||Following the launch of GE's Genura, the world's first commercial self-ballasted electrodeless lamp, interest in the technology was renewed among other manufacturers. Whereas GE's lamp was offered only in a reflector format due to that company's belief that the induction technology was too expensive to enable it to compete against the ordinary pear-shaped incandescent lamps, OsramSylvania came to market some years later with both a reflector as well as an A-shape version. For a very brief period, the parent company, Osram GmbH, also offered the A-shaped version in a 230V 50Hz rating for European markets.
The American Dura-One lamps were positioned alongside the company's compact fluorescent products and marketed as premium performance versions. One of the primary advantages is the increase in life to 15,000 hours, roughly double that of compact fluorescents of the time, as well as insensitivity to frequent switching. Thanks to the use of strategically positioned amalgams the run-up time is fast, just 5 seconds to 80% flux. Another strength is the stable light output over wide temperature ranges. CFLs cannot be used in cold outdoor environments but Dura-One enabled energy savings to be extended to replacing incandescent lamps in such applications, being suitable for use at ambient temperatures from -30°C to +50°C. At 0°C and -10°C typical CFLs drop to about 50% and 25% luminous flux, but Dura-One remains well over 90% and 80% respectively.
Despite all these advantages, the high cost played against its success in both the A-line and reflector versions. In particular following the development of high power LED retrofit lamps, production came to an end around 2012.
