I’ve had very bad luck with Mr. Beams Remote Control Spotlights.
I purchased a 4-pack from woot quite some time ago and they all failed (some sooner than others). Typically, they would fail to respond to the remote control button(s) even though the batteries were tested and found to be in excellent condition. Other lights would come “ON” and not go off ever until I took them apart and removed the 3 D-cell batteries. I eventually called Mr. Beams and they sent me a couple of replacement lights and they also failed in a short amount of time.
