If you hate dark closets and want to light them automatically when opened,
this is a less than ten dollar solution, assuming you have a source of power available. Even if not, the nine foot cord gives a fair amount of flexibility about where to add an outlet if batteries just won't do. Of course a single bulb may not provide perfect lighting depending on your setup, but as one reviewer noted, you can use an outlet to plug adapter to allow for more options (he used a light rope) while retaining the switch functionality. All in all, while it's not pretty, it's cheap, quick, highly rated, and removable if you're renting.
