To be honest having experienced the old D&D lamp I didn't expect the D&D lamp and sensor to be like this are reliable, but after 3 months it works great. It's hard to see how much energy just a lightbulb saves, but it certainly saves my "energy" switching on and off, and definitely electricity, because with regular lightbulbs, I often forgot to turn them off and when I it's been a few days away from home, don't worry, the thing does its job, respect. Updated October 30, 2021; 6 months later, the same light bulb will do.
