New Build/Mod. Can A Humble Defiant 3C Trounce The Mighty TN31?

In life you are molded into the person you are by surroundings, circumstances and the people you mix with.

I am dedicating this build to a very special person in my life, that my family and l have been fortunate enough to have had in our lives, who has helped mold me into the person I am now.

Peter. Your a champion in more ways than one and may this illness you have be a minor set back in your life. Get well soon.

 

Note to oneself. If you ever, ever screw together two polished pieces of threaded aluminium again you will be shot. AAAAAHHHHHH.

Ok, I have that out of my system now on with the build. Can a humble Defiant 3C out shine the mighty TN31? The simple answer is no. What about a modded 3C? I dont know. Unless I can talk Suncoaster into another trip down south or I get up north we wont know. Using Suncoasters TN31 in the backyard blew me away. This modded 3C blows me away. Hmm. I wont call it until a direct comparison can be made.

Whats it take to turn this amazing stock light into a force to be reckoned with? Firstly it takes a light in the first place. To the members who responded to my call of desperation I thank you. Needless to say the postage cost more than the $20.00 purchase price.

On with the build. I will let the pictures do most of the talking. The only parts left stock on this light are the reflector, bezel and reflector housing.

Lets start with the pill and move down. Copper pill with a lot more mass than the standard ally pill.

 
 
 
An XM-L2 U2 1C tint led on a copper heatsink lapped to the pill with AS5 between the two. Driver is a IOS 3 mode 5 amp with an operating voltage range from 3 to 18 volts. 
 
 
 
The heatsink for the pill is massive against the stock part. The diameter of the fins are 60mm with a width of 2.5mm. On a half hour run in still air maximum temperature reached was 43.3 degrees C with the light on high. Ambient temperature was 22 degrees C.
 
 
 
The fuel tank of this beast is filled with one, two, three, or four 26650's. In a pinch 4 C cells will run the light on low and medium with three battery tubes installed.
 
 
 
 
The tailcap is huge like the rest of the light.
 
 
This is the nut that holds the switch in.
 
 
 
The spring on the switch is hopeless. I have yet to find suitable springs that dont compress with the weight of four 26650. When they are found the light will have a spring on the driver end as well. The cap screws are 3mm stainless steel.
 
 
 
When you put all these parts together you have a mess.
 
 
And when you add some more parts in you have a bigger mess. The lens is one of Phils who was selling these on the forum.
 
 
 
The light in its different forms. The large tailcap does not make a good cigar grip. A lot off droop happens when trying. The other lights are there for a size comparison. To the left is a stock HD2010 and to the right is a Trustfire TR-3T6. One battery form.
 
 
Two battery form
 
 
Three battery form.
 
 
 
And finally four battery form
 
 
Thanks to my eldest son for being my Flashlight model today. He comes cheap.
 
 
 
I hope your not sick off pictures yet as the all important night shots are next. 
 
Mouse out is a strong standard HD2010. Mouse over is the modded 3C. To my eyes the 3C is about twice as bright as the stock HD2010 in use.
 
 
 
Stock HD2010 left. 3C right. The spill on the 3C wipes out what spill the HD2010 has. The hot spot is also considerably larger.
 
 
 
 
 
Mouse out stock HD2010. Mouse over 3C. The difference is night and day.
 
 
 
The tree in the back ground is about 120 meters away. Its not quite what you see but it gives a good representation of the difference in the light outputs.
 
Stock HD2010.
 
 
5 amp HD2010. Its the two x 26650 HD2010 I built awhile ago. Soon to be modded yet again.
 
 
And finally the beast. Modded 3C at 1.39 amps at the tailcap with four 26650 batteries.
 
 
Mouse out, 5 amp HD2010. Mouse over modded 3C.
 
 
Tailcap readings running four x 26650's are low .09 amps, med .33 amps and high 1.39 amps.
 
It has been used for awhile now and has not missed a beat. It throws like crazy out in the bush. Going of Google earth measurements, nah, you would not believe me if I told you so l'll leave it there Smile. To say I'm rapped with this light would be an understatement. How about it Suncoaster. You game?
 
The balance point is 50mm from the fins with four batteries. That is about half my hand width which will be why it's so easy to carry.


Thanks to some members here I've used white king to strip parts of the reflector housing and bezel. While l was at it I've reprofiled the cooling fins with a 5mm taper from one end to the other. I reckon it looks a lot better by getting rid of the square heavy look.

