Reebot Robotics (Shenzhen) Co., Ltd., together with the drone Rescue Division of the China International Rescue Center, recently conducted a nighttime firefighting and rescue drill. During the exercise, Reebot’s UniDrone E900 Tethered drone Illumination System delivered exceptional performance and quickly became the highlight of the operation.
Built on the industrial-grade UniDrone E900 platform and a high-capacity tethered power system, the aircraft carried an 85,360-lumen matrix light capable of providing stable, shadow-free illumination across 4,500+ m² from a 50-meter altitude—effectively functioning as an aerial “beacon tower” for complex nighttime emergency operations.
Operational Challenges
In time-critical nighttime firefighting missions, visibility often determines controllability. Traditional illumination tools—ground floodlights and fire-engine light masts—are easily obstructed by smoke, limited by terrain, and unable to deliver the required coverage, slowing down critical frontline and rear-area operations.
Establishing an aerial illumination capability that is immediate, stable, and wide-coverage has therefore become essential for improving nighttime rescue effectiveness.
Targeted Solution for Nighttime Emergency Illumination
The drill deployed Reebot’s UniDrone E900 Tethered drone solution, purpose-built for sustained aerial lighting. The system offers three major advantages:
1. Long-Endurance Lighting
The tethered power system connects to a generator or mains power, enabling up to 24 hours of continuous operation—eliminating conventional drone endurance limitations and ensuring uninterrupted emergency lighting.
2. Wide-Area, High-Elevation Coverage
With the matrix light mounted on the E900, the aircraft provides uniform, shadow-free illumination from above. At 50 meters, the light field reaches a 76-meter beam diameter, rapidly creating a visible “operational zone” for nighttime rescue.
3. Rapid Deployment, Flexible Application
The UniDrone E900 tethered system is highly portable and can be deployed in under 3 minutes. Operators can adjust flight altitude according to mission needs, making it suitable for a wide range of outdoor emergency illumination scenarios.
Operational Validation: Significant Boost in Rescue Efficiency
The drill simulated a wildfire outbreak in a forested area with complex terrain and no available ambient light. Outer-perimeter operations—including command coordination, supply movement, and personnel staging—required stable illumination, while traditional ground lights were inadequate due to limited coverage and terrain obstruction.
Upon activation, the drone Rescue Division deployed the UniDrone E900 tethered drone, completing tether connection, system checks, and takeoff in just three minutes—quickly restoring visibility to the entire outer perimeter.
At a 50-meter altitude, the E900 maintained a stable hover and activated its matrix light, creating a high-intensity illumination zone covering 4,500+ m², including:
-the command post
-supply transport routes
-personnel staging and safety zones
The aerial viewpoint provided a continuous real-time visual feed to the command team, enabling clearer terrain assessment, coordinated tasking, and improved operational safety. Throughout the drill, the tethered drone maintained stable flight with no drift, and illumination performance remained consistent, ensuring uninterrupted progress of all rescue activities.
Firsthand Feedback from the Rescue Team
According to the drone Rescue Division of the China International Rescue Center, the drill demonstrated the UniDrone E900 Tethered drone’s outstanding value for nighttime firefighting and other emergency scenarios: “This exercise proved the operational feasibility and superiority of Reebot’s tethered drone illumination solution. It effectively closes the illumination gap that has long constrained nighttime rescue. In scenarios such as fires, earthquakes, and wilderness missing-person searches, the system can rapidly establish a ‘mobile light station’ over the incident area, giving command teams the visibility they need during the critical golden hour.”
High-Performance, Flexible, Mission-Ready
The UniDrone E900 Tethered drone is not limited to firefighting. Based on current emergency response needs, it can also provide critical illumination in:
-Nighttime traffic accidents on highways or remote areas—creating a safe lighting perimeter for medical, police, and recovery teams
-Floods, landslides, and geological disasters—hovering above levees or hazard zones to illuminate inspection pathways and reveal hidden risks such as seepage or fissures
-Rural or resource-limited rescue units—where fast deployment, long endurance, and simple operation provide an ideal upgrade to existing nighttime illumination capabilities
As the demand for technology-enabled emergency response continues to grow, Reebot remains committed to advancing drone innovation and boosting rescue efficiency. The UniDrone E900 Tethered drone provides a safer, more efficient, and more reliable aerial lighting solution—strengthening the technological backbone of modern emergency protection and safeguarding lives and property around the clock.
