Mercury Vapor light morass

Correct me if this isn't the best place for this topic. I recently began to develop a mercury vapor light setup for attracting moths. Currently, I'm plugging into the house using an extension cord because I don't have a generator (yet). I ordered a 160-watt medium (E26) base bulb. Turns out it was a coated bulb. I've gotten okay results with it so far, but the site I consulted advises using clear bulbs.

I now have two 175-watt clear mercury vapor bulbs. I have a medium (E26)-to-mogul (E39) base reducer so that the bulbs can screw into my lamp. I discovered that rig wasn't working because such bulbs require a ballast. Maybe I will have to purchase one and wire it myself. Maybe I have no idea what I'm talking about.

Bottom line: Hopefully some moth enthusiasts here can pass some hardware secrets on, particularly relating to light fixtures. Thanks for any help!

I have purchased lighting systems over the years through BioQuip Products, a nice online source for all things bugs! I purchased both a 175 watt and 250 watt system from them for my portable set-ups, including weather protection for the bulbs. The lights have been reliably lighting for years and replacement bulbs are available. The company is customer service oriented. They are at

I doubt that you will see much, if any, differences in catch between the 2 bulbs.
Perhaps the easiest way for the 175-watt is to buy an entire fixture as sold for home-owners dusk-to dawn lamp:
