Re: Zebralight new 21700 flashlight
Praise be to the Lord! Finally a 21700 offering from ZL! I almost thought they'd never do it.
21700 is really the perfect size for a single-cell light. The battery itself is thinner than SC600's bezel, yet it enables a ~50% increase in capacity (which is sick considering the size) and well enough power to melt your face off if need be. The new light does, however, have a larger bezel, but I believe this is to accommodate the new monstrous XHP70.2 LED rather than serve the needs of housing the battery.
With that said, I'm going to assume they will discontinue the SC600 series in foreseeable future because SC6x still exists and fulfills the need for a compact affordable Li-ion EDC, and when you need significantly more power than it can provide, choosing SC600 over SC700 doesn't seem particularly enticing.
Anyway, this is a must-buy. As somebody who has used the original SC600 and SC600 mk. II L2 extensively (this series has been my go-to light since 2012), I say this is quite the opportune time for an upgrade.
Now if only I could get my hands on a couple of those Tesla 2170 cans, ha... ZL will probably offer repackaged Samsung cells to go with it. At least that seems most likely, because Samsung's are the best option currently available on the open market.
