About runtimes, performance and priorities.

So, I've been thinking.

From the way I approach hobbies and hobby research, I have always tried to read as much as I could, watch as many hobbyist videos as possible and learn about the underlying science (which is particularly challenging in the case of lights, because electronics are not simple and not a thing you can just learn in a few hours). I have been consuming quite a bit of flashlight content for the last, say... 6 months or so, and I am very surprised by the focus of the content, or rather by the lack of focus on some aspects, namely runtimes and performance.

I understand that lumens sell to the wider public, and that for some people rosy tint and warm CCT is the absolute priority. However, those things for me necessarily have to be somewhat linked to a runtime. I am now familiar with the term "hotrod", and I don't like that. I don't really want to be walking out there at night with a flashlight that gets dimmer and dimmer by the second.

This leads me to my next point: what's going on with runtime graphs? Why would companies not provide a graph like this one: https://imgur.com/a/JomqNsZ ? (Extracted from maukka's review for the Noctigon KR4 here https://budgetlightforum.com/node/72632 ) Most important, why are those not more common in the community? What equipment is needed to get the necessary data to plot one of these? Is is that expensive/inconvenient to do that only a few of them are made?

I've come to wonder this because of the very same Noctigon KR4 and boost drivers. It's bewildering to me the fact that I cannot find a graph comparing lumens/time for the same set of emitters on a stock driver vs the boost driver for the KR4, or the even more popular D4V2, despite quite a bit of research (maybe I'm selectively blind, but I don't think so. If you know of something like this, please feel free to call me out). The closest I've gotten this far is this post by Grizzly's Reviews on the more recently released D4SV2 and, even though it's brilliantly put together, that's only for one level (around 275 lumens) and also different to the other lights due to different thermal mass, I assume: https://tgreviews.com/2022/04/28/emisar-d4sv2-review-three-versions-compared/.

As I understand it, a lot of people treat lights a bit more like toys rather than tools, which is fine and a natural progression of any hobby, if you ask me. However, I think there is a market for people like me, who like our tools to be cool and pretty and are efficiency nuts, always trying to max out on our desired specs. I could use a super efficient workhorse beast just as they come, but I don't feel like I should have to sacrifice the cool factor and the lastests developments in flashlight tech in such a capitalist market (even if that makes me a bit of an entitled brat).

Anyways, thoughts, suggestions and insults are encouraged.
