Night time! with the blue tubes and LED's on.

Halides are on for 8 hours each.
They go off 15mins after eachother which leaves 2 4ft white T5's at the front and 2 3ft blue moons at the back on.
These stay on for an hour after the halides go out and then the white T5's go off.
Finally, the blue moons go off half an hour later and then 16 blue LED's stay on throughout the night.
