Wow, yet another awesome rendering! Just a note/fyi to all designers, I'm pretty sure the best place for the fins is where the heat emanates from, and that's where the LED is, or at least where the shelf it sits on meets the body. That should be the best place to locate the cooling fins. I don't see that approach in these two renderings, though I'm sure I haven't seen them all. The fins on the one above are below the switch and pill cavity, relatively far away from the heat source, so it's not making an efficient use of the fins.
This isn't the first time this issue of fins placement has been brought up, but I'll keep on reminding those needing reminding. Keep in mind that the perhaps the best thermally designed production light is the TrustFire TR-J20, threads here:

Yes, butt ugly, but they got the mass and fins right for high watts usage. I've experienced the opposite extreme - a TN31 that has a narrow neck where the LED sits, and when you crank them up to 6.5A, maybe ~26 watts, boy does that neck of the light get hot.
