Princeton tech switchback mods?

[shuttlefever]

Hello all,
I am a newbie to this site but so far it looks like a great resource! I was wondering if anyone had heard of or seen any bulb modifications done to the princeton tech switchback 2. I like the light a lot, but have heard that theres a change that can be done to them to make them quite a bit brighter. Any info is welcome!

So far I have read a post on the mtn bike forum of someone inserting seoul U-bin P4's.

I want to do this, but I'm searching for more info.

I've never modded a light, and need tips to desolder, and solder these in.

Found the emitters for about 5 apiece.

Anybody share more here?
