I was aware of the other thread but saw this one as a more how do you use your lights in general as opposed to a specific light used for a task on the day.
I use mine for exploration and photography in environments like this old abandoned iron ore mine:
Cool
Well, here’s my dirty little secret: I hardly ever use my lights! 
Actually, I use one light every morning. Which light has changed over the years, but it’s the same use every day. In the wee hours, when I’m getting up, but my wife is still in bed, I’ll turn one light on Moonlight mode to give myself just a bit to see by without disturbing her. Ever since I won CRX’s giveaway, it’s been his modded SRK that I use. It stays on top of my chest of drawers, which is right next to my side of the bed. The indicator light at the side switch helps me locate it, although I’ve been doing this so long now that I’m sure I could grab it with my eyes closed.
Other than that, I do occasionally use a flashlight to find stuff in dark corners of my basement/garage or to give extra, concentrated light to a thing I might be working on. For that, I grab whatever flashlight is handy. I do carry two flashlights all the time, though I rarely use them. One is my DQG Hobi, which is attached to my key ring. The other is whatever small light I decided to EDC lately, such as my Olight S1A.
I use a S2+ Triple 219C as a constant on floody bike light, paired with another S2+ with dedomed XML, SMO reflector and Bistro’s biking strobe.
Lots of visibility, and no-one can claim they didn’t see me coming :sunglasses:
Here is the one i mentioned. There are more over the years but you will have to try the search and manually go through the tens of thousands of threads on BLF, not something i personally think is worth doing
EDC since 2012 has been my Trustfire F20:
I’ve posted about this light repeatedly, as it sees more use as my ideal EDC than any of my other lights. Highly modded, with CW XM-L2 emitter, Nanjg 101AK no-blinky driver, aftermarket reflector, and replacement switch, etc.
Walking into a dark room, looking under furniture, working on pretty much any project, this light is always on hand. It puts the ‘E’ in ‘EDC’. I grab any of my other lights I have on hand when stepping outside at night to look for whatever made the bump noise, and I’ll grab an 18650 tube light if I’m going to be out after dark. The F20 has been clipped to my pocket nearly every day for going on five years now though, and I will rue the day it is ever lost. The anodization is worn, and it has developed quite a bit of character in the past half-decade.
I use my headlamps more than I use my flashlights. I need bright floody light when I’m working projects around the house. More than likely I’ll be using my ArmyTek Wizard Pro v3 XHP50 for that. I have several others, but the Armytek is my favorite.
That said, I keep my old reliable Dry triple XM-L Coke Can style flashlight by my back door for when I take out the garbage, etc.
Olight I3e stays on my keyring for misc tasks. My area has unlit “community mailboxes” in the middle of each block so this light is used often to get the mail if I get home after dark, plus there are skunks that roam around after dark and I want to make sure I see them.
I’m semi-retired (work for a week or two then off for several weeks) and ride the train into Los Angeles sometimes for work. L.A. was very late getting on the train / light rail bandwagon and the station I use frequently has construction, so I’ll carry an Olight S15R if I’m riding the train. I’ve used it many times to light up temporary walkways at the train station.
If I know I’m going to be out after dark on non-work days I’ll carry a Convoy s2+. See above note about skunks.
And, if I’m not working for several weeks I usually “road trip”. Last two trips were to Sequoia / Kings Canyon Natl Park and Pinnacles Natl Park. I usually bring a couple of Nitecore Tips to use while wandering around inside the hotel room, plus a Skilhunt H02 and BLF A6 to use while exploring. Pinnacles has a few talus caves, and I used both to light the way through.
Thrunite (all in NW):
TH20 - walking, hiking, running, camping, working on the car. Nice and floody headlamp. Great UI, I love the ramping.
TN12 - general purpose outdoor light. Walking, hiking, camping. My perfect flood/throw combo. If I could only have one of my lights this would be it. They’ve just released the Neutron which I would probably buy instead if I were getting one today.
TN4A Hi - outdoors: almost exclusively walks where I can see longer distances and don’t need to keep it in my pocket. Indoors: this is a stable tail stander that I use for early morning light when it’s still dark. Great throw with really wide spill. My favorite to play with right now.
Archer 1A v3 - edc, indoor use, traveling, some hikes where I’ll be out until close to dark and need a “just in case” light. It’s basically a flashlight version of the TH20, although the UI is different.
These are probably more lights than I truly need but there’s a regular use for everything. If I’m in the woods I’ll often carry two lights so I have one for redundancy. I’ve intentionally planned my lights around 18650 and AA batteries.
Torches…. oh, wait.
Yeah torches… 
Kill the monster!!! KILL THE MONSTER!!!
(They are after angry bluish low CRI Latticebright flashlights )
On Thursday night I walk the big trash can down to the road for Friday morning pick-up. It’s a 300 yd walk down there so it’s close to half a mile round trip. I spotlight bunnies, coyotes, foxes, cows, cats, and the all important prowling skunk. Seeing those and identifying from as far away as possible is tantamount to a nice Thursday night walk. 
