I've heard you'll need about 20,000 lumens total in your growroom. This can be done with one HPS bulb, or many CFL bulbs.

A CFL bulb (Compact fluorescent light) is about the same size as a regular lightbulb, but is a twisted up tube instead of just a round bulb.
When buying CFL bulbs, be careful, always try to look for lumens, since they show "real wattage" and "incandescent equivalent wattage", which can be confusing.

Home Depot has a pack of 4 bright bulbs for $12 canadian, i'm sure Canadian Tire does too but i didnt look.

Here's a link with all the stuff about CFL, most importantly a picture of what the bulbs look like:
