I understand you can never have enough lumens... But how much is enough for certain tasks? Lets leave out S&R and tactical use.
Lets not focus in throw vs. spill too much in each scenario, although of course you can give a preference.
Max Lumens the light should have:
Walking the dog in suburbia?
General in-house use?
2 day blackout?
Car breaks down? Flat tire at night?
Walking in the woods?
