These lighting gantries use the old round pin plugs found in UK before the fused flat pin ones we use today. This appeares to be standard wherever I have seen the roof/wall mounted stage lighting.

It gives an extra few amps capacity, and if there's an overload or fault it will trip a breaker in the control panel, and not a fiddly fuse 30 feet above the stage. They are not wired as ring circuits, but as radials/ finals, so there is no requirement to have a fused plug. Not many are still 15amp plugs, there are more modern connectors nowadays.

All the so called sockets on a stage area are round to avoid anyone plugging an appliance into them by accident
These are not conventional outlets but are dimmed circuits designed to be controlled by a live operator or computer time code.
If a cleaner plugged a heavy appliance it could cause havoc to the system and production.
A traditional set of Square Pin 13A sockets are always present but often at more strategic locations.

I'm fairly certain its to do with the voltage of the lights used in theatres. They are very high powered, so I guess need something different than normal.
