Flavio, thanks for the clarification and that's what I thought too. They should have said "USER selects Jetbeam DEFINED mode".
Their language just got me jumping when I thought they were bringing IBS back from the graveyard. I do have a few questions on this light that I don't see mentioning.
1. When using 14500, does the brightness at H,M,L,LL stay the same as when using AA? There is no other stepping available between 140lm and 650lm, correct?
2. As far as I can understand from the manual, 650lm is only available in tactical mode when tightening the head. What happens to this mode when you are using AA battery? Does the light just come on at the AA High mode of 140lm or does it not turn on at all because you don't have a 14500 in there?
3. When using 14500 in tactical mode (650lm), is the light current regulated or direct drive?
