I am EDCing my brand new SureFire G2X Pro ($49, almost a steal) with the fixed loop belt holster (just replaced a NiMH Mini Maglite LED Pro, which replaced a 5 dollar 14500 Chinese clone, which replaced a 9-LED free flashlight). 2 SF 123A. Tacticool/emergency/playing around/secondary normal use flashlight.
In a little flashlight pouch on my cell phone belt holster I am carrying a Maglite Solitaire LED with NiMH AAA. Lanyard included for easy access. Primary normal use flashlight. Been carrying for a couple months.
On my keychain I am carrying a Photon Freedom white LED. Backup/low-light flashlight. 2 Energizer CR2016 included. Been there for about a year. Replaced dollar store keychain light.
As you can see I prefer inexpensive, domestic, and plastic.
Life expectancy: SF G2X Pro - foreseeable future. if work requires continual use bright flashlight, will get RCR123A but good for now
Solitaire LED - a few months. May go Chinese (foursevens, iTP). 2.5 hr runtime too short for my liking.
Photon Freedom - foreseeable future. used primarily for moon mode.
my family thinks I'm a flashaholic but I am quite conservative with my illumination tools.
