Thank you! martonic.
It is important to start at a high setting and then reduce the level while the light stays on.
It is also important to start at a low setting and increase the level while the light is on.
They exist. For example, you can set the left to the highest level, and the right to the lowest level, as I did.
It is also important to reduce to a low setting, and then turn the light off without increasing the level to do so.
Yes. It also exist. When I want to turn the light OFF, right and hold won't increase the brightness.
I like the following concept:
When the light is off:
Twist right to turn on at the highest level. Hold < 2 seconds for momentary, or hold for > 2 seconds to make the light stay on.
Yes. It's what S2 can do now. Any level.
Twist left to turn on at the lowest level. Hold < 2 seconds for momentary, or hold for > 2 seconds to make the light stay on.
Yes. S2 can do it. But at left, the time is about 5 seconds, not 2 seconds.
Users could choose left:5 & right:2 or right:5 & left:2.
When the light is on:
Twist right to increase the level (twist right and hold for ramping up).
Twist left to decrease the level and/or turn the light off (twist left and hold for ramping down to zero).
We want to keep the voltage gauge function, so there is a bit difficulty to add ramping up/down.
Use tailcap lockout to memorize the current level. Release the tailcap to turn the light off at the current level. Engage the tailcap to turn the light on again - still at the last-used level.
Yes. You can set both the left and right turn.
About 10 levels might be ideal - each one double the current of the last. That gives a dynamic range of 1028 to 1, or from about .7 ma to 700 ma.
For me, this would be perfect. Low to the left, high to the right. Simple!
Thank you for your advice!
