A peel washer would be handy for slicing domes off too.
Nice and clean there, Lexel Thumbs Up

It looks nice. But, how can it be as good as XPL?

I mean from the surface smoothness they are even better than XPL HIs

I can do this with all LEDs

one thing with bond wires is the fine tuning

Firts attempts look like this

Sliced and then sanded/polished down with 1500 or finer with a washer as a guide to maintain width/flatness.

The silicone surface needs to be cleaned thoroughly and little bit of debris, when the emitter heats up will burn the silicone.

Wow that looks pretty tidy.

As everyone else seems to be guessing the technique, I’m going guess microtome

Good tip Lexel, might try it myself sometime.
Do you think it will work on XPL2 HD? It should outperform XPL-hi in my opinion

Razor blade is the first step
I used a thicker washer for it as first step

Then a 2. 0.1mm thinner washer for the 1500grit paper

3. Washer 0.1mm thinner
start with 2500 grit
used 5000 then
last a very old used 5000 one

I have done this long time ago with XHP70, and used only 1000 grit sandpaper to leave the surface little bit muddy and claen everything with isopropyl alcohol. Results are amazing in terms of throw and beam looks phenomenal.
Only downside is lumens lost up to 20%…

Great work Lexel !

Ok, i just tried it with XPL2 HD, i can confirm, it is harder then it looks.

You really have to have the good size shim and it would be nice if you have it from alu or another hard material, since the plastic convoy butterfly spacer which i used is too soft.

I (accidently) cut off the rim of the spacer and ended up quite low, but i managed to get a nice and clean cut. (Don’t know if there is any material left to sand it down to get it even flatter)
Do i see a bondwire over there ?

The result is good, but not what i hoped for, throw improved but it still shows the ugly yellow/greenish corona

Have to compare it with fresh charged cells against a XPL-HI to get real world results and see if it outthrows XPL-Hi

You need to remove all phosphor around the die to get rid of the yellow corona.

That would turn it into a blue corona and reduce the lumen output.

You can keep a tiny layer, but practically speaking removing most of it will imrpove the beam quality.

Maybe cutting it away at an edge, say 45 degrees, makes for the best beam? Nice work Yokiami!
