Hello to everyone. Although this is my first post, I have been looking at the forum for a while and bought enough flashlights to lie awake at night thinking about flashlight designs.
Specifically, a round (U.S.) sardine can design, based on 2 transversely situated 21700 cells: heatsink fins located in the two segments not occupied by the batteries: the head with a diameter of less than 100mm would provide ample space to locate throw, flood, and auxiliary emitters: 2 buttons, one for mode (throw, flood, or both) and the other for the UI: the tail could support a strap to insert 3 or 4 fingers to hold the flashlight firmly: judging by the EO7 & D18 specs, the cells would support about 10,000 lumens on turbo. In a 50mm cylinder - twice the size of a hockey puck - it would put the Q8 in the shade.
Is it realistic or desirable? Could it be a BLF project?
You’re right. I was thinking of the round tuna cans, rather than the sardine cans you describe.
This configuration would have two benefits: it would have a large area to configure the emitter array(s) and would be more easily pocketable than the normal fat or long cylinder designs for multi-cell flashlights.
I only eat the peeled and seedless ones. I ain’t a cat.
Yummy, but the stank gets alllll over ya.
Still trying to visualise the proposed light from the description… not sure I’m “getting it”. And I just had a can o’ tuny-fish not more than an hour ago. Where would the head stick out from the can?
You could carry it in the back pocket of your jeans like a can of Skoal or something. We use to build full blown transceivers in Altoid tins, just because we could.
If it is to house two 21700 cells, like OP is suggesting, then it’ll likely be larger than a can of Skoal, but I get it. For me, something like a Convoy S2+ fits in jeans pocket just fine, but I suppose a cob-like ‘puck’ could be more versatile.
