Hi Olivo 25,
If you have an electromagnetic ballast in your luminaire you need a starter, in mine it was an electronic ballast so there was no starter. The neon in question works without a starter... it won't work in your home. You need to order another neon.
For more detailed technical information, please refer to the datasheet available at the following link:
