CNCman's entry to the 7th annual BLF/O-L contest [mod light category]( FINISHED )

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

Only decent results I have had with that reflector is xhp35HI

Have you tried a different led yet, CNCman ?

.
The XHP70.2 is was shipped from FastTech ( China ) Dec 27 2019, not sure it made it out before the China New Year celebration… :person_facepalming:
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. :smiley:

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

“The Chinese New Year of 2020 falls on January 25th (Saturday), and the festival will last to February 8th, about 15 days in total. 2020 is a Year of the Rat according to Chinese zodiac.”

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

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

.THANK YOU :+1:
Stock reflector is on the left. Hard to believe the one on the right fit. :smiling_imp:

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 :smiling_imp:
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. :+1:

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 :laughing: .

The doughnut hole vanished after dedome / slice and dice :+1:

Nice work CNCman.Just a small improvement from the original torch. :slight_smile:
Manxbuggy 1. Now theres a name from the past. All the best to him and his brother.

Really great result. :slight_smile:
That’s what MT07.2 should have been. :slight_smile:

Ahah, I guess I should have come here before replying to you on my thread :stuck_out_tongue:
That beam is WOOOW :o

Great work :wink: Need on like that now :smiley:
Congrats on you mod!!

Wow! Superb! :beer:

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. :+1:

Looks great! :+1:

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

Great mod! :+1:

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

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

Well done on completing your build :THUMBS-UP:

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:
