Lightbulb Fluorescent bulb → Ballast → Electrical Plug?

Hi!

I'm looking to connect a Circline T9 22W Fluorescent Tube, to 4-pin Sunlight 22W Ballast, then connect the Black (hot) wire to the brass screw and the White (neutral) wire to the silver screw of an electrical plug (15 Amp 125-Volt Double Pole 3-Wire Grounding Plug), then go directly into an outlet.

My question is about the Ground. Is this okay as diagrammed? or must I ground the Ballast case somehow?

I understand that grounding is usually automatic if the light fixture is grounded properly (a metal ballast mounted to a metal light fixture would automatically ground the ballast)

However, if I'm not using a metal light fixture, and not hardwiring this... I am wondering if this freestanding set-up to a wall outlet is safe, or if I need to somehow ground the ballast case?

Thanks so much for your help!

What are you doing with the tube..... hanging it on the wall ?
Most fluorescent tubes need to be located near a grounded metal case/fixture to light correctly.

The supply wiring to the ballast is supposed to be contained within a junction box or approved light fixture.

It will work, but there is possibility of electrocution when that ballast fails as it can short to metal casing. The is the main reason for grounding.

Also, fluorescent light is supposed be on grounded metal for it to work properly, but I did find it works just fine without ground in most cases.

Why even bother with fluorescent light anyway? LED will be much better choice these days.