 
 
I got another 3C in the mail tonight from a very generous member here so thought I'd add a picture off the standard light with the modded light.

I honestly would no longer call that a Defiant 3C as there is like only 1% of the original left, lol.

Excellent workmanship! I really love the knurling.   Nice to see you finished modding that 3C light, (for now).   I would say that is a massive heat sink. Time to put an SST-90 in it and go for 12 amps or so.

Nice Light, you clearly have Talent for it. TN31’s have a MUCH smaller hotspot than yours, so if yours throws anywhere near as far, it will be a much more usable Thrower.
Cheers and Well Done.

So I've been sitting here for 5 minutes trying to come up with a response to seeing this amazing work...I'm at a loss for words.

How long did this take you?

Eh, would you believe it shone to New Zealand. But seriously Chief, that is one serious mod. Wow! About as different from what I do as is possible. Can’t touch that!

+1 It’s amazing what a talented individual with will power can do. That is a work of art and hard-core kick assery perfectly merged.

You definitely need to take off the black ano on the head and leave the whole light silver!

Oh and after that sell it to me.

Awesome machine work! I gots to get me a lathe.

Handheld spotlight, for sure. Well done!

Great build, it's a beauty! It looks best with all four tubes B-).  I also think you should take off the ano of the head. I am curious about the numbers, what does it put out and what is the throw?

Very Impressive! Interesting you get 5.6A to the LED (tailcap * 4) out of an IOS 5 amp driver, but I think I got well over the rated amps from the 7 LED IOS driver too, with 3 26650's. Amazing what a lathe and lots of skill can do! Great Job!!

It would be great to get some measured #'s from it, if possible. With all that copper and heat sinking, you should be able to well over 6 amps - 8 amps sounds good at 2 amps/battery, but proably wouldn't benefit all that much.

Sure. Send it up :bigsmile:

I never imagined it would be so large.
How much does it weigh, fully loaded ?

Fantastic machine work, DNF! I really like how you do your tailcaps.
The stock 2010 must be putting out at least 500L OTF (depending on draw at the tail). I reckon this ‘little’ ditty has to be doing 2.5 times that, easily. That thing’s a beast!

I’m not sure how long. Its been an ongoing project for about six weeks doing bits and pieces here and there. I’ve just got to work out the springs and it will be done.

Thanks to you all for the kind words.

With 4 batteries installed the center of gravity is just behind the heat sink. With your thumb and first finger snug up against the heat sink the light is pretty effortless to carry. I will have to take a picture.

I had not thought about removing the ano from the head. I may have to do that. Does anyone know what the equivalent off greased lightning is in Australia? As far as measurements go its a field I have not ventured into. I have intentionally not given any distance measurements to stay away from any controversy. Smile

Thanks mate. l’ll send it up on QLD rail. Everyone here is still in bed so I cant find the kitchen scales. Standing on the bathroom scales with and without the light the difference is 1.1kg which would be about 2.41 pound. If this is not close, when I find the kitchen scales I will amend this. I’m not sure how much I had built when you were here but it sorta just slowly evolved.

Hi Mr jacktheclipper I was tossing up whether to ask you if you could make me one of your famous lanyards for this light but in some sort of handle format. I could make an eyelet to go on the tailcap and put a noose over the head of the light. I’m not very creative so I dont know. What do you think?

Greased lightning is basically a sodium hydroxide solution (aka lye, drain cleaner). I use drain cleaner for stripping anodization.

I use the crystalline version of drain cleaner. The only parts that I have done are fairly small. I cover the bottom of a 24 oz drinking cup with about 1/4” of lye and fill the cup with COLD water. Stir to dissolve (be careful to not splash it on sensitive parts of your house or body). Cold water is important since it releases a lot of heat when it dissolves. Hot water can cause it to splatter.

I suspend the part to be treated in the cup using a couple of largeish zip ties. One is full length, the other is a piece cut off of one and slid into the head of the long one. They are arranged in an inverted T shape. Jiggle the part every few minutes. It takes around an hour to strip most parts.

Well now . That light just has to be fairly heavy , so a paracord handle would need to be fairly wide to be comfortable . It would be nice to know which battery configuration would be the most used if the lanyard was to be attached to the tailcap . If the lanyard /handle was made to noose over both ends , however , the light could be used in any configuration and the padded section of the lanyard would be at the point of balance ...

Let me think about it some more when I haven't had several beers tomorrow .
