I've noticed that these 1000W HPS lamps, tends to run-up much faster than the rest HPS lanterns, reaching orange color within 15 sec and starts bright xenon white color, while the rest reaching orange color within 30 sec. I've seen this also in other American highmast lanterns.

Note: The brightness variations caused by the camera. All the lamps are the same brightness.

European 1000W HPS lamps are low voltage lamps, and so have much shorter arctubes than the American high voltage S52 lamps.
