 Most manufacturers have been releasing lamps for many decades. Lamps produced in the 70s and early 80s are probably not commonly found today. In the 90s and early 2000 Philips was manufacturing lamps in Holland and other countries, while in the last years they were doing the same thing in China. Quality was not severely affected as manufacturing quality was maintained and applications were demanding, used in wealthier as well as poorer countries. It should be noted that sodium vapour lamps were mass manufactured and considered mainstream products, meaning that quality and reliability had to be consistent.
-Products manufactured by Philips were similar to General Electric and Osram, with a quality and consistency much above some East-European manufacturers in terms of colour rendering, light output and life. However, Philips was manufacturing lamps with shorter lifetimes than typical Osram ones, as the datasheets and installations performance shows. These differences are maintained even nowadays. Philips lamps, however, were much more popular and are easier to find.
+Products manufactured by Philips were similar to General Electric and Osram, with very good quality and consistency and Japanese manufacturers such as IWASAKI deserve a special mention as they were creating excellent lamps. Philips lamps, however, were much more popular and are easier to find.
