I am wanting to put a LED light under a deck lid. I want a stand alone battery unit that will turn off by itself after a given time.(Don't want to hard wire anything) I have found some that are motion activated that will stay on 15-20 seconds once no motion is detected.

Does any one know of any that are on a timer? Once turned on, it will turn off after a certain amount of time? What are other options?
