Solid-state lighting (SSL) devices promise to replace conventional light sources, with impressive economic and environmental savings.
'In the US, expenditures for lighting may be reduced by $100 billion over the period 2000-2020. By the year 2020, electricity used for lighting may be cut by 50%, sparing the atmosphere 28 million metric tons of carbon emission annually.'
