I like the idea of a powerful and affordable light. If it supports an up and coming battery size, it makes me even more interested due to the extended run time and with more cells potentially coming in the future, it looks like this one might not be made with planned obsolescence.
Yes, there’s precious little information given, but what it could potentially offer is interesting to me.
Actually a D1S-sized thrower host with 21700 is exactly what I’ve been contemplating recently.
Or maybe slightly larger.
This one may be the closest so far.
