SF M600 Ultra or Insight WMX200?

Hi,

I would like some help choosing between these lights to add to my collections.
One, is the Surefire M600 Ultra and the other is the Insight WMX200.

It seems that Insight lights is not that popular among here. Is this a good light or not?

Need your opinions. My budget does not matter. Just need a good rugged weapon light.

I even read somewhere that the Insight WMX200s are the standard issue lights for the military.

In all your threads regarding Insight lights basically no one has had any experience with them that they could share. Likewise, no one could corroborate that claim that the military issues Insight. In a community of enthusiasts that spans the globe, includes many LEOs and armed service members, and cumulatively has tried virtually every light in production, that should tell you everything you need to know. If money is no object as you claim, and you were actually going to weapon mount one, once again the choice is clear.
