I guess you lucked out with polarity isolation on the emitters as I don't see the postive corners clipped off.

Thick layer of epoxy??

We need to find a super cool name for this awesome photon projector Cree - ation. How about "The Illuminator" , MY 10 CREES MAKITA LIGHT just does not do it justice. Awesome, Awesome, Awesome light.

How about calling it the BFG 10000
Reminds me of the gun out of Doom
What a beast!!

How about something with "Deca" in the name to pay homage to the 10 emitters? Maybe Decamakita (too hard to say?) or Decalux, or Makita Declux (sounds like deluxe) or Makita Decree (maybe my favorite).
Anyway, sweet light. That's something you can really be proud to show off!

If not a thick layer of AA Epoxy a s Soffiler suggested maybe he filed off the under side of the emitters positive?

He'd have to file off positive AND negative on 8 of them. They are in series so the ones in the middle of the string are "floating" at a voltage that's neither full input(+) nor ground.
Speaking as a mechanical engineer and a mediocre machinist myself, I am VERY impressed with the workmanship for a homebuilt.

bombelman said:Explain please ?
The 10 Crees are arranged as two parallel strings of five in series. A series connection means: (+) from the driver (battery, this is direct-drive) goes to the (+) on the first LED of the series, then from its (-) to the (+) of the second LED, from it's (-) to the (+) of the third LED, and so on...
Here's another way to explain it. Assume 17.5V from the battery and 3.5Vf for each LED. First one in the series string is running from 17.5V to 14.0V, second is running from 14.0V to 10.5V, third is running from 10.5V to 7.0V, fourth is running from 7.0V to 3.5V, and finally the fifth in the string is running from 3.5V to 0V. So you see, of the five positive pads and five negative pads underneath each of the five Crees in one series string, exactly one of those pads matches the voltage of the heat sink: the negative pad of the fifth in series. So if he did file off the pads, he would have to file both the postive and the negative on eight of the ten LED's. Two of them have to have just the positive filed off.
Gee, that's harder to explain than I thought it was going to be.
I still like my thick-epoxy theory.

Beautiful! I love the wood and metal look. Very nice. Makes me want to skip my other projects and do my cree spotlight first. I only wish I had nice materials like that to build mine. Yours is ultimate flood, mine will be ultimate throw.

BFG would be a fitting name.
Perhaps the brightest LED-based flashlight on the planet? Great job!
The poor Surefire U2.....can't even tell it was even turned on.....:laughing:

I just dremel the bottom positive and negative off, I like the cree got more heat sink and more place to solder, and it don't get short out when I put the refector on it.cmacclel said:Nice pics
