How does that work? Higher pressure?
Can you show it lit next to a normal 400W HPS? (if you have 2 ballasts I mean)

I have one of those myself. See here this is the comparative of my normal and the deluxe!!! Same wattage! Mine is 70 watt

yes, the better color rendition is achieved with a higher sodium vapor pressure which results in more absorption of yellow light inside the larger burner.

That's a very nice lamp you have here Dave, the burner really dwarfs the amalgam reservoir!

Higher pressure= lower life span though, right?
Max   [Apr 26, 2011 at 08:58 PM]
That's indeed correct - a higher burner temperature is needed to reach the higher sodium pressure, and this causes a faster chemical reaction between sodium and the PCA vessel which, in turn, results in a faster increase of the lamp voltage over time.

Is it possible to keep a HPS lamp working if you were to upgrade the ignitor pulse to a higher voltage? ie BBQ ignitor?
Form109   [Apr 27, 2011 at 11:25 PM]
the ignition voltage should stay much the same,its the opperating voltage that increases.

I heard these lamps can cause early ballast failure as a result of the higher operating voltage. I have only once seen these lamps used in a streetlighting installation (California) but didn't get a picture of it.
