It's durable weatherproof design allows it to be used anywhere. Great to light anything from pathways, closets, stairways, patios, bedrooms, gazebos, and anything else you can think of!

It automatically turns on whenever it detects motion, and automatically deactivates if motion is not detected for 30 seconds or 10 minutes, depending on the setting.
