Hello,
do you have links to reviews for both light variants?
If not, who owns one or both and can answer:
- runtime chart turbo and high: first 30min with full 18650
- runtime chart turbo and high for 30min for 18650 with 3.6V (or lower voltage) - to see if the mode is as bright as with full 18650
- can you make a mechanical lockout with turn the tail cap a little bit loose?
