See: The reaction of drosophila to light | .:lab.brembs.net:.
And: Motor deficits in R15A04-Gal80; R48B04-Gal4 after light exposure | .:lab.brembs.net:.

I had 3 vials for negative controls and 3 vials for positive controls

Positive Controls (here I also observed recovery)

There is one more but the video 5 minutes because I tried to shake them to see whether they are recovering, tried to expose them again etc.. I think positive control 2 already shows nicely that they are motor impaired.
