1. wide open throttle
2. bright enough (at least 300lm)
3. bright enough with occasional blink (if this is your only forward light, good for oncoming traffic after dark). My Cygolite has this but my new Kaidomain light does not
4. daytime blink mode that is noticeable but not irritating
Also I want, turn off without cycling through all the modes, open circuit when off so it doesn't drain the battery over the course of a week,
My new Kaidomain light has 3 levels and two blinks. The first is an SOS blink mode that is not SOS, SOS, SOS but instead SOSOSOSOS... I don't know if this is "correct" but it's the one I use in daylight because the other blink mode is a strobe and I don't actually want to do that to anyone. There's another version of the model that has more modes.
