soon I will.

Duty cycle is practically unlimited, i thermal pasted the module into the head of the flashlight to allow it to transfer heat out. It runs a set of AAA dead within 15 minutes though, and the driver will get up to around 120* F over that amount of time.

It's not a review just sharing that it is possible to build in these, but unless you have patience it's not for everyone. You cannot use whole modules unless you modify the head (by milling out the LED plate deck). Will try to add more pics of the build later. THanks.

I think I found my new EDC pointer

Hey Z, nice looking little red EDC pen! :cool:
Those Chinese sure do love to use "forever" glue on everything. Glad to hear that it's running ok on that boost driver.

Thanks guys, and I wish they wouldn't use that crap on threads I'd prefer to be able to open my unit. I wonder if that's what they use to hold their homes together?!

And your right Lifetime, donate one to the cause!

Nice pen:) I just built a few pens with those diodes that I intend to put up for sale. Be very careful with the voltage increases to it as it can make a dramatic difference in output and blow on you (trust me on this one, I've blown a lot of them.
If you don't have a variable DC power supply I would first take a 10440 that is down in voltage to maybe 3.6V and see what your output is there before going any higher. It's why a lot of my builds with those involve AAA sized LiFePO4 cells rather than 10440. Going up to either a single fully charged 10440 or 2 of them raises the voltage too high and the output spikes and they blow.

Yeah all my boost drivers are very sensitive to voltage anyway. I've been using 1 primary and 1 lithium on m-type because 2 lithium is to much.

On these LPC I use primaries only they provide plenty with the boost and runtime is 15 minutes which not to bad

We think alike!

Those hugsby make nice lasers but they are a lot of work, I had done one a while back with an oclaro and the original hugsby driver, it was awsome with a tripple aaa but when I accidentally put in a 10440 it was twice as bright for 5 seconds then led, anyway I drilled out that solid lip inside and then thermal epoxied the module in, I think mine was the smaller shorter hugsby than yours, also the clicky switches arnt very tough and tend to come loose, but nice build great host, I have a very special build im working on it will surly impress.

Thanks Rich and cool build Billy i always am impressed by your builds bud! I used the XP-2 and yours seem to be XP-1 they're great little EDC lights for a pocket also, once I burn out the LEDs I will use them for lasers. Let's see what ya got billy.

Really appreciate you RICH! Let me know if you need something from me anytime bud!
