Looks like Setapong is shipping new “flat top” versions of the DHS and P7 heatsinks. This facilitates mounting XM-L or XP-G stars (PCB-mounted LED’s) on there.

Bear in mind that unlike Seoul LEDs, Cree LEDs have an electrically isolated thermal solder point. Therefore there is absolutely no reason past looks to use an anodized heatsink, so the bare aluminum ones will be fine.
people have been talking about these mounted LEDs they get from illum.supply:

we’ve got XP-G’s on stars, XM-L on stars, you name it. Shipping seems to be $5. The XM-L’s are great and all, $9 isn’t too crazy, but what’s really caught my eye is the high-CRI XP-G they’ve got their hands on… 3000k is very warm, but my current EDC flashlight w/ the backup dropin in it (since I’m too lazy to fix the good one) is pretty cold. I was just finishing up mowing part of the lawn this evening as it got dark and pulled out my flashlight… my flashlight made it harder to tell if the grass was cut. I was literally better off not using the flashlight. After I was done I used the flashlight to shine around and check for bad spots (after all I was mowing in the dark). The low CRI really is something to think about.
Based on the bin code (Q2), I think at 1.4A you’re looking at something like a minimum of 278Lumens @ the LED… that’s very, very close to being the same as my “Good” Q5 dropin driven @ 1.4A, and it may be the same. (Cree’s XR-E datasheet does not cover the curve above 1.0A since that’s out of spec.) Anyway almost the same output numbers, but at 90+ CRI… mmmmmm.
All these developments are food for thought. Probably food for eating up my wallet. I think I’m done playing with XR-E lights now probably… for a few bucks I can make much brighter stuff.
