The Radium 250W is designed to operate on a HQI ballast. This combination typically gives the best performance.
The problem now is lamp manufacturers are having to alter lamps to meet certain global standards. This has made some lamps more sensitive to operating and starting parameters. In this case many German lamps have removed Kr-85 and lowered the mercury dose. Making starting more difficult.
