Olight S2R Baton III vs Olight ArkPro Lite
Quick take: The Olight ArkPro Lite costs $6 less; the Olight S2R Baton III throws farther (188m vs 94m); the Olight ArkPro Lite runs longer on high (240 vs 2.5 hrs).
Which one to buy
Olight has discontinued the S2R Baton III and replaced it with the Baton 4 Pro, so the ArkPro Lite, about $6 cheaper and the entry point to Olight's current flat ArkPro series, starts with an edge.
Where those 1,200 lumens go is the difference. The S2R focuses them into 8,800 candela and 188 meters, a real general-purpose beam from an 18650. The ArkPro Lite spreads them as a flood reaching 94 meters, and adds a 40-lumen 620nm red light for keeping night vision at camp and a 1000mW 365nm UV for leaks and pet stains. Its 1350mAh cell is sealed, though moonlight stretches it to 10 days, and it charges over USB-C or Olight's magnetic puck.
S2R owners praise the output in a compact body, a well-damped side switch with a built-in low-battery indicator, and a wear-resistant hard-anodized finish. They also report it turning on in a pocket unless locked out, onboard charging that only works with Olight's own cells, and one long-term owner whose unit became unreliable at switching on and changing modes.
ArkPro Lite owners call it a sensible addition to the line, with a flat wedge shape that carries better than a tube and build quality with no fit or finish issues. Their caveats: lower output and fewer features than the full ArkPro, low-CRI emitters, Olight's closed accessory ecosystem, and turbo restricted below a certain charge. For most people buying new, the ArkPro Lite is the easier choice: in production, on USB-C, and with red and UV channels that earn their place at a campsite. The S2R only makes sense at a discount for someone who wants reach and a cell they can swap.
Olight S2R Baton III
Only at a discount, for someone who wants a focused beam with real reach and an 18650 they can swap, and who'll use the lockout.
Olight ArkPro Lite
Best for most buyers, especially campers: still in production, USB-C charging, a red channel for night vision and UV for stains and leaks.
