The interior lighting in the new B.O.A.C. hangars at London Airport is automatically controlled by a comprehensive photoelectric system installed by Rashleigh Phipps and Co. Ltd., Esmond Court, Thackeray Court, Thackeray Street, London, W.8. This system ensures that the interiors of the hangars are maintained at a uniform level of illumination both by day and by night, and during fogs. At the same time the photoelectric control, by switching off the interior lighting as soon as the daylight renders it superfluous, obviates any wastage of electricity.
