I need to lay down the backdrop to put this into context. Almost 20 years ago, I had the unique opportunity to direct a force-on-force training program for the United States Navy. I maintained this position for almost a decade. In that position I was directly involved in literally tens of thousands of simulations involving projectiles flying back and forth between organized forces.

Put this together about a year ago, it's dated and incomplete, but it will suffice.

Really haven't been playing with small lights or strobing small lights for quite some time.
Bottom line for me: I have had many, many police officers, military folks and "civilians" personally email me with their stories and their thanks for the tool.
User Know-how, user-interface, strobe rate, intensity and the situation at hand all play a factor in the outcome of any encounter.
There is is no one "right answer" or do all tool.
As an FYI: The last training session I did (about 60 days ago - First one in about 2 years) for a fugitive recovery task force (CA DOJ) was conducted in low-light. Without "selling" anything, I simply went into the darkened shoot-house using Simunitions FX and solved the same problems presented to the officers at hand.
To a person, they wanted to know where to get what I had in my hand (It happend to be a modded Gladius...go figure). Being the receiving end of proper movement and the correct application of lighting principles "sells" itself.
State your credentials, abilities and well-reasoned opinions all you want.
Nobody at this point has convinced me that I am better off without the strobe as an option in my arsenal of choices.

It's still a relatively new concept and should not be boxed in too tightly, too early.
