Running HPI-T lamps on CWA ballasts? « on: February 21, 2021, 09:06:00 PM » Author: WorldwideHIDCollectorUSA
After knowing that both Philips HPI-T and some high pressure sodium retrofit lamps have neon argon penning mixtures in their arc tubes, I know that penning high pressure sodium retrofit lamps for mercury vapor ballasts can damage CWA ballasts. I wonder if using a Philips HPI-T lamp on a CWA ballast will also cause ballast damage too?

The Philips HPI-T isn't intended to be run on CWA ballast.

I don't think you may ever damage the CWA ballast by any lamp. But you may damage a lamp by the CWA ballast, if ir is not designed for it and runs e.g. into a tyermal runaway mode. Maybe if the ballast is already dying with weak insulation, a lamp with internal ignitor generating elevated voltage spikes may "finish up" the ballast faster, but that ballast was already dying in the first place, so to me that does not count as a "lamp damaging the ballast" case.
