Can the HPI-T PLUS HOR actually run without an ignitor? « on: August 17, 2026, 05:31:49 AM » Author: RyanHID
I have been wondering for a while and haven't got a stable answer, some people said yes, some people said no, and i've heard it could run on HPL / BHL ballast?

Yes, we have Philips HPI in our paint shop, they’re all running on Philips mercury ballasts, but certainly do need an ignitor to start them.

When brand new, it can start without ignitor, but as it ages, it would have harder starting, so a 750V parallel ignitor is needed.

I only working with the international date format (dd.mm.yyyy).

Ignitor is a must as the lamp ages. But yes they will strike on 220V mains via a simple reactor.
