Footlight Flashes - A Humble Suggestion
Look at these humble AC flashes - they've been around for ages in the trade - I remember seeing advertisements for the in Fred Spira's day. They draw power from 240vAC and ca]n be fired from a standard PC cord or from their own internal slave cell.
There is a power-on light to show when you are connected and a ready-light to show when the charge is sufficient. They fire out at about a GN of 45.
Put them into outdoor floodlight sockets ( See Mr. Bunnings for these. ) and they will synch along with your studio strobes for the authentic stage effect. Put tiny gels in under the plastic dome cover and you can make magic.
