I have a plan where all the components powering the light sit below the light housing in a standing projetor design. The lamp housing will be on a metal plate. I was wondering if these ballast, transformer, ignitor should also be on a metal plate?
In terms of grounding can I just ground to the metal plate that sits above the ballast?

good idea
You should have the ballast and transformer frames grounded. That way an internal short will blow a fuse instead of giving you a "hot chassis". You could do that by mounting them on a metal plate and then grounding the plate. Or just run a ground wire to each one's mounting hardware.
I have not seen anything you could connect to ground on an ignitor, but if it had a metal jacket, then you could ground that too.
Make sure you are not overheating the ballast parts by exposure to light or heat without cooling air flow.

Sorry , could you clarify this for me please. So if i use a metal plate and the ballast, transformer sit on it, I could take 2 wires.
Connect one end of each of these 2 wires to the metal plate and the other end of each of these wires to the units metal frame?
And the fuse goes where?
And what if I dont want to use a metal plate to mount the ballast , transformer on.
power circuit
In the US, the black wire in the power cord is the hot side of the power. It will be around 120 volts AC. The white wire is the neutral side of the power. It will be close to 0 volts, relative to the earth. The green wire is an earth ground connection.
Your power cord will have three wires. Brazil has 127 VAC in some areas, and 220 VAC in others, but both will be at 60 Hertz.
***Be very careful***, because you may have a socket that is wired incorrectly, your country may use a different color-coding, you may have 220 VAC, or you may have a power cord that does not have colored insulation on each wire! You have to find out which wire is hot and which voltage it carries before wiring anything.
The hot wire connects to the switch. The other pin of the switch connects to the fuse. The other pin of the fuse connects to anything you want to supply with power. These would be things like your ballast, an AC fan, a power supply for DC fans or your LCD, etc. The neutral wire is connected to the other pin of all of those items to complete the circuit. (I use two switches, so I can leave the fan running for a while after I turn off the lamp and LCD.)
The ground wire should be connected to the metal box that surrounds all the electrical parts. If all the parts are not inside a metal box, then the ground wire should be connected to the individual metal boxes around parts. For example, to the ballast frame and the power supply enclosure. If you mount all of those parts on a piece of metal using metal screws or bolts, then you can connect the ground wire to anything in that circuit: The metal bar or a mounting bolt.
If this is confusing, then you should take the parts and the ballast wiring diagram to an electrician. He can wire it safely and should not charge you much, since it will only take 15 minutes.
