Adding a ceiling fan to circuit of light fixtures
You can do this because the standard fans draw only ~&lt; 1 A of current. This is an easy way to install a fan but of course the lights must be on for the fan to be powered.

You could switch the fan off and change speeds with a remote controller. Receiver in the fan shroud and battery powered remote controller.

If you don't want to bother with a remote, you could control the fan with pull chain switch. I have had some trouble with the remote that came with the new Hunter fans. Or the problem may be with the fan itself. It won't run on high.
