Product Details
1. 5000 Lumens-Max Output
With a max output of 5000 lumens and a wide 116° beam angle, the SOFIRN SD11 delivers powerful, even illumination underwater. It can light up a wider underwater area with fewer blind spots, ideal for scanning, navigation, and situational awareness in low visibility
2. 2-CCT White Light
Equipped with 6 high-performance LEDs (3*TN3535 3000K CRI90 and 3*TN3535 6000K) the SD11 can switch between warm and cool white light with ease. Warm light cuts through murky water for better contrast, while cool light offers bright, daylight-like clarity. When both modes are activated simultaneously, the color temperature approaches 5000K, and the brightness reaches 5000 lumens. Perfect for underwater photography, cave diving, or simply matching light color to water conditions.
3. Instant Red Light
The 150-lumen instant-on 660nm red light preserves night vision and won't startle marine life. With a quick flick of the Hall-effect switch, you can access four brightness levels ideal for close-range tasks, night navigation, or situations where you need to stay low-profile without sacrificing visibility.
4. Omni-Control Hub
SD11 comes with Hall-Effect switch and touch button, all modes can be switched via the central control button. Control everything quickly and intuitively, switch light types and adjust brightness without fumbling, even with wet hands or gloves.
5. Long Runtime
The SD11 features a built-in removable 26800 7500mAh battery and a Type-C interface. It can achieve a long battery life of 11 hours while maintaining 300lm (low brightness setting). Whether you're diving deep or using it around the house, this light is ready when you are.
