Like Joanne, I use my headlamps primarily for mineshaft exploration.
(we're friends, she's an amazing camp cook
)
I have tons of pictures of me using all my various headlamps!
Looking at dynamite is important. Fenix HP20, w/ surefire diffuser.
For seeing in very dark places. Like Joanne said, it's life-support equipment underground. Custom "Speedy Special"
Dual Fenix HP20's (one with a surefire diffuser)
Dunno what's going on with my friend there, but she's using my Fenix HP10
Tight crawls Fenix HP20 w/ surefire diffuser & HP10

Other off-brands I can't recall at the moment.
I managed to break all three Fenix HP20's.
Every single one the wires inside the cord eventually broke somewhere and one also had a switch which malfunctioned. It's a poor design.
One HP20 started malfunctioning, then the switch failed and the light died while I was 500ft underground and about a mile into a mine. I switched to a Energizer backup, and started to head back to the surface, then promptly bashed my head on something and broke that one, then switched to a Petzl Tikka 2 with the realization that I was swiftly running out of lights, and began to tread quite carefully. I was down to that backup headlamp and a handheld.
Before that trip I always pushed the "Always take 3 lights" rule when going underground. Now I usually take about 5 to 7 on extended forays.
Usually a Primary headlamp, a backup headlamp, and a backup backup headlamps, along with a primary handheld, a backup handheld, and sometimes a backup backup handheld. Also batteries for all!
(you can go through quite a bit of lights and batteries when you're underground for up to 12 hours straight, plus consideration for possible emergencies).
I purchased my HP10 as my first Fenix headlamp, and it's still going strong
, I've since modified it with an XT60 connector to accept either it's own battery pack (also with an XT60), or a custom LiIon pack.
The HP11's are great lights. I used them for underground exploring, working on wind turbines, reading at night, all kinds of stuff.
Then I got my custom "Speedy Special" (by Speedy Caver), which is my primary light for underground use now.
The Petzl's are indispensable. I use them for EVERYTHING.
Oh almost forgot one, storm drain exploring!!!
(I have no idea which lights I'm using here, it's just a cool picture)
