how exactly does this work? is it battery operated or does it have to be electrically installed?

It is electrically installed. If you are replacing an existing light it is probably just a matter of untwisting 3 colored wires and twisting the new ones back and mounting. Flip the circuit breaker 1st to protect yourself.

It's installed like any other light fixture - attached to the home's wiring.

I had to return the light because it needs an electrician to install even though my husband is an electrician. It would be great for a big remodeling project or new build and it was beautiful. I was bummed to have to return it.

It is not battery operated. It has an AC adapter for the power source. Now you could use it in your car with a converter and set the radius.

Neither electric or battery operated. You just use the force of your hand to rub it back & forth over your heel with marvelous results!

It's electric and plugs into a 110v outlet. You will most likely need an extension cord since the one on the motor is only a couple of feet max. Not a major issue though. So far it works well.

Does not use batteries, you have to have it plugged into the electric outlet all the time.

It is battery operated, it requires four AA batteries, but arrives with a full set already installed, so you can put it to work immediately!

It works without batteries. When you pierce the wire insulation, thats hiw it gets it's power. The alligator clamp opens and you place it on metal for ground. That nakes the connection for a circuut wich activates the light.

It has to be plugged in to work. No batteries, but has an on/off button. I have it sitting on top of some files in the lower part of my desk as it doesn't really radiate a lot of heat unless it's close to you. I like it though.

This unit must be installed onto a junction box and connected to line voltage power. It does not use batteries.

This is battery operated. Nothing to do with a doorbell. The outside of the door looks like any other peep hole. On the inside you push a button to see who is there. I love it.

It needs to be plugged into the wall socket at all times. No battery operated function.
