hey.. just wanted to give you my opinion. there is a few homemade lights knocking around,with weezard's being my favorite.... you can find all information
under a tread called "led ohoy" only a handful or less of the commercially sold led panels,seem to work well(wex150,spectra,ixis,magnum?) and all of these
are expensive but if you have electrical confidence you should be able to(or get someone to help you) make your own lights in style with weezards.
by the way i have NEVER heard of one of those ufo's actually being able to flower any serious bud.
led are not cheap if you are looking for cheap,and to run cool maybe cfl is for you.

good luck
