Re: Brightness of streamers vs. ground strikes



Original poster: robert heidlebaugh <rheidlebaugh@xxxxxxxxxxxxxx>

An additional consideration, When a streamer travels through the air only
air creates light for the eye or camra to sence . when a streamer hits am
object light is produced by what ever is hit, irom , copper , chrome. This
produces light of additional colors of emmision and light intensity.
