I use these a lot when I'm out working on my cars. I restore cars and sometimes am up working late at night. I can just put a couple of these on the bumpers and my tool box and it helps to illuminate more so when my wife walks out to see me or a friend walks up the path they don't end up tripping over something. They put off a decent amount of light that is more for showing an objects presence than say, using it to see objects with like a flashlight. Overall I am very pleased with this item.
