Quark Turbo 123, use is EDC
Tighten = Turbo
Loosen = Strobe
I figure if I need to use a lower mode, i'll have time to reprogram (not that big of a deal, takes 5 seconds..), but if I need either of those two I may need it urgently.
I use Turbo 99.9% of the time anyway (use rechargables so I have guilt free lumens
), and strobe when i'm crossing a road at night in traffic and someone is approaching too fast, or on my bike in a fenix holder.
If i'm going for a walk at night i'll typically grab another (larger) light and use it, but if not i'll re-program loose to about medium and use that.
