I needed a light in a few of my work shops cabinets. I was able to mount this easily inside and since its motion activated i have light only when i open the door. I added the hooks to the other one and placed that above my work bench so at night i dont have to turn on the light when i walk over to the bench to grab a tool it will auto come on and wallah. I am very pleased with these the real question will be how long will they last as 3 tripple A batteries is not much battery life. Time will only tell. I will update this post if anything changes. Till than have a great day.
