All functions work with the lamp plugged or on battery.
I put it on my dresser so all it takes is a tap to illuminate the room if I need to find something near my bed or get up to use the washroom.About the actual mechanism of the light; you tap on the bottom of the light and a weight mechanism in the light moves with a satisfying *click* sound and turns on.
You can either have the light turned off by placing the switch in the middle, or chose between a low or high setting for the LED's.
It’s the perfect amount of light and I love that you can charge it.
I bought this for while we have a newborn in our room for a night light (nught feedings and changes) it works great.
Purchased two lights, first one never worked properly, second one worked great for 3 months.
Initial purchase wouldn't work unless plugged in (didn't hold a charge).
It was bought as a gift, so I re-purchased with the intent of returning the original bum unit.
I never actually returned the initial unit, so that's on me.
Second purchase worked great, until last week.
