MH- transformer and capacitor,
HPS-transformer, capacitor and igniter,
You would also need a chassis, connecters, wire etc. as well as a fixture(socket and reflector ) to have a complete unit.
Ballast kits are available, and may be the easiest way if you feel confident in your electrical skills. If you are in any doubt best use a prewired ballast though, it's possible to screw them up, and that is a fire hazard.

30 amps. 40 amps for a cushion. Now at 40 amps, might better off running 2 lines/breakers to balance the load.

thanks for that..
heres another question.
do i need a ballast for a 100 watt HPS? or can i just stick it into a normal light fixture?

Put the screwdriver down and no one gets hurt!

NO! HPS/MH/Floro need more then just the straight mains to the bulb terminals.

*you* need to buy a pre-made/wired lamp. (save a life, most likely yours)

I am lucky enough to have the breaker room in my grow room, anyhow, how do i wire a few 15 ( or 20 amp, whichever is better, atleast want to run 1200 watts in lights some day ) Breakers, How do i go about this not shocking myself..

Any reading material you can point me to?

Buy the following:

1 25foot roll of romex 12-2awg wire
2 or 3 (your choice) 20 amp outlets back feed design
2 or 3 Outlet boxes (Get the Heavy duty HPDE plastic one, there more fire resistant)
2 or 3 20 Amp Breakers (MAke sure to get the same brand as your main power supply)


Directions:

1. Tap in where you want you outlets to go, and install the Recep Boxes.
2. Cut out the appropiate length of wire you need for each outlet PLUS like 5 or so feet.
3. Turn off Main Breaker Dissconect.
4. Test adjacent outlets arounf to make sure there is no power coming from main.
5. Knock out a Knock out, or go through a already open one.
6. Feed wire into main box.
7. Split wire into its three wires and strip back to where the wire goes into box.
8. Leave the wire hanging
9. Run the wire over, under, through whatever to your recep box and feed into it.
10. connect wire to your recep and install recep into its outlet box.
11.Connect Main side wires to you new breaker. and to the appropiate bus bars.
12. carefully connect you breaker to your main panel.
13. Pull all extra wire taught, and secure with electrical wire staples every 4 feet or less
14. Knock out new spaces in the main box panel for the new breakers.
15.Turn back on main breakers.
16. TEST new outlet(s) with a outlet tester.

Tidy up, and put a cover on the outlets.

also a few of these may be done in a slightly different order like pull the wire taught, then staple then sut excess, the strip then attach to new breaker, then connect breaker.

You will figure out your appropiate strategy.

Thank you for the detailed post - ill give you an update here soon when i do it, and if i have any questions, mind if i pm?

Alright, I have a power strip(15A 125V 60Hz 1875w). Can I connect a Light timer(125V 60Hz 15A 1875w) to a 2 split extension cord(125v, says that on both sides of outlet) <does that mean it equals 250v? Connected to that I have a "screw in bulb thing" that you can plug into the splitter ext. cord and its connected to a "Y" splitter bulb thing(it can hold 250v each) and could I put 2- 26w bulbs in it? (total of 4- 26w bulbs). Does that make sense?? I can't really explain it...I will try to get pics
