Since I have several unused lights, my only requirement is the light NOT to have high parasitic drain.

I don’t care much about the brand, tint, etc., for I only use my EDC 99% of the time for my lighting needs….but I have ruined several batteries because of horrendously high parasitic drain, namely my Lumintop SD75 and the Nitecore EA11.

I don’t want to become a slave to my memory to lights with that problem, either by lock-out or tail-cap loosening.
