The strobe is quite bright even during daytime. This is a fantastic addition to my drones, especially for the karma, which does not have any collision avoidance. Took it out and at night and performed very well Music a must for night and city night flying in the white strobe mode. It is visible from three miles away from any angle. That is the most important consideration when i picked this light here. Are the others it’s compact enough to fit even the ryze tello Music light enough to not impact the flight characteristics or battery life. Completely self contained can be moved between multiple drones, with simple velcro attachment permanently installed. Rechargeable lipo battery recharges with a simple micro, usb connection, cable included.
