Salvaged MC-E LEDs acquired, now what?

I have just salvaged six bare MC-E emitters from a failed vehicle light. I know three of the emitters are still good, while the other three show no signs of damage, but have not yet been tested. I have only worked with emitters mounted on stars previously (and never with MC-E emitters) and would like some advice.

I would like to find some way to work these into either a flashlight or a battery operated work light similar to xxllmm4's ammo can light.

  1. These are bare emitters; what is the best way to mount these on a heat sink surface while isolating the leads from both the heat sink and reflector while allowing clearance for the power leads?
  2. Can anyone recommend a driver or configuration that would allow me to run these connected in series or series/parallel from a 12V gel-cell type battery?
  3. Per the flashlight-wiki article, the max current for this is 700mA. Would a single SSC P7 driver rated @ 2.8 amps be a good match for this emitter with the dies connected in parallel? The MC-E appears to be very similar in design and function to the P7.

Would be better to series connect emitters to a 700mA driver or so. Better thermal safety for multi emitter setups. I would look at having 3 emitters in series with a 700mA Buck driver that runs off 12V. "thermal runaway" is something to look up...

I was overthinking this a bit. As each package has four dies, I was thinking of 700mA/die rather than 700mA/package @ 175mA/die.

Some food for thought: Here's what I did with an old MCE that I had kicking around. It still never ceases to amaze me every time I use it.

Also some ideas for MC-E with 8*7135 driver http://www.candlepowerforums.com/vb/showthread.php?201392-Poorman-Mutli-Lux-setup-method. Each die can get as much as 0.7A.

What vehicle did you salvage them from?

They are aftermarket dozer work lights. One of the dozers had an electrical problem and burned out the driver/circuit on the board but at least half of the LEDs are still functional.

Good to know, I was about run out to the local pick and pull to spend more money.
