I know that is probably an extremely stupid question but Can I get 12V out of a 3.6V battery? I have a faulty LED hula hoop (which currently has rows of LED's, some broken!) and I want to insert a strip of LED's (Like theses ones (which say that they run at 12V)) but the battery I have in there at the moment is a 3.6Volt battery.
Is there anyway to boost the charge to make it work? What voltage do LED's usually run from?
