In order of most often used (and, coincidentally, dimmest to brightest):
Liteflux LF2 Cree (Q5) -- lowest possible setting.
Only a fraction of a lumen, in what I would consider a "narrow flood" pattern -- much more useful than the spot beam of the photon freedom, which was my previous EDC for years, even though the freedom could be similarly dimmed. Perfect for looking through drawers/shelves indoors. Outside, in a true dark environmnet with night adapted visoin, it's can light up wide areas similar to a dim moonlight -- just enough to see my way without stumbling.
Liteflux LF2 -- 33% output
Around 40 lumens w/ 10440s, enough to light up a typical room with ceiling bounce, or seeing my way around outdoors in a light polluted place (night vision doesn't apply).
Liteflux LF2 -- 100% output
Not often used, aside from showing off, but it has come in handy on unexpected occasions when searching for dropped/lost items such as keys on a beach or field. It's nice to have a >100 lumen light with me at all times for instances like this.
8W 1x18650 Xenon, Forward Clicky
The light was build from left-over parts from different projects. This is the light I usually bring if I expect to need a flashlight outdoors, on hikes, etc. Good general purpose incan, runs guilt free for 50mins on a 18650.
2C Mag ROP-Hi
Focusable with a MOP reflector. I've acutally used the light "de-focused" as a portable halogen work-light for things like wiring up sound equipment and cables in dark, hard to reach places. I've also used it to signal drivers where they need to pull off from a main road at night for get-togethers. (by light up myself, or a key sign/landmark, not pointing it at drivers)
Amondotech N30 HID
Similar applications to the ROP. Brighter/longer running (75min vs 45, about 3x the output), with a plastic bowl as a diffuser it makes a good portable worklight. Not used as often as the ROP as it's less portable, and lacks momentary-on.
