Cree MC-E Emitter in Aleph III

[Hockeymoose]

Hi Folks,

is it possible to build such a new LED (Cree Multichip emitter MCE4WT-A2-WG-M0) into an existing Light engine of my good old Alpeh III?
Do I have to make modifications to the reflector or the light engine?

I would appreciate your help.

THX, Moose
