This is a very valid point. But an adequate light is a force-multiplier. That presumes enough candle power to temporarily blind or disorient a target.
Even in my own home, if something creaks too loudly at oh-two-hundred I want a nice, bright, tail-switch activated, momentary-on light with me. It may or may not be a target I want to shoot. I need to absolutely, positively confirm that before I pull a trigger.
And the shadowy figure may have an 800 lumen light of his own. If he flashes me and robs me of my night vision, I don't want to blindly spray-and-pray and empty a magazine into the room. Better off to blind him back and get outta there.
A corollary: if a flash of light has diminished your night vision, adaptation back to low-light takes time, as we all know. Even if he doesn't have a strong flashlight himself, he may be moving in front of a window at the exact moment a car pours a healthy dose of headlight into your eyes. Expect the unexpected. If your night vision is compromised and you don't have a powerful light in hand, you might find yourself in a--ahem--challenging position.
My training has always been:
- Illuminate
- Identify
- Deluminate
- Move
- Shoot
Yep. Do not shoot while the target is illuminated: just like you would in full light, move off the "X" first, then shoot. Much for that reason, like Carlson, I've never been a fan of weapon-mounted lights on handguns. Don't own one.
The small on-board lights are generally not powerful enough to be effective as a force-multiplier; momentary-on activation usually requires a fine level of manual dexterity that may go right out the window once adrenaline starts pumping; and it leaves you with no choice but to have the muzzle of your gun inexorably linked to the light source...wherever your light source is, there's your gun and gun hand. And did I mention that in gunfights, injuries to arms are extremely common? (You can prove this in force-on-force training, and it makes sense: constraints to your senses are going to clamp down, including tunnel vision...if shots are exchanged, you're going to see the gun that's firing, maybe less so the CoM you
should be watching.)
There are several common handheld flashlight techniques and, while they each have their place, I admit that I only practice two: Harries' and the so-called FBI technique.
I've seen Harries' dissed by some instructors, but I've never bought the rationale. I think much of it stems from the modern isosceles stance taught mainly as a competitive shooting stance. If you shoot full-on perpendicular isosceles, the Harries' technique is going to feel distinctly unnatural and require gray-matter cycles that can't be spared under stress. I've also seen some instructors say that because Harries' requires simultaneous use of both hands, that it can't be performed under stress...as if the Graham, Chapman, Rogers or other techniques don't also require your brain to activate use of both hands. Which you do all day every day.

In fact, I'll posit that the isometric tension required between the backs of both hands actually improves synergistic use of light and gun. Can't prove it, but IMHO.
I've also never been a fan of teaching the full isosceles as a useful defensive stance; but that's neither here nor there. A modified isosceles can adapt to Harries', and a modified Weaver even better. Harries' was just natural to me from day one. Gotta be done correctly, though; burns me when I see actors on-screen doing it atrociously, after probably being told only, "Rest this wrist on top of the other one."
The FBI technique should probably be called FIFE: Flash It From Elsewhere.
No support for the gunhand: you just take the flashlight in an "ice pick" grip, thumb on endcap switch, and stick it out somewhere you ain't. I love this less for general use, but if having to clear a room in low-light from a tight, residential hallway, it definitely has its purpose. Even if you're surprised by a flash in your own eyes, getting your responding flash off the "X" has merit. If all the bad guy sees is a bright light almost a yard from where your heart or head is...not bad.
Carry a high-lumen, high-quality flashlight. Don't skimp on a cheap one.
I've only commented about Abraham's situation in his residence, but it's even more important on the street. No one, not even the NRA can attempt to keep track of assaults or robberies stopped by flashlight. But I imagine there have been many.
Two thugs walk toward you after dark in a Wal-Mart parking lot this time of year? Christmas presents in your cart? If they get close, a boatload of lumens in their eyes and a confident, command voice, female or male, may very well stop something before it ever had a chance to start.
Keep your EDC gun and flashlight always at hand.
