Props, a tar ballast can be a pulse, magnetic, or HQI so the above statment dosen't apply to this.

a USHIO is a europen bulbs which has been turned into a probe start so yes any of the above ballasts will fire it.

the only way you will have a problem is if you try using a pulse start bulb with a probe start ballast. the other way is fine.
