If its any consolation, I don't remember the menu order either. And I designed the thing! The last time I was in the menu was to show someone how it works. Day to day to use, I have it come on at L16 and I double click or push to get more light when I need it. I use rechargeable 123s and get about 2-3 weeks per cell.
I like things that save me time. Helps me spend more time reflecting on life instead of spinning in the hamster wheel. The way I use the Arc4, I typicaly press the button 2 or 3 times for a complete usage (turn on, pulse full power, turn off). I use the light mostly in the house at night and it already comes on at the level I use most of the time.
To give the Arc4 a fair chance, I recommend two things:
1. Treat is like a flashlight. Don't worry about the click and stand on your head and count to 5, etc. Just use it like any of your other flashlights. When you are ready to add another method, go for it. But only stick with what saves you time and batteries because if you use it right, it will do both. I believe that.
2. If you absolutely feel you are in some sort of race to figure the light out as fast as possible, give it a week. I felt like I had to master the light pretty quick when I got the first prototype but it still took me 4 days just to start liking the interface. I hated it the first couple of days. It drove me absolutely nuts. But now I use the light every day and don't give it a second thought. Why is that? It takes time for new connections to form in our brain and solidify. The first time I drove a car, it took all of my concentration. Now I can do it in my sleep.
Good luck guys.
