I too have a large range of lights - Fauxtons, AAA lights, AA lights, 16340 lights, 18650 lights, 2 x D - 6 x D lights. Some lights are not used much and live in a drawer, some are 'show off' lights and not that practical (180+ watts of incan power with 10 minutes of run time). But plenty of my lights are used for the tasks that they are suitable for.
Around home:
Maglite 2D ROP Low - very useful, plenty of nice white light.
In the pocket:
Nitecore D10 R2 - useful and versatile light that is a good size to fit in a jeans pocket. I'm a computer tech and crawling under a customers desk to check a PC can be a job then NEEDS a flashlight - it can often be too dark to see anything (like a fan not spinning, clogged heatsink, bulging capacitors).
On the keyring:
Fenix L0D - for a small AAA light this is very useful and makes a great backup for whatever else I use.
Camping:
Zebralight H60w - not at all big despite the 18650 cell and with 2600mAh there is a lot of run time available. Six levels of light available - you can always get the right amount of light. Can be clipped to your shirt for hands free use.
Jetbeam Jet-IIIM - plenty of light & throw on high, VERY low minimum for when it is pitch black and bright light would be painful on the eyes (but you don't want to trip over stuff when going for a leak.
Maglite 2D ROP High with 2" deep reflector - so much light, so much throw and such nice colour rendition from the incan output. Good to show off and good to have if someone else has a bright light that you obviously HAVE to out do! Great light to light up anything near or far!
Surefire A2 Aviator - I don't have one yet, but when it arrives in the mail then I'll be sure to use it heaps.
