I love this harness so much on light bulbs! Instead of turning the porch light off in the morning and on at night, all I have to do is turn the switch on and leave it on. I didn't turn the lights on until late at night so I wasn't expecting them to light up the first night but they did. I love warm white too! I was fed up with another brand and it was super bright white light and it felt like too much for me. I definitely recommend it! I'm not sure about the motion detection aspect, so no review yet.
