Electrician question: grounding a ballast for retrofit light installation

[banditpowdercoat]

I know to scrape. But just dont ever recall the factory ones being scraped at all? just funny. I must have installed/repaired 1000+ fixtures in my career, never noticed about the ballast itself grounding

With my new retrofit fixture I grounded the ballasts. Both the icecap 660 and the advance dimmables had a spot to insert a ground wire.
