Fureelz is right, packages are cheaper but sometimes the gear you get in it can suck. A lot times, as with most things, its matter of price vs quality. Ebay is a good choice, especially if you dont want use a credit/debit card. There's also htgsupply.com, bghydro.com, and a few other smaller companies, I would say google the lights and shop around if price is a big issue. You could also buy a ballast kit and then the reflector seperate, or build your own reflector if your a do-it-yourselfer, theres a bunch of cooltube and batwing reflector threads on here. Hope that helps. Good luck with your grow show
