Then I might shift the Energizer to my get-home bag in the back of the car, displacing the older Innova X05 (I think that's it). The Innova is nice, hard aluminum body, good beam. But I've come to not like the twist (several times) to tighten tailcap to turn on. Also, being an older technology LED it tends to burn through -123s (especially the rechargeables) pretty fast. So the Energizer and a couple of pairs of spare batteries would displace it.
What do I actually use lights for? In the past few months let's see... Work lights working around the house on minor projects. Work light under the hood of my car. Carry light when I'm in town at night (not the only thing I'm carrying ;-) Walking my dog at night, setting up gear at night outdoors. (long story) Camping in the mountains and in the desert. Helping a couple of young girls search for a dropped ring in a supermarket parking lot. (found it!) Flagging down traffic to slow them at an accident site.
I don't expect one light to be good at all these things, that's why I have several. Well, that's what I tell myself, actually I just like to have several around and choices. Camping and setting up gear at night I tend to use the bigger lights, the Coleman and/or the TK-35. I also have a rechargeable Coleman electric lanterin for ongoing illumination and a Porter-Cable work light that shares battery packs with my cordless drill. The smaller form factors are what I like for a EDC type light. Something you have on you or with you at all times. Also, where I work is in the basement of a rather large building. In the event of a power failure or evac I like to have a light with me just in case the battery powered emergency lights don't work. For that I keep a couple of the el-cheapo AAA powered LED lights at my desk. Just enough to illuminate the floor in front of me as I crawl out if necessary.
As for headlamps, never really got into them. I guess they help keep your hands free for some things. In other cases I like to be able to point and direct the light by hand without having to move my head.
The Fenix PD35 is hard to beat as an EDC and all round light. I carry it on my belt.

For a headlamp that uses the same battery (both of these lights use either a 18650 battery, or two CR123A batteries, this should blow your mind.
It gives lumens, but it has a slide switch that gives you total control over brightness.

Some high quality headlamps have good flood that lights up the entire area, it doesn’t have the small focused beam that they all used to have, and that are good for running or bicycling, when you don’t want to outrun your focused beam.
Some head lamps like the one I linked, are powerful enough to do both throw, and flood at the same time.
