Yes, certain lamp models do have replaceable blasts.
This white ballast works with the VF01, VF02 and VF03 if your lamp has a white ballast that's not soldered in and it explicitly says "Replaceable Ballast" on the base of the lamp (the underside).
This black ballast works with the older versions of the VF02, VF03, VD03 and if your lamp currently has a black ballast.
If you have any questions about what ballast your lamp takes and if it's replaceable, please don't hesitate to call us at 1-800-786-6850. We'd be happy to help!
