This doesn't work for us at all. The light goes on all the time. As in after 5-10 seconds of being off it turns on, and then does that repeatedly. So not useful at all.

This bulb solved my dark garage problem. After trying several other brands that either were not bright enough or had inferior range, this bulb is the perfect solution. The response time is immediate and is activated from any point within the garage. It is even activated by opening the interior door before I even step into the garage.

Very sensitive, but needs longer delay before turning off… picks up motion thru walls and doors, and only stays on for approx 15-20 seconds after no movement detected. If quick is near by within 8-10 feet, light comes on even if not illuminating area where motion is detected. You almost have a strobe light with cycle time as to the lamp is very sentimental come on and quick to turn off. 60 seconds to shut off would be more useful, but 15-20 seconds, if you enter a large room say a master bedroom, by the time you reach the opposite side of the room, the entry light would already be off. There are no setting adjustments for time or sensitivity.

Some time both lights don't go on

These things hit right on the money. Sometimes they go off when there is a vibration of significance but otherwise they are 100% reliable.
