This light is not ul certified. If you're looking for a light that won't make you look undead, spend the extra couple dollars and skip this one.
The motion sensor works fine, the light stays on for only about 10 seconds. Mounting bracket is garbage grade aluminum and the screws are hilariously short. The lights boast an 18-month warranty but amazon is unable to locate contact info for seller.
Only lasted about 4 months. They stay on 24/7 unless you turn off the breaker. After 1 year, light just stays on.
