Hey guys, just thought I'd share some knowledge with you all about the above mentioned LED's.
They can all be fully dedomed with pretty decent results. They just need a little more work that their predecessors.
Firstly they are NOT distributed phosphor. The dome is crystal clear, it's yellow appearance is due to the fact the whole emitter surface is covered in phosphor.
Slicing and dedoming does not seem to have as drastic an effect on tint as it does with previous version.
When sliced and dedomed they get a strange green halo, this is where the extra work comes in when dedoming/slicing.
To get rid of this green halo you need to take a very sharp knife or razor blade and scrape off the excess phosphor around the emitter.
There is no need to worry about damaging bond wires as they are all flip chip design so the wires are under the emitter.
I have dedomed a 50.2 with great results,
86kcd I'm a smooth C8 reflector.
Unfortunately I did this in haste and have taken no pictures.
I have a couple of XPG3's on the way so when they arrive I will do a step by step.
Hopefully this will be useful for some out there.
Thom.
