Yes, you are referring to the PD32 Ultimate edition. This has now been superseded by the PD35, which does 850 lumens. Both use an XML emitter, compared to the XPG in your standard PD32. There is no easy way to modify your light.
All is not what it seems though. The lights with the XML emitters cannot sustain their maximum modes for very long, typically about 3 mins. At that light level, the emitter gets very hot, the small frame of the light cannot dissipate the heat fast enough, so the light will step down in brightness to prevent overheating.
The XML lights, with the small head and relatively shallow reflector will give you a big wall of light. Your XPG PD32 will give you greater throw.
