I have a new outdoor floodlight that works in test mode. Adjusting the range works. It turns on when you walk in front of it. But as soon as I switch it to 1 minute, 5 minutes, or 10 minutes... the sensor doesn't work at all. The red light is flashing so I know it's on.
I have tried in bright conditions and in very dark conditions but it doesn't work. I tried in auto mode and manual mode but nothing. The thing is it works in test mode which lasts for 5-10 seconds so I know it's working. What else could I try before returning it?
