Yes, and, actually *all* electric lights (except certain
one-color arc lights) give off much more heat than light. 
But fluoresecents and MHs are roughly 5 times more
efficient than incandescents, including halogens, which
give off aobut 94-97% of thier energy as heat.  They are
great heaters, extremely inefficient lights -- which is a
shame because they are so cheap.
