You used to have heatsinks for old style c-mags with the bigger inner diameter, any chance you got one of them left?
Setapong,
Can you post a picture of the top of the DHS Flat Top "C" heatsink? Is it similar to the P7 version?
Thanks!
Hello Setapong,
I have been planning to make an XR-E R2 Aspheric 2D-Mag thrower for quite some time now and I finally have all the parts in order. The only thing I don't have is the heat-sync and I wanted to order that from you. The only thing I'm not sure about is which one to get because of two things. One, the emitter is on a star (and I don't want to remove it) and two, I'm not sure about the focal length. Maybe you can tell me which one I need though if I list my build parts....
This is the URL for the light itself. It is a Gray Mag-2D Krypton (not LED).

This is the URL for the LED. It is an XR-E R2 mounted on a 20mm star.

This is the URL for the Aspheric Lens. I will be removing the reflector and paining the inside of the MagLite black.

Someone stated on Deal Extreme "It produces a sharp image of the emitter when the flat back is 28mm from the LED front." but I cannot confirm this.
Basically I'm looking to have the head of the Mag turned almost all the way down so it's screwed down almost as far as it will go. Then I wanted a little bit of room to turn it CW or CCW so that I can adjust the focus of the die based on whatever distances I'm shining the light at.
Can you please tell me which heat sync I would need to order from you and what the pros and cons are of the anodized one? IE, why wouldn't I just use the bare aluminum one?
If I absolutely have to remove the LED from the star, then I can try that, but I'd rather not have to mess with it. I plan on running the LED at either 1000ma buck, 1400ma buck, or direct drive (2000ma max on 4.2V 18650).
