yeah, it could be vray. or mental ray but as these guys have said it does look like they have used some sort of self illuminated material for the ceiling lights. I'd suggest using either vraylight material or a self illuminated material for the glowing lights in the ceiling. Then add some carefully placed spotlights with very soft area shadows for illuminating the space. use GI in vray or mental ray. In vray I would use a combination of irradiance map and light cache with a dark blue tint in the skylight environment override and a few bright coloured walls behind the camera to bounce some extra light around.
