You likely already have to charge batteries all the time in Photography,I know I do for Event Work for sure so maybe this is not a big deal for you but to me the SC5 is also just bigger enough to be bad to EDC for me compared to the SC52.
One thing I do know for sure though is that if you get 1 ZL there will be more!
The SC5 is a non starter for me for a pocket light when there are smaller capable options.
Yes, as a photojournalist and a budding flashaholic, I've got a half dozen chargers going on my desk at all times.
Now that I've gotten used to the UI on my first ZL headlamp, I love the ability to program three modes and either long press to scroll through or access the exact mode I want with a button press or three. I do wish they were tail switched and of a more traditional and attractive form factor.
