Illumination items

Until recently, the application of incandescent lamps to certain decorative and display uses has been hampered because lamps fitted with the standard Edison screw base were too bulky and lamps for use on regular lighting circuit voltages could not be made easily with the small candelabra screw base. One base was too large to permit the desired delicacy of design in equipment in which the lamps were to be used; the other was too small from a standpoint of lamp performance and manufacturing difficulty.
