Zenmuse S1
The DJI Zenmuse S1 is an enterprise aerial searchlight/spotlight payload designed for multi-payload drones like the Matrice 350 RTK, Matrice 300 RTK, and Matrice 400.
Unlike the optical or LiDAR mapping payloads in the Zenmuse lineup (such as the L2 or P1), the S1 utilizes Laser Excited Phosphor (LEP) technology to deliver concentrated, long-range illumination for nighttime and low-visibility enterprise missions.
Key Capabilities & Features
LEP Lighting Technology: Produces high-intensity light (up to 10,000 lumens) capable of illuminating targets at distances of up to 500 meters.
Energy-Efficient Design: Draws only 17 W to 24 W in High Beam mode, preserving battery power and flight time for the drone platform.
Intelligent Beam Alignment: Automatically syncs its optical center in real-time with camera payloads (like the Zenmuse H30 series) so the spotlight moves with the camera's field of view.
Built-In Operational Safety: Features an automatic eye-protection mode that dims output to 40% when the drone is on the ground to prevent blinding ground crews. Its housing is engineered to stay below 50°C (122°F) to prevent surface burn risks.
Operational Lighting Modes
| Mode | Beam Angle & Range | Ideal Use Case |
|---|---|---|
| Low Beam | 15° FOV / Up to 150 m | Wide-area coverage matching 5× zoom camera views. |
| High Beam (LEP) | 4° FOV / Up to 300 m | Focused, long-range illumination matching 15× zoom camera views. |
| Both On | Extended reach up to 500 m | Maximum intensity combining wide situational awareness with deep range. |
| Strobe | 5 Hz Flashing | Signaling, warnings, and drawing attention during emergency response. |
