Unfortunately we’re talking microprocessor controlled circuits which are not analogue. There are finite steps.

I haven’t taken this item apart, but not all circuits are digital. Granted, most of them are these days… but I’m not ruling out the possibility.

There are an infinite amount of numbers between 1.0 and 2.0. I mean, there’s the obvious 1.5 in between, but then 1.25 and 1.75 between those, and 1.125, 1.375, 1.625, and 1.875 between those, etc… Infinite.

Of course, there’s an even bigger infinity between 1.0 and 5.0, and an even bigger amount between zero and, er, infinity.

Technically, an analog stepless output is still not infinite though… because there are a finite number of positions we can actually turn the control ring to. I tried to count one day how many different levels I was physically able to access, and the number was only two digits. Pretty far from infinity, if you ask me.

Plus, I suspect that either the ring sensor or the output driver probably has a maximum effective resolution… much like how pictures from a film camera can only be blown up so big before they get blurry. It may be analog with a resolution only theoretically limited only by individual molecules in the film, but an average 35mm analog camera still won’t give me sharper pictures than a 24 megapixel digital SLR.


At max brightness there is a measurable number of photons coming from the light, so the theoretical maximum number of steps is from zero photons to the lights max output, a huge number but not quite infinite

"It is critical that there is a credible academic source for the growing and important discipline of alternative facts. This field of study will just keep winning, and we knew that all the best people would want to be on board. There is a real risk in the world today that people might be getting their information about science from actual scientists"

That’s a good way to explain the theoretical maximum “resolution” of a light. Smile

I’m guessing its effective resolution is relatively low though; dozens or hundreds of levels at most.

I haven’t really used my RRT01 much lately. It’s a sweet little light, but I find that it’s too wide to hold comfortably, I compulsively check and re-check to make sure it’s turned all the way off, and I apparently prefer having known output levels. I use fixed levels to gauge how night-adjusted my eyes are, and to get an idea how long I can expect the battery to last, but the RRT just leaves me wondering.
