Defiant 3C MT-G2, 4 x 26650 custom build. 9 Amp driver pictures added 16.8.13.

I’m jealous. You get more people reading nothing in an hour than I get in a week. :_(

well, you can always use it as a baseball bat :bigsmile:

Gees your right. 136 reads and I was still trying to get it all up. I hope you all come back. Sorry guys. Done now.

I love those dst builds you do, I can’t wait to get a chance to do some machining.

Nice! How long would the tube be if it was proportional adapted for a Shocker? :slight_smile:

Nice machine work, your copper slugs make me jealous.

Not bad

That pill :love:

I bow in the dust of your grand and magnificent creation.

I can understand what you mean by not being that amazed by the output considering all the great work put into the light. It looks like a lot of great work and though were put into this build!

Im not sure exactly how many amps you are seeing, but if its around 4A. Then its around 26,5W at the emitter (assuming 6,5v.) Which is stock SRK territory, or slightly above. (3 XM-Ls generally output more lumens than a single MT-G2 at similar high energy consumption.) Also, MT-G2 is a floody emitter by nature, its mainly meant for useful close/mid range lighting, not impressive throw.

When that is said, most lights start sweating at that kind of current, some even overheat with long continuous use. I have a feeling yours just say "is that all you got! I can do this all day, at least til the batteries are empty." And with 4 of them, it should have good run-time too. :)

:beer:

holy crap! lol.

It's crazy how fast things change in land flashlight. I remember it was just like yesterday when you made that incredible pill with a pedestal because no copper mcpcb's were available. It is still a better solution, but I imagine you would not do that way if you started today.

Yeah, the MTG2 in the DST reflector was a let down for me from throw perspective. It lights up a big area nicely and is great for general usage. I imagine dedoming will get you easily above 100kcd. How far above that is not known at this stage. It's on my list to try to find out. I know it won't compete with an xml2 in throw distance, but I like big hot spot throwers.

You're lights are so frickin amazing. I can't think of any production light that could compete with them in heat sinking and looks. It's going to be awesome when they are performing at their true potential. New emitters may need to come along to realize it, but it will be worth the wait.

I have just completed some rough and ready measurements on 3 lights at 8.6 meters. Take them as you please but it will give you a rough idea. I have no idea what the batteries were charged at but probably around 4 volts. All the drivers on the below 3 lights are identical 5 amp 3 mode IOS drivers.

HD2010 2 x 26650 98366 Lux.

3C XM-L2 T6 113158 Lux.

3C MT-G2 47334 Lux.

The beam on the 3C is like a laser beam compared to the HD2010 and the MT-G2 has a very noticeable hot spot which is around twice the size of the HD2010. So at 100 meters the MT-G2 looks like it lights up everything but loses all intensity.
Thanks to jmpaul320 for reasons known to him.

I hope you own stock in Alu production. That’s some seriously heavyweight hardware.

Wow! Amazing machine work! I bow before you great master!

Wow! Those are some really cool looking lights! I cant wait for the beamshots either. That machining is awesome.

The flashlights at the back are so tall that made me think they’re samurai swords! (or light sabers).

Very nice machine work MRsDNF. Boring something that long can be challenging to say the least. I only have a QCTP 5/8 boring bar holder and boring bars where not available in the length I needed especially when the holder eats about 3” of that, so I had to make my own using a TCMT 21.51 insert and 4140 chromoly steel rod then heat treating it. Now I can bore 10” taking small cuts, if I try to take larger cuts it begins to chatter fully extended.
I know how much time goes into making something like this and its greatly appreciated that you can share it with the rest of us. I was going to attempt something on the same lines as this with a MT-G2 but was afraid it might turn floody instead of a thrower. I would really enjoy seeing some beamshots with this setup when you get time, maybe it will help me decide what to do with my backup 3C defiant. I already modded one with a XM-L2 and a copper sinkpad with a led-lck 5 amp driver with 2 18650’s. The throw did increase by eye, but not as much as I would have liked. By the way, that’s a very nice switch design.
Keep up the good work MRsDNF and thanks for sharing your hard work. :wink:

Thanks for the kind words all.
Night shots added to the 1st post.

Thanks for posting some beamshots MRsDNf. That thing looks to be awesome. It doesn’t appear to be a great thrower but the beam is very even all the way out, no rings. The color looks good too. I have got to get me a couple of those MT-G2’s.
Thanks again. :slight_smile:

That is one serious light there! Another one of your beautiful designs. I am really jealous of how neat you are able to get the finish of your lights, love it!

Quick update. I hate to say this but the light developed an intermittent fault. One of those ones where if you whacked the head of the light hard into your hand it would work again and stop the light flickering. Some may laugh at this but l nearly cried. Yes my soldering has let me down again. Just when I think I’m getting better at it it turns around and bites you. The problem was traced to either the negative or positive strip on the star to led connection. I have since replaced the led which still works fine but thought I will put a new one on just in case. The star is starting to look decidedly second hand now with all the heat put through it. I used solder this time instead of solder paste on the led to pill/star junction. A new driver is being installed not that there was anything wrong with the old one, which will I hope boost output a little. Hopefully it will all work when I get it all back together. l’ll update when its all back together and working.
