I came across this mod posted by you on hacknmod.com and I had to track you down to ask a few questions. I'm looking to DIY this with your parts. I can't decide if I want to get the heatsink from you and put it together myself or get the drop-in mod from you.
You could also use a 3D Maglite with the 5 mode, or 3 mode driver. 3 X normal D sized NiMH batteries would be about 10,000mAh's capacity
Can this scale up in size with Li-Ion batteries as well? I have a 3D and a 6D Mag. Could I use more of the Li-Ion batteries in it or would it require custom spacers? I'm not a battery expert and I know Li-Ions are dangerous when used improperly. Should I just go find myself a 2D Mag?
Did the fiber optic plug come with the voltage monitor? If not, can you recommend a good one for a DIY?
If I'm reading your guide correctly, the machining of the cap is not required when using 32650 cells unless you're using the protected Novaes?
Would you recommend the protected over the unprotected in this thread for this build? I have a quality multimeter to test for overcharging so I'm not overly concerned about a protection circuit. I'm more concerned about accidental complete discharges but with the voltage indicator light that wouldn't be so much of an issue.

* Long run time and durability (about 4 hours on high (1000 lumens), and 11 hours on medium (350 lumens) - if using the Feilong cells)
* Not over driving the emitter, it should last a life time with normal use
* Perfect size. Not over driving it, and still very bright at 1000 lumens. Plus having 3 modes, and of course the voltage monitor.
All features add up to the perfect combination for a great 'user' light that you will reach for most often!
I will show several options for an Awesome Maglite Flashlight modification using the super efficient XM-L Cree emitter. (there is also a single battery 'Stubby' version shown below)
See below for a really nice battery voltage monitor installation!
(This is for 2 cell Li-Ion, or single cell Li-Ion, as well as 5 NiMH, and 6 NiMH)
You can use this thread as a DIY tutorial, or get the parts and/or complete light from me...
The XM-L will put out an incredible 386 lumens at 1 Amp! (compared to only about 220 lumens for a Q5) That's 75% more output for the same current!
It is 1000 lumens at 3 Amps, so I chose a 3 Amp/3 mode driver...
* Good heat management because of heatsink mass
* Voltage monitor option
* Good battery capacity vs size of light
* Heavy duty side button forward clicky for easy mode switching
* Turn the head for focusing
* And of course the nice quality finish of the Maglite with color choices
The Maglite heavy duty side button switch is a forward clicky. You can have a momentary on if desired. Or you can switch modes easily before you click it all the way on…
The driver is a 3 mode driver. High, medium, low. This one switches modes very smooth and consistently. It has memory too... So it will remember where it was last at. Great driver for this mod!
(current readings shown below)
Note: I like the 2 X 32600's (or 2 X 32650's) best for size vs capacity, but there are a couple of other combination's that would also work with this driver...
Note: Get your charger from a reputable source and make sure it comes brand new in the blue box. Otherwise it probably won't work properly. (I have tested maybe 20 of the WF-188 chargers)
After the build pictures, I have the testing, and current readings for this driver using the 2 X 32600's. I have current readings at the emitter, as well as at the tail. (battery current draw)
Switch prep:
If you would like to see more detail on the switch mod, see my Maglite P7 flashlight modification here: Easy Maglite P7 Mod! Nice...
Optional Battery voltage monitor:
The battery voltage monitor is designed for LiPo's, but Li-Ion's are the same voltage as Li-Po's, and it is a great set up! (Must use the 3.6 (or 3.7) to 4.2 (at full charge) Li-Ions. Not the 3 volt ones)
(This is for 2 cell Li-Ion, or single cell Li-Ion, as well as 5 NiMH, and 6 NiMH)
I love having this voltage monitor for my 32600's! Here's how I installed it using a fiber optic plug...
Battery voltage monitor color code:
Bright blue - Full charge
Cyan - Very good
Green - Good
Yellow/Amber - Low warning
Red - Batteries low
The Spectrum battery voltage monitor will have a short 2 second initialization and some flashing when you first turn on the light. This is normal. As seen in the video shown above...
Heatsink/driver/emitter:
The mass of my heatsink is the key to good heat management for this build. It is machined from a solid piece of 6061 round stock...
Important: The heatsink set screw fits a 1.5mm Hex wrench… If you try to remove or adjust the heatsink, be aware that it is under some spring tension. As can be seen it the picture…
Reflector:
Some slight modification needed for the reflector. (easy)
The stock reflector seems to be pretty good, but I want to test others to see if it's worth the price of the upgrade...
I also ordered some of these UCL lenses to check out: UCL lens
I'll post results after I get them delivered...
Update: I like the UCL lens best, and the reflector linked is a very nice reflector. But honestly, the stock reflector is not bad at all... But it does show some 'clover pattern' that will be removed with the MOP aluminum reflector...
Maglite Rebel reflector:
If your interested in this build using the Rebel reflector, it does offer a little tighter beam and throw...
It's quite a bit deeper than the standard reflector, and the emitter needs to be 12mm instead of 14mm.
It fits fine without the voltage monitor, but for those wanting the voltage monitor, I really don't think there is much room unless I made the heatsink thinner, and that would take away from the heat management.
About the beam, yes it does give a little improvement. It was noticeable at short distance. But not so noticeable at 75'. (not to my eye) Maybe a 6 or 7' spot vs an 8' spot with the standard reflctor.
I would imagine that at longer distances, like maybe 200', it would throw better. But I did not get out and test farther than my back yard 75' distance.
Quite honestly, I was expecting more of a difference than I was able to notice. The stock reflector is really not bad at all in my opinion.
But if you want this reflector, the LED light cost more, plus the extra work to re-size the emitter. This is done after it is glued to the smaller 12mm post with thermal adhesive so that there is not a heat issue. I use a tiny belt sander. (3/8" wide belt)
So add $25 bucks if you want this build. (but no voltage monitor option)
Beam shots:
It was a little foggy out...
Spot and spill:
At close distance, the stock reflector shows a slight 'clover pattern' around the spot, but it is not too bad at all. To eliminate this 'clover pattern', just use this aluminum reflector from KD: http://www.kaidomain.com/product/details.S004023
The spot, is about 8' wide at 75' when best focused.
Using the stock reflector, pointing at a wall, I measured the spill at 5' distance, and it is 10' wide...
Then I measured the width of the spill at 9' distance, and it is 17' or 18' wide.
Current readings: (High/medium/low)
Measured at the emitter:
* High - 3100mA's
* Medium - 948mA's
* Low - 157mA's
Measured at the tail: (battery current draw from 2 X 32650 Li-Ion's)
* High - 1575mA's... Estimated run time - About 4 hours!
* Medium - 525mA's... Estimated run time - 11 hours at about 350 lumens!
* Low - 114mA's - Estimated run time - 52 hours!
That's using 6000mAh capacity 32650's...

