the lights are on
One thing I did notice about RTE is that the lights are left on.
I'm from a theatre background. When the show isn't on, the lights are off in the "hall". There are usually a set of cheap efficent neon lights available to just as lights to see what you're doing as opposed to lighting the place for the audience.
In RTE, we were more of less free to roam around the empty studios.
The lights, monitors etc were on and blazing.
Now I know that there is a warm up time for the studio lights, but isn't it cheaper (less power, longer life) to turn off the lights, monitors etc when they aren't being used?
