you could go to your local electrical supply store and tell them you need a light for your driveway area. they will build you one to suit your needs so i'd ask for a 250w which is good for a couple plants or starting 8-10 seedlings.

buying seeds before your equipment is kinda like buying fish before the aquarium...

also, you really should do some reading and learn the terms so you'll know what you're talking about when you get started. you're reading it here anyway so might as well do some advance homework and save us some typing...

here's a good start:
