ML4 UAV Searchlight Device

China Moneypro

The ML4 UAV Searchlight Device is a professional-grade aerial lighting system featuring a 2-axis stabilized gimbal with four LED lights delivering up to 4000 lumens. Equipped with precision motor control accurate to 0.02 degrees, it provides stable illumination up to 150 meters away. The aluminum alloy housing includes integrated cooling and vibration dampening for reliable performance. Supporting multiple control methods including PWM, TTL, and optional SBUS, it integrates seamlessly with open-source UAV platforms. Compatible with Viewport quick-release connectors for easy plug-and-play assembly, the ML4 is ideal for night surveillance, emergency response, search and rescue, and firefighting operations. Operating in temperatures from -20 to +60 degrees Celsius, it delivers professional lighting solutions for public safety and infrastructure maintenance applications.

L4 Searchlight features 2-axis stabilized gimbal with 4 pcs LED illuminating system, luminous flux is up to 4000lm, light can be switched on/off with remote controller. Integrated aluminium alloy housing with built-in cooling fan are optimized for heat dissipation and anti-interference. Vibration is eliminated using four damping balls and a lightweight damping board. 300 rotation remains possible through gimbal rotation. It has an operating range of up to 150m and can be easily integrated onto open source UAV platform, lighting the space at night or in utter poor light environment for users in night surveillance, emergency response/search and rescue, firefighting
