More info

This sink is CNC Machined from copper which is a much better conductor of heat than aluminum, and also takes longer to saturate than other materials giving you a longer span of time to run your super lights before the point of over heating.

This sink is used to build Adventure Sports own ASX70.    16mm MCPCB fit the pedestal
(not included).   For use with XHP-70 20mm boards that have been machined down to 16mm size are available.

LEDs can be epoxied to the sink using 2 part thermal epoxy such as Arctic Alumina, or reflow soldered directly to the post if using a copper direct thermal path mcpcb.   Reflowing is the preferred method if using a high powered emitter such as XHP50/70 or MTG2.

This is a DIY (do it yourself) part.   You must know what your are doing to use this part, including but not limited to electrical and thermal knowledge of LED emitters and soldering ability.

If you need assistance videos on the subject are available on the youtube channel.  More are also being added.

Have the 10amp driver, XHP70 and board in a 6 D cell Maglite. With two 26650s pumping, this slowly gets hot, but not bad. Measure 5.1 amps at the tail cap. Reflow soldered the LED board and blob soldered the driver. Used an aluminum spacer under the heatsink to get better contact with the heating element while reflow soldering the LED board since it has a lip for the driver.
