Good job, BeanAnimal!
I was taking a break from re-wiring my hood this morning and was very alarmed when I read the first two posts. I was even more shocked that nobody shouted immediately, "NO, Don't It! You'll Kill Yourself!"
You just may have saved an eyeball, a few lives from fiery death, or the loss of all her possessions.
I hope your warning does not go un-noticed to other readers who may just want to screw in an MH on a home socket. I guess that's why they are made w/ large sockets, make it harder to locate a med-base mH and by then hopefully the retailer can figure out the impending catastrophe and educate the buyer.
lilleahseafreak, BeanAnimal did you real favor.
That was pretty dang scary.
Unless you find a high-quality, well-known product at a super good price, its a high-risk adventure to purchase a ballast system from an unknown source & manufacturer, age and deterioration of the ballast parts.
For under $60, you can get a brand new ballast kit direct from a reputable manufacturer, and with warranty.
Hamilton 175 unassembled mag ballast kit
REPLACEMENT METAL HALIDE 175 WATT UNASSEMBLED BALLAST
Includes transformer & capacitor ONLY. Use with 175 watt Metal Halide bulb.
Price: $59.95
But I think a 175 is overkill for 20gal, unless you have 3 tiers of eggcrate to growout a few dozen sps frags.
Good luck.

I think you need to visit your LFS and get a primer on the different types of lighting and how they work. You also need to do some google searching on how HID lamps work. Metal Halide, Mercury Vapor etc.
From what I gether reading your posts, you may want to stay away from this kind of project until you learn A LOT more about HID lamps, Fluorescent lamps, ballasts, and electricity. I am not being a smartass, but you are worse than clueless with regards to this subject (don't worry we are all "worse than clueless" with regards to many things).
The problem here is that there is great potential for serious inury or harm due to electrocution or fire. Your posts show tht you do not understand the theory of operation and therefore don't understand the risks involved or the steps needed to ensure your safety. This thread is a start to your learning, but you really need to get some hands on (thus the recomendation to visit the LFS). I am sure with a bit of research you will have new questions and new answers. In a short time, you should have enough information to undertake this project safely.
You may want to give the guys at hellolights or reefgeek (to name a few) a call and they will be able to shed a lot of light on your questions and offer ideas on the parts you will need to make this work safely.
