Solid-State Lighting (SSL) has the potential to revolutionize the efficiency, appearance and quality of lighting as we know it. SSL is the most efficient lighting technology available; although current products are still in their early stages of development, it is predicted to become twice as energy efficient as fluorescent lamps and more than ten times as efficient as incandescent lamps. As one fifth of global electricity consumption is for lighting, a considerable reduction in energy consumption could be obtained by replacing conventional lighting products by SSL technology. However, both professional users and consumers have been reluctant to embrace solid-state lighting, often due to previous unjustifiable or simply false claims about “low energy” lighting product performance.

To improve user confidence in manufacturer’s claims for this technology, and to encourage its use, an extensive program is required including new research, measurement capabilities, and Standards that will allow unambiguous data on SSL to be determined. Existing conventional photometric guidelines work well for incandescent lighting sources, but when applied to SSL, do not provide unambiguous results for efficacy, light intensity distribution, lifetime and colour rendering.
