I die in the summer heat here in MN even… my condolences. 
Yeah Turbo will give your position away in a second.
Those are the 2 I want turbo for. In CQC if I’m in control of the light, I’m using it like a handful of sand (to blind/stun an opponent). If you’re using the light to see where you’re going you’ll be a low lumen target. We trained to always move after we turn our lights off.
To each his own I guess.
I believe the best type of light in defensive use is a big thrower. And a .338 Lapua.
Nothing says safety like distance and 250 grains.
In my world any light gives your position away, that’s why we always move after using the light.
Sisyfus, where have you been all these years?!
Low lumens is also less glaring to the user and takes less time to adjust from. If you are expecting the light as the user then good, but in darkness even 500 lumens suddenly to the face is enough to blind and be painful. Wonder how a nice high CRI would do in a combat enviroment? Enough stress on the rest of your body why not take some off the eyes? We also use a lot of IR lights but thats a whole different ballgame. Try driving a 5 Ton truck wearing IR vision with no depth perception.
The one mounted on a 1911.
In addition to the above, better believe at home though Im grabbing the Q8 and smashing turbo to see what the dogs are raising a fuss about in the yard. Suprised someone peeking over my back fence one night with the D4 at full turbo, turns out my poor nieghbor was looking for his cat and was worried my dogs had gotten at it.
I used to be a firm believer in WML’s but now having children I dont exactly want to go see what that noise was in the house somewhere and light up one of my kids with a pistol pointed at them. I am however still a hardcore believer in 1911’s :sunglasses: I will gladly trade round capacity for a hunk of steel slabsides in my hand any day! (edit) I do have a single mode mounted on my ARX as that serves a different purpose and I dont expect to be doing much room clearing in my house.
These two answers exactly. Yes turbo is good for a quick hit and move off target also. Always move off target after lighting a subject.
Yes, However I do not have a big enough thrower to reach out and touch someone at 1,500 plus yards. LOL 
This thread has evolved quite nicely into an adult conversation about “tactical” uses and peoples different needs and uses of defensive flashlights without anyone debating how one way or another is wrong. Quite nice actually.
Imagine a modded BLF GT mounted on a rifle 
HAHAHAHAHAHA
One good use for a quality zoomie… near-zero spill.
Need to put the bi-pod under thick concrete, or the sheer weight will pull it into the ground.
A few months ago, I just got the Q8 and about a week later, got to use it when I heard a thump.
Posted it here and was ROASTED on how I took my life into my hands investigating it. Something about…what if he had a handgun. A handgun? In a very low crime city. In Canada. Where they are so restricted that it costs two grand in the black market.
Now I read post after post on defensive/offensive use of flashlights.
Can you people please make up your minds!
Meanwhile, I’ll keep looking through the Uzbekistan Mail Order Brides site……
Actually, this thread “whut’s a ‘tactical’ light?” was asked a while back.
My answer remains the same. 1 mode only, or at least be extremely difficult to accidentally switch modes, and a forward-clicky (momentary-on) switch.
You want to be able to quietly flash’n’dash, not have to click-on and click-off, also giving away your position by sound.
Now, ideally, you’d want a 2-stage switch, a light press (like on a DSLR) to give low-intensity light, and a full press for going “turbo”. But those switches would likely be less reliable than a single-stage (simpler) switch.
