Question about lighting

Hey guy, so i have a question concerning some of the 100 watt hps bulbs, some of them say mogul base and other say medium or standard household base, my question is can the household one be plugged into a regular socket or do you still need that balast for em? Thanks...

here is the page I was lookin at

If it's a med base it should work in a standard socket.

but do I still need a ballast to convert the power or does it run off of 120v? I don't want a fire hazard!

nope. thats the point of the med base no ballast.

cheers thx

You do realize that page is MH and not HPS.
