How do you get the light on in the xray room?

I can't see in the main room to find the glass shards. I can see the window when I zoom in but the rest of the room remains dark. Is there a light somewhere I am not seeing?

i am not that far, but you could look at the guide if no one else is either....

I think you had to click on the electrical box on the wall on right side of screen. in main hall of floor that x-ray is on.
