My personal critique of it is that NIMH modes are underwhelming. Per 1lumen review of v4 version:
- main mode 1 level - 6 LM
- main mode 2 level - 20 LM
- main mode 3 level - 57 LM
- turbo 1 - 84 LM
- turbo 2 - 127 LM
To me there should not be a point to call turbo level what should be sustainable and clearly 200 LM should be sustainable if driver is efficient.
Proper spacing imho should be on NIMH AA to make it truly competitive with d3aa or kr1aa (hopefully one day we will have more throwy sibling in that family):
- main mode 1 level - 6 LM
- main mode 2 level - 70 LM
- main mode 3 level - 150 LM
- turbo 1 - 250 LM
- turbo 2 - 400 LM
If mode is sustainable it should be in main group UI. I still probably will buy it just to see if F35R led option any good
