(Some estimation of levels here since most were pulled off the ramping sequence)
Loose Head: .1 -> 1 lumen -> 5 lumen
Tight Head: 25 lumen -> 80 lumen -> 250 lumen -> Max (400+)
Semi regulation, mode memory on, 18650 mode.
Loose head with diffuser is generally my indoor configuration, tight head is usually my outdoor mode. I could probably condense my second line down to 3 modes but I like the way it's setup right now. I like having the mode memory because even with many modes to pick from, you can just treat the light as a single mode light with momentary ability. The UI is excellent and easy to explain to a new user as well. Sure the programming requires some learning, but general use is very reasonable.
