Lumapower d-mini mod

Hey ya'll! I'm new here so I guess this is my official introduction

Alright so I've been looking for a mega thrower that's lighter than what I'm carrying now at work (fenix tk41 - over 500g with batteries installed!). I work nights and go outside sometimes so I need a good thrower to see wild animals. On CPF there is a member who modded a Lumapower d-mini VX(not sure if its ultra) with an EZ900 1.4a r2 and it can crank out 100,000 lux @1m with the Turbo Force head!! I want to replicate this mod but I definitely need help.

I have no idea where to get an EZ900. Anyone know where I can get one?

Most of the EZ900 LEDs I've seen were scavenged from other torches. I cannot find a reliable source online yet.
