light bulbs

this place got really good deals on light bulbs and accessories.
i found a 100w hps bulb with a medium based(E26)base and correct me if im wrong but it can be used in regular 120v light fixtures good for new growers and they only 15$ a bulb.

You will still need a ballast....I had a few of these a few years back, I paid 10$ at a hardware store. They wont work without a ballast.
