Kraken Sports Unveils KR-S40 Entry-Level Strobe
By DPG Editorial Staff, May 15, 2025 @ 01:00 AM (EST)

After introducing the KR-S160 and KR-S80—boasting 160Ws and 80Ws of power, respectively—Kraken Sports has announced a new entry-level strobe, the KR-S40, offering an output of 40Ws (guide number 16). More compact than its more-powerful siblings, the KR-S40 features the same aluminum construction, optical triggering and remote controllability, but a straight flash tube rather than a circular one.

Strobe power can be adjusted manually using the big rear dial (five levels), but there’s no TTL automatic exposure option. Unlike its siblings, the new strobe has no dual function as a video light, but there’s a 500-lumen target light built in. According to Kraken, the strobe recycles in 1.5 seconds after a full power dump. The KR-S40 is powered by a single high-capacity 21700 battery.

The Kraken KR-S40 strobe will be available soon from retailers such as Backscatter, priced at $360.
