I was told the full spectum light if you put it in an overhead fixture would be to far to do any good.. Some one on the boards here told me if I remember correct no more than 3 feet. at the bird store that specializes in selling birds only here, they told me no more than 3 feet.. I have a clip on I clip it to the top of her cage when her cage door is closed so she cant get access to it by crawling ontop of her play area...I also purchased these plastic things that stick to ur wall, it has a little clasp for the cord to fit in, so the cord is kept close to the wall and not dangling down the back of the cage..Another idea i recieved from a poster here...I to cannot have my birdie outside as its way to hot TN has been in the 100s with heat indexes up to 118 last week..
