Small closets can be horrible. Especially if you need to find something in them. Usually home designers don’t install lights, and if they do, they don’t provide full illumination of the space, usually only the tops of hangers.
The Luminook uses lasers to determine a door is open, and then illumines throughout the space, giving full view of the items within, which is great in multi-shelved closets.
Their Kickstarter is already funded, and still running. You can back it by going Here!
