Strobe Light for 4-10+ Miles

Archived from groups: alt.internet.wireless (More info?)

I used to occasionally order one, forget manufactures names. usually twin
bulb automatic change over if a bulb or unit fails and with battery back
up - few hundred bucks a long time ago. Fed Aviation Approval labels,,,
don't ever recall a spec for total distance in miles but certainly FAA has
candlepower or some lumen type light level rating required.

I know nothing about strobe lights, but I live where I can see perhaps
18 miles to the horizon. The strobe lights used on many school buses
are clearly capable of the visibility you need; these are most visible
during the dark winter months, of course.
