I´ve got some really simple idea about the flying lamp for outside. Suppose ther will be more of them surrounding the whole laboratory at night. If you look at the wings, you´ll see a gear and half flap which means that everytime he move the wings it will make a "clap" sound. Also the lower sources of light only hanhang on the higher part, there will also interact with each other, especially in wombination with that up-down flying movement. Therefore it will be kind of noisy (not loud) companion. The sound will be nice, it has to be pleasure to hear that, same as listening the birds sing. Especially when they´ll play with each other, when there will be nobody outside who will need their light assistance. Just a concept...

btw... it doesn´t belong here, but those things around the lab in the picture are floating power obelisks, keeping the laboratory in skies. They will be placed allover the lab and surroundings, everytime in pairs. here is kind of a detail.
