I removed a P7 from the sink by carefully prying the legs off the board with an iron and a small blade then I heated up the sink using a gas torch until the LED could be pried off. Im not sure if this is a good technique or not but it worked for me.

I remove my Seouls the same way... with heat. Crees are easier, no legs to disconnect.

Just take a torch and heat from behind the LED will fall off.

Yes use a torch.
Just becareful with the heat i was heating up a pill to solder with small gas torch, but forgot to remove the star. Almost destroy the LED. :banghead:

The Emitter doesnt fall that easily even when placed up side down and heated, so you have to push it a little with tweezer.

this is what happened to mine.

lay somethign down for the led to land on and hold the star vertically. Heating the back with a torch while tapping. I've removed about 5 so far with no issues.

Re mounting is a different story. I've mounted 3 and managed to cook one.

These were all cree

Today I tried to solder the R2 emitter on a MCPCB with normal 25w soldering iron.
Too much heat made this. :hairpull: But it still work well.
Why shoppe do not sell high flux bin emitter on MCPCB. :scowl:

I think you can remove the emitter from MCPCB with temperature regulated soldering iron.

You say that still works well? It looks baked. Where the lens is separating.

Interesting thing is the one i killed reflowing it doesn't show any real signs of being hot.