Hope you like it!
Sleeve for 26650's:
If you want to use 26650's instead of the 32mm batteries, then I have some perfect sized fiber glass material:
I ran both of these builds shown in this first post for 15 minutes on high to see how they held up heat wise... (2 X 32600's above, and 1 X 32650 'Stubby' below)
Both were excellent... The 'Stubby' seemed just a tad warmer in the hand. But both kept the same brightness. (comparing my P7 build side by side every few minutes)
With the 2 X 32600 3 mode set up, I even took the head off so I could remove the heatsink and feel the heat of it in my hand at the end of the 15 minutes. It was warm, but not hot. I could easily hold it without any discomfort...
I think this is good enough for me. I'll probably be sticking with these driver choices because I like having a choice of modes. (especially the 3 mode set up)
If your in a situation where you know you will need to have your light on for a long time, then just switch it to medium!
(over 11 hours on medium with 2 X 32600's at about 350 lumens!)
Here I will also show a single cell Maglite 'Stubby' modification with 2 driver choices...
On high, it is as bright as the 2 cell version above!
This makes a great sized Flashlight mod for a single cell, or a laser too!
If you wanted to make this into a laser, all you would need to do is just add the $38 dollar heatsink to the basic kit price shown below, and it would be great for a FlexDrive! (or dual FlexDrives!) The switch prep shown in this thread would also be needed for the laser mod...
The heavy duty side button switch is a forward clicky. You can have a momentary on if desired. Or you can switch modes easily before you click it all the way on…
The 5 mode driver has: High, medium, low, fast strobe, SOS.. (not necessarily in that order) The 3 mode driver has: High, medium, low. Both have memory. So they will remember what mode was last used…
Basically the same but smaller...
The single cell 'Stubby' uses a different driver than the 2D Maglite mod shown above...
Both drivers for this build, are a very quick off/on to switch modes. The good thing about them, is that they have memory. So if you like a particular mode. Such as Medium or High, then you can just leave it on that mode...
(but these two drivers work well in a 3 X NiMH configuration as well)
Note: If using a non-protected Li-Ion, just beware of the following information... The 5 mode driver specs say that it requires an input voltage range of 3.2 - 4.5 volts. So I think we're alright with this set up. (3 mode driver says 2.8 minimum, so you have to watch that you do not over discharge the Li-Ion, but it will get noticeably dimmer, and you will realize it needs charging)
Reminder: You could also use a 3D Maglite with the 5 mode, or 3 mode driver. 3 X normal D sized NiMH batteries would be about 10,000mAh's capacity!
Host modification:
Current readings for 5 mode driver: (High, medium, low)
Measured at the emitter:
* High - 2310mA's

* Low - 200mA's
Measured at the tail: (battery current draw from a single, 6000mAh 32650 Li-Ion)
* High - 2400mA's... Estimated run time - 2 1/2 hours!
* Medium - 1135mA's... Estimated run time - Over 5 hours at about 380 lumens!
* Low - 212mA's - Estimated run time - 28 hours!
Current readings for 3 mode driver: (High, medium, low)
Measured at the emitter:
* High - 2800mA's
* Medium - 850mA's
* Low - 140mA's
Measured at the tail: (battery current draw from a single, 6000mAh 32650 Li-Ion)
