single AA light with specific specs needed: magnetic control ring for brightness

[lightseeker2009]

I allready own three single AA lights. But I like the idea of the Sunway M40A with the magnetic ring control for changing the power settings. I now would like to know if there are a single AA light out there that uses a magnetic ring control for different brightness settings?



My Olight T15 also changes brightness by twisting the head, but I would like to set the flashlight to the setting I want, before turning it on.
