Looks like the same reflector to me.

I recycled the two magnets from a trashed cheap headset someone threw away. They grip hard. Just keep the RPM low or it may come out. We also use a triangle shaped piece from flat stock we cut on a band saw that cannot fly out of a 3 jaw chuck and a X shaped for 4 jaw chuck.

Manual Machinists are harder to find today and pay more most of the time. CNC machinists today are becoming more like operators, button pushers and part changers. I started manual machining for many years before slowly doing both.

You never know whats around the corner, maybe you will. But if not, be the best at what you do now, smile and be happy Big Smile


I was going to ask if they spun out on higher RPMS…I usually would use a parallel as a back stop, set the part and tap it out…
nice work!

Is the donut hole only visible when white wall hunting?

Sorry for the late reply. I took it out for a walk last night and yes it was actually big at longer distance.
.
Also noticed it was quite a bit HEAVY. So i weighted it at…..

There’s no good way to eliminate the hole other than LED swap.
To eliminate it you can:

  • dc-fix it
  • find OP reflector
  • (?) mount the LED out of focus

Each will significantly reduce throw.
Different LED is what I would suggest…

I have a XHP70.2 P2-1A 4292LM 6000K on order from FastTech to swap for the competition and maybe slice and dice. Shocked
That is the best I can do for now. Maybe the donut will shrink some.
Thank You Thumbs Up

The XHP70.2 is was shipped from FastTech ( China ) Dec 27 2019, not sure it made it out before the China New Year celebration.. Facepalm
Also ordered some testing equipment that has not arrived yet. I wanted to get some numbers for comparison between stock and mod, so it can be put back to factory quickly get numbers, then start chopping again. Big Smile

If was actually shipped on that date I think it should be okay

I really like that nice SS bezel. It is much more prominent than the original one. The MT07 Buffalo should be designed like this. Cool

Good idea to fit one of the biggest reflectors around for an awesome XHP70 thrower. Crazy

OK, we are finished after waiting for the XHP70.2 to arrive from China and within 2 days we are done modding this light.
Here are the numbers before and after the mod. Sorry no lumen numbers.
.
Stock Buffalo
132,000cd x 727m throw 5000 lumens ( claimed )
.
New 86.2D x 84.7L Smooth reflector and XHP70.2 P2-1A led ( dedomed )
324,671cd x 1139m throw , 4910 lumens ( edited : after setting up lumen tube with calibration lights correctly )
.
I am very pleased with this mod, the doughnut hole disappeared after the dedome, and the tint is perfect. I will post pics when the weather improves. It feels like a Bison now Evil
We took our dog for a walk at night to get some beam shots. I ran it on turbo a long time and it just got a little warm, I’m impressed the copper heat sink performed better than expected. It has approx 5/8 inch copper and aluminum under the led.
.
I have enjoyed this first entry to compete here at BLF. I have made new friends, shared and received information, gifts, friendship, and fellowship. Thank You Old Lumens and those with him for starting this forum. Thumbs Up

.
The stock XHP70 after dedome, I was afraid to dice because the wires were difficult to see.
.

.
The new XHP70.2.
.

.
The new XHP70.2 after my first Slice and Dice, again I stayed away from the wires.

I was given/donated a 6” Lumen Tube by BLF member manxbuggy1, Thank You very much LOL .

The doughnut hole vanished after dedome / slice and dice Thumbs Up

Thanks guys, I really like the finished light. It was a lot of planning and uncertainty in the beginning. Drawing it up by taking dimensions from the Buffalo body and the new reflector and laying them together, provided the final dimensions and the go-ahead to start machining. I read and asked many questions during the past year in preparation for this one. It was actually the first finished mod for me. It has been fun entering the competition. The other guys are the real modders here at BLF, I’m just a newbie who is still learning the basics. Thumbs Up

Looks great! Thumbs Up

Nice throw and a defined hotspot without that ugly yellow corona. Good job with the slice and dice, the XHP70.2 looks very neat!

Nice mod CNCmod! Glad the new sliced LED got rid of the donut hole – that would’ve driven me crazy.

I’d rather use my flashlight around the house than turn on the lights.

That’s a pretty respectable beam. Nice job on that bezel adapter design btw.

Just stumbled across this thread and as your username suggests, that’s some really amazing CNC works right there. Beer

Was thinking about using SBT90.2 to fix the donut hole issue while remaining similar performance.

I am working on another light using another 86mm reflector with a 90.2 running at 18amps. Wink
