Yup kinda sucks, pretty good price on that package.

But you have to look at it this way... .5 grams per watt and up, so 200 grams with that light is very attainable. Plus you cut about a month off from your harvest cycles with hps vs. cfls and fluoros.

Add another $100 or so for ventilation (the more DIY the cheaper!) and you make back your invest and much more in one grow. There are DIY cooltube and carbon filter instructions on this site. Also google DIY Stanley Blower conversion (I think icmag has a thread on that).
