This is perhaps the right place to show my very own reflow video, it is actually the second led reflow I have ever done 
. I hardly dare to show this shaky performance (I'm is not always this bad) but I show it anyway because I like to demonstrate the set-up (and it will probably be fun to see someone else being clumsy 
).
The 'hotplate' is made of a 12V/30W soldering iron that was originally fitted with a car-plug (brand name is Toolcraft, it is a house brand of electronics webshop Conrad, the germans among us will know the shop) . I replaced the plug with two banana-plugs so that the power can be regulated with a lab power supply, and I attached a block of aluminium to the iron (see drawing). I originally made it for heating small laboratory glassware, but never used it like that, and now it has a new life as a reflow-station :
It has no temperature feed-back or anything so I found out by trial and error that when I run it at 10V (let the temperature settle for half an hour) it is hot enough to melt solder, at 8V solder is not melting yet.
The video shows the removal of the XPG-led off the mcpcb (of my Maratac copper AAA), the removal of a Nichia219 of a Ill.Supply board (that is too thick for the Maratac) and reflowing it on the Maratac board. No solder needed adding because there was enough present on the led and the board. Please turn off the sound to avoid listening to the occasional swearing 
:
I was really too shaky to do it well, but after turning off the camera I managed to put the board back on the heater and center the led really well. The temperature shocks that the led experienced were of course nowhere near the recommended Cree (or Nichia) specs, but the led works perfect as far as I can see. And here it is in the flashlight, happy with it, it is nice with an alkaline, but on a 10400 IMR it draws 1.15A 
, the beam has even improved with the Nichia in it, with a super amount of beautiful light:
