Abstract: The object of this paper is to record major developments in interior lighting equipment and in so doing to indicate the direction in which future developments are most likely to move. A short section is devoted to fittings in general use up to 1940 when the first impact of the fluorescent lamp was felt. The effective use of high-pressure mercury vapour lamps is considered and the value of horizontal burning lamps is emphasised.After discussing some of the problems in the design of standard fluorescent fittings, with a particular reference to the complication caused by the many different types required, brief analyses are given of the lighting units required for some special types of installation.For example, in a power station, the crane rail may be used as the main rigid structure for fluorescent lighting fittings built around it: commercial fittings have also been designed on this principle. Another interesting technique uses composite fittings of metal and plaster, since plaster can be formed easily and cheaply to a desired curvature.The author believes that fundamental changes are now taking place in the mechanics of lighting practice, which may have a far-reaching effect on fittings design, but that progress may be hampered by too great complexity. Advances in lamps are inevitable and desirable, but every effort should be made to rationalise the design of lamps and components to assist the fittings maker in reducing some of the many variables in his equipment.
