The SPERAS S11 is a mini multifunctional keychain light designed for everyday carry, emergency signalling and professional use. Despite its tiny footprint, it delivers up to 400 lumens from the main LED and adds a full-featured side light with white, UV, red, red strobe and red-blue flashing modes – making it highly visible as a police or emergency signal light.
Powered by a
built-in 300 mAh Li-ion battery and
USB-C fast charging (≈35 minutes to full), the S11 is always ready on your keys, vest or duty bag. At only
60.5 × 15.6 mm and about
18 g, it disappears in your gear but is powerful enough to handle ID checks, close-up tasks, equipment inspections and signalling on the range or roadside.
With an IP67 waterproof rating (2 m), 1.5 m impact resistance and a magnetic tail, the S11 is built for real-world use: attach it to a vehicle, locker, weapon cabinet or metal structure and keep both hands free while the light does the work.

Pros & Cons
Pros

- USB-C fast charging with integrated battery – easy to top up from power banks or in-vehicle USB.
- IP67 waterproof and 1.5 m impact rating for hard field and range environments.
Cons
- Small body and single-button interface can be fiddly with gloves in cold or wet conditions.
- Non-replaceable internal battery – long-term life depends on charge discipline and usage.
- Output and runtime are optimised for EDC/keychain use, not for primary searchlight or long-range illumination.
