High pressure sodium hot restriking and contrast demo

This is one cool thing about high pressure sodium lamps: the way they restrike when they do a hot restrike. A hot restrike is when you turn an HID lamp off without giving it time to cool down. HID lamps need to cool down before they can restart so there will be some off time. High pressure sodium lamps unfortunately do this a lot due to their sensitivity to voltage fluctuations. The rewarding thing however is the cool lightning bolt strobing effect that they do. Also shown in this vid is the low color contrast HPS lamps tend to have. I talk about reasons why I dislike HPS in most applications although I will admit there are some occasions where they work well such as in foggy areas or as a grow light for your indoor palm tree or bamboo plant, even in situations where the color compliments the architecture. none the less, enjoy the cool lightning bolt effect and a color that is irritating to the eyes.
