I always have these 3 lights on me. so these 3 are used the most.
1. Peak Pacific AA: High CRI Seoul, QTC, Brass head, HA body, Brass Momentary switch, MadMax+ driver, McR16 Reflector, UCL lens, moddoo peak clip and deep pocket clip, brass chain lanyard. <- My holy grail of lights.
2. Nitecore Ex10 ramping: High CRI Seoul, Ti bezel, clip, Blue Trit, Droid 58 Carabiner, Sak Classic.
3. Peak Matterhorn Brass: on keychain, High CRI Seoul, QTC, deknurled and polished body.
And when i'm at work, I have 2 more.
4. Spy 007: High CRI Seoul
5. Peak Night Patrol Brass 18650: High CRI Seoul, ShiningBeam 1 amp, 3 mode driver.
Here's a (crappy) pic i just snapped of all 5 of these lights, i currently work nights. never can have too many lights.
