Why american ignitors, are specified with specific ballasts? « on: March 29, 2017, 07:38:44 AM » Author: dor123
While european ignitors can be used with all types and wattages ratings of HPS and MH ballasts, american ignitors are specified to specific type and wattage rating of ballast.
Why this is the case?

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

Mainly with HPS, each lamp type and wattage has different arc voltage and different OCV (both are optimized to yield the maximum typical lamp efficacy for the given power level), so need different ignitor triggering voltage.

In Europe, virtually all ballasts are just a series choke, that means the OCV is the mains voltage, so the lamps are adopted to that. Because the voltages are fixed (not dependent on wattage,...), all require the same ignitor triggering voltage (~210V).
