Is there a record for how far away a LED flashlight has been seen?

This is in regards to handheld LED lights.

 

If you have the right light pointed at you and you know where to look how far away can you still see it with the unaided eye? 50 miles possible? How about 100 miles?  How about looking out the window of the space station? I have see strobes on jets from over 100 miles.

 

Would it be the light with the most throw or a brighter one with larger/more LEDs but less throw?
