The fixtures appear to be halogen or LED, so not a very big loss if they got destroyed. At 0:30 you can see the fluorescent emergency lights kick on, and when they are exploring what is left you can see them still working. What really disappoints me is that they dodn't catch the moment the electrical lines broke and the lights went out. 

The main lights are some 150 or 250W MH's, you may see some differ slightly in color...

I think you are right.  Hopefully they saved them, though I doubt it.

WILD!!!!Glad no one got hurt.Yes,could see the color variations of the ceiling lamps as the ceiling collapsed.Then the arc tube glow as the lights lost power.What caused the ceiling to collapse?Looks like the roof is still intact.Would bet the fixtures got smashed beyond use from this.

It looked like they fell slow enough that they shouldn't have gotten that badly damaged. Unless, of course, they were really cheaply made.

Here is another video in which you see the lights go out and the arc tube afterglow.

At 0:25 you can see one of the emergency lights fall of the ceiling!

When the ceiling gets replaced would bet the lights will be replaced,too for safety and insurance Co. regulations.And would bet the bulbs didn't survive this.Tough lamps if they did!

At that same exact time you can also see it hanging from one socket still lighting before it hits the ground
