What owners report
Sofirn SC21
- ✓High-CRI emitter at a price where colour rendering is usually the first thing cut
- ✓Magnetic tailcap and a genuinely deep-carry pocket clip
- ✓USB-C charging with the 16340 cell included
- ✓Floody beam with a defined hotspot — a sensible general-purpose EDC profile
- ✓16340 size makes it small enough to actually carry every day
- ✓Complete package for around $21
- ✗Low-voltage protection only engages on turbo, so lower modes can over-discharge the cell
- ✗One reviewer's first sample had a mushy switch; a second unit didn't
- ✗Runtime is short, as any 16340 light's is
- ✗USB port placement draws criticism
- ✗Easy to confuse with the newer SC21 Pro, which is a different light
Convoy S21A
- ✓2,300 lumens and 280 m of throw for around $17
- ✓21700 mass handles heat better and sustains output longer than an 18650 body
- ✓Wide emitter and tint menu, with custom options on request
- ✓88 grams — light for the cell size
- ✓Impact resistance and thermal protection built in
- ✗Ships in the older, less protective box
- ✗No manual
- ✗No magnetic base
- ✗No onboard charging — an external charger is needed
- ✗Buying means AliExpress and international shipping
