Strongly agree. There seems to be an unstated but well intentioned belief as hinted in the beginning of this thread, that the more itsy-bitsy teeny-wheene the form factor and size the better. That of course is a gross oversimplification, as the above research clearly states. Furthermore it woud make our design decisions far more taxing.
Is there an unstated belief that the fictitious granny needs something unthreatening that of course resembles a girly cylindrical lip-stick?
N.B, A clean cylinder is one of the worst shapes since it will roll off any uneven surface and by Murphy’s Law straight under a heavy item of furniture. Presumably, one would then be called upon to find torch to try to locate it! Common 18650 lights typically have a pocket clip which presumably won’t be used here?
@hank&others, thanks for the research and norms, I guess then that this will not become a proper grandma light then, at least it will not be for the granniest of granniest
One of the starting points of this project is that it must be an attractive light for flashoholics too (it must be fun to give this light away with a certain proudness) , and going back (with all respect) to D-cell Maglite format whith the performance not different from a S2+ does not sound attractive to me. I must confess that my personal preference for compactness in flashlights plays a certain role here :innocent:
Good news:
The two positions that djozz states above are NOT irreconcilable. I propose a bone shapes light. Something not a cylinder but more along the lines of a Klarus 18650 but presumably little less tactical looking. No need for strike bezel capability!!!?
So the bone shape would include: A wider head radius -makes flexibility of led carrier MCCB design of an/all mods much easier. A purposeful tail flange to facilitate grip and prevent rolling around. Possible space for tail electronics / magnetic charge port etc.
-Whilst aiding to satisfy grip ergonomics.
Remember that the mark of good light is that it is easy to hold and operate whilst wearing thick gloves. Elderly persons often wear thick gloves sadly even indoors. They definitely will when faced with the need of sudden winter tasks outdoors such as e.g.locating a missing pet animal etc. You too will appreciate glove-friendly bone-shape when indulging in sub-zero WROL camping survival.
As indeed always for all discerning BLF users, deep and proper traditional knurling is a must for winter etc reasons and the leading picture of the thread points to this.
