No they wont,way too much heat,they will cook your plants crispy overnight plus the light spectrum is all wrong.
Really you do need to do some real research,just asking questions blindly will get you nowhere.
Go to the grow faq here on this site & read the whole thing,every last folder in the faq.
GROWFAQ
Then go the "journal forum" & read your ass off for a few days,this will get you a real understanding on what your in for & what you can expect as far as what kind of room & light systems you'll need to grow productive,smokable & top quality weed.
After that then go here to find the lights you'll need.

Im not trying to be a dick but you really need to spend some time doing atleast the bare minimum of research on growing indoors,if you had you'd know that halogen lights are out of the question within your first 10 minutes of reading.
