i have pretty much every strobe light imaginable; let me know what details you need.
close up of vifly attached to skydiothe arc v is considerably brighter and definitely can be seen in the daylight but know that it is a bit larger so you need to be sure it is away from the props or the cameras. it is semi-rugged so no problem with landing on it during an emergency. not sure if it is waterproof or will survive underwater long enough to see it flashing. definitely would help if your drone crash on land or gets stuck in a tree. since the skydio is mostly a daytime drone, not much detail on use with strobe lights.
also i attach one of these to my skydio to help locate it in the event of a crash. the audible can be heard quite easily and will come in handy if the drone buried in the thick brush or up in a tree where otherwise not easily seen.
