The Brilliant Evolution Wireless LED Motion Sensor Light 3 Pack is awesome!  These are a nice bright white light. I like that the  motion sensor automatically turns the light on and then off again after 30 seconds of no activity.  These only work in darkness, conserving battery life, which is great.  These take 3 AA batteries which we have yet to need to change, so they really conserve energy well.  The lights come with adhesive tape or screws to mount with as well. The lights are small, look nicely made, and feel like a quality product.  We used these to light a walkway down our staircase and the light it provides is excellent. I highly recommend these lights!
