My personal opinion....
Having been in law enforcement for the past ten years, and having used quite a few different duty lights, I would say it depends on what you need the light to do.
If your talking about a duty light for full time night shift use, I would stay away from LED all together. Go pick up a good incan. My reasoning behind this is simple, LED still can't offer a full spectrum of light. This full spectrum is what your eyes have been used to seeing your entire life, not LED.
Try this, take two good lights, one LED and one incan, bring them outside at night and find a bush or a shrub about fifteen feet away. Using just a single, quick flash, shine the LED at the bush. Could you readily make out the different colors in the bush? How about making out an outline of something behind the bush? Now try the incan... see any difference?
For me, this test sealed the deal. In a nutshell, we depend on our eyes, and thus our lights, to keep us safe (and alive). If using an LED caused me even a little bit of a pause to make out what was in someone's hand, or see someone hiding, that lost time could prove tragic.
So anyway, for duty use, stay incan...for general use, LED is fine (and I would try the wolf eyes, love mine...)
Good luck, brother,,,,,,stay safe...
