10 years in… 332 total, 3 incoming… 
In retrospect:
5000k and less only. No higher unless in a dedicated high power thrower and no other option (for the most part no more Olight, Nitecore, Fenix, Jetbeam).
No flashlights with non-replaceable batteries unless priced as a disposable item (Nitecore, Olight).
I’m okay with Proprietary batteries as long as I can get replacements, and am perfectly fine with lights that use proprietary batteries for in-light charging but can still use normal batteries (Olight)
Avoiding flashlights with goofy interfaces (i.e. high-med-low order, etc that can’t be changed (Manker)).
No more buying new lights that I have to emitter swap immediately on receipt.
I don’t like glued lights.
Take care of the batteries.
