Sofirn SC21 Flashlight Review
Official Specs and Features
Here’s a link to the Sofirn SC21 flashlight product page. This is not a referral link.
Versions
There is just one version of the Sofirn SC21 flashlight. It’s available as a kit, too though.
Price
Without the cell (“SC21 Alone”) the package is $20.99. With the cell (“SC21+Battery”) the package is $23.99. If you make a purchase, I recommend grabbing the kit – the cell is worth the extra $3. This light is available on Sofirn’s newly revamped website!
Short Review of the Sofirn SC21 Flashlight
For $21, the Sofirn SC21 flashlight is extremely hard to beat. The size is great – despite nearly everyone forgetting about 16340 cells, they still make for great EDC flashlights. Aside from size, this is a feature-packed light. Indicating e-switch, tailcap magnet, USB-C charging, and a nice reflector…. There are a couple of things I don’t care for so much, though.

^ Measurement disclaimer: I am an amateur flashlight reviewer. I don’t have $10,000 or even $1,000 worth of testing equipment. I test output and such in PVC tubes!! Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).
There's more at my site, including runtimes and all that other good stuff. Head over there if you're willing, and if the table above doesn't satisfy your need for data. A bunch more photos, too!