I usually pick through the lights and carry at least two, maybe 3, as well as a head lamp. Rotation of models is pretty common but a couple of throwers stand out for skunk patrol duty. Rediscovered an old favorite recently, a heavily modified Crelant 7G5 with a clean de-domed XM-L2. Very decent thrower indeed! Easily shows me what’s out at 500-600 yds.
With an impingement in my shoulder and a pinched nerve in my neck, I like applying heat. I’ve found that I have multiple lights that can do this quite nicely! The big BTU Shocker with 3 9V MT-G2’s can really put some radiant heat deep into the shoulder and neck, really helps a lot even if it’s only temporary. Yes, shine the light at the sore spot from 3-6” away and pick the mode level you can endure the longest. lol Plan on trying one of these big lights on some King’s Hawaiian rolls later….
My Ti/Cu Quad is worn daily on the belt or waistband and is used for dropped things (pinched nerve to the thumb makes for a lot of dropsies) and all sorts of general use, from inside the car to out in the driveway, under the bed to the dark confines of the closet, it’s just always on me and always the first light I reach for.
The Texas Poker (Avatar) has been around my neck for 4 years, midnight use and many other scenario’s, so helpful to literally always have a light “on ya”.
I use the BTU Shocker and/or the TR-J20 and/or my DBC-05 triple XHP-50.2 to help illuminate a room for photography, whether a head shot sitting or the family dogs for a client, or just taking macro’s of lights recently built. These 10,000 to 13,000 lumen lights really do fantastic at ceiling bounce.
All the little lights are just fun to carry when going out at night, out to eat or just shopping, if for nothing more than to play with em. From the X5 to Mi7 Ti, from the 3400 lumen Mec Army PT16 to the ( un named proto light) it’s always just fun to pull a great light of the pocket and get people’s curiosity piqued.
The bigger problem is when you have over a hundred lights, you tend to develop a group of favorites and then ignore the others. So from time to time I dig through the back shelf and bring forgotten lights forward for the rotation of play. Keeps things interesting and helps me remember just what is what. (Ok, sometimes I cheat and look them up in the notes. 
)
Forgetting a UI in a once daily used light makes for some interesting purple spots in the range of vision…
I live in the suburbs in a reasonably well lit neighborhood which hasn’t had a power outage at night in 10 years. So… I have to look for excuses to use my lights. Other than just playing with them, I use them as an excuse to walk the dog at 11pm. Because the streets are decently lit, I don’t really need the lights but I use them anyway.
Oh… I also use them when camping but that only happens a couple times per year for me.
Today it was a “nothing much” day:
I carried the S2 in the morning to a visit in my future apartment complex, possibly to look at strange discolorings and telltale fissures or other such indicatives of edifice pathologies (I’m an almost graduated construction technologist, so it’s instinctive). Didn’t actually have much of a chance to use it, because my block isn’t open to visitations yet and a careful look under ambient light on the flat I actually got to visit revealed nothing noteworthy. It matches the positive concrete tests that were run at the laboratory I was an intern in until recently - I definitely snuck a peek on the lab results 
Now less than an hour ago, I used the Biscotti M1 to pick up my brother at the front gate of my house, and then to escort him back to his bike and help him wipe the cat fur off his seat, that my rascal of a cat loves to use it as a nap bed. There’s no streetlights whatsoever in my street, so darkness holds dominion on not-cloudy nights, but even then I didn’t need more than the 1% mode to do it thanks to the M1’s small beam diameter. After he was gone on his merry way, I spent a few minutes admiring the foliage of the many trees around under the 7A tint; I’m not as pleased with it as I thought I would, but that was my pick and I’m sticking to it. Maybe it’ll grow on me as time goes and not seem too gimmicky.
For the time I spent out of the house, as always I had the TN12 at the ready and my almost-new Lumintop Tool (soon to be replaced by a Tool CRI I purchased yesterday on a Banggood sale for $10) riding as a backup. I just don’t like the possibility of being left in the dark without a light even if I’m the opposite of a nyctophobe.
Everynight, I pick a flashlight and take the dog out. At other times when something gets the dog worked up I’ll go and investigate. I live on 10 acres so flood and throw comes in handy, lots of trees. Front pasture is about 600 feet (200m) to the treeline.
Here’s a pic of Lugnut yaking at a deer, across the pond. About 100 meters away (Convoy L6), the deer was not feeling threatened.
Last night I lend my Lumintop Tool for a library visitor who had to mess with his contact lens. The first floor bathroom’s lights are fried, and I wasn’t about to send him off to the second floor with messed-up eyesight; being nearsighted by almost 4 degrees makes me wince in sympathy, as I know what it’s like from the times I lost a lens from my glasses :confounded:
A good deed done, I’d say :innocent:
Just to bump the thread:
Used the Convoy S2 as illumination to take a shower The ceiling lamp is fluorescent in ugly CW, so away with it!
