Every year we all hope there will be a wonderful new light source but tungsten and discharge still dominate the lighting industry. To aid the production of a higher light output from luminaires, lamp manufacturers have made some progress by producing tungsten lamps with more compact filaments and discharge lamps with shorter arcs. This allows the concentration of the light output by utilising the optics more efficiently. There are hints of important progress in the production of light from Light Emitting Diodes with suggested outputs of around 100 lumens/W. One tremendous advantage of LEDs is that the majority of their output is in the visible spectrum, thus avoiding the generation of ultraviolet (UV) and infrared. At this stage, it is difficult to envisage devices such as these being used in conventional luminaires.
