I don't get it. Supose I'm working in an environment or on a task where I need 50 lumens. Every time I switch the light off, I would have to click twice, then double-click to get back to 50 - seems a lot of hassle just to get back to the level I was using a moment ago.
The RA seems to me a better way of managing the levels. Depending how ou have it programmed, you can have momentary at any level you want, plus quick access to max, and you can decide whether you want it to retain your last-used level or not.
