XHP 70.2 "scraping the phosphor off the edges of the die"?

I saw this in a thread somewhere. They dedomed the XHP 70.2, but also said that “scraping the extra phosphor off the edges of the die” removed the ugly green tint in the spill. Does anyone have experience with this? Should it still be dedomed for acceptable tint?

I sliced the dome off the 50.2 in my Astrolux FT03 and it did leave a yellow/green tint around the hot spot so I sliced the sides of the dome down to the die and peeled them off. That helped some but there is still some of the green. I could probably trim it a little more if I wanted to but it’s good enough for me. The phosphor sticks to the silicone better than it does to the die so I didn’t really have to scrape anything, just peel it off. Be careful not to peel the silicone over the die itself because the phosphor will come with it and you will be left with a blue led. Don’t try to take the whole dome off in one slice, it will tend to tear rather than cut. Take it down in layers and it will work better. Also that will give you a chance to get a feel for how it cuts.

Of course you have to slice it first.

Lol, I am on my phone. One more thing, make sure everything is very clean. A little bit of dirt on the silicone will get really hot and start to burn it. Once it starts to burn it will spread and destroy the whole surface. Look at post number 51 in the thread I linked to.
