If Gene builds a few warm white XPG Wildcats I will be in a similar quandary
I received 3 M61W modules on Monday and immediately popped them into a couple of SureFire 6P hosts and an MD4 with 2x18650. The tint is not quite as warm as the M30W and M60W predecessors. It is pretty much neutral, with a slight tinge of yellow-green.
The big surprise was that one of the modules has a beam pattern almost the same as the M30/M60 series!
Looks like I am going to be making some beamshots to back up this claim...
Brightness is somewhat higher than my 170 lumen warm modules, but not huge. Low beam is brighter since the XPG diode has a lower forward voltage drop than the previous model.
These are certainly worth the money.
