I wanted to try these cheap battery operated Ikea lights with motion sensor for automatic staircase lighting. They seemed nice but the light was way too harsh. The lens in original light is designed to give you a spot light but I that was not what I wanted. I removed the lens but the shadows were still hard. Then I tried adding a half of a ping pong ball and it started to look what I wanted. It looses some of the luminosity but it’s enough for the staircase. As a bonus the uppermost light also lights up when you go to the bathroom at night.
