I’ve reviewed the MS03 over here: [Review] Imalent MS03 flashlight review. pocketable, 13,000lm, single 21700, USB-C
Mine doesn’t seem to have the red light issue.
What you already knew:
- It get’s hot fast
- Turbo is bright (makes my 4300lm D4 seem average)
What you might not have known:
- The 3000lm “Medium II” mode throttles too (as well as High and Turbo)
- From turbo, you have to go through off to get to low modes
- The 21700 cell doesn’t fit in an XTAR VC4 or PBS2
The Haikelite MT09R is a triple XHP70.2 light and managed to get 25,000lm from 4 18650s. This should technically be achievable with a single 40A 21700 cell.
