Ours is an unlit tree. I didn't want the lights because eventually they will begin to go out. We bought ours at a local Christmas tree farm that also had "fake" trees too. My mother has replaced her lit one twice in the time we've had ours (her lights were going out).
We also have the option of going with white or colored lights. This year I bought the LCD snowflake lights--adorable!
Forgot to add--try QVC, they usually have a bunch of trees.
