So I played with the motion sensing last night and confirm that it works as advertised! The light includes potentiometers for adjusting the sensitivity of the sensors and the default setting is maximum sensitivity. It registered my movements and turned on from about 30' away.
The status LED is a nice touch, then you know if it is on auto or not with a relatively quick glance. During daylight, the LED with flash blue. After dark, when the auto mode would have the light turn on when motion is detected, the LED changes to flashing green. Green also corresponds to their "battery status" feature which means system voltage is greater than 11.5V. It claims that this LED would change to red if system voltage is below 11.5V. While that sounds great, 11.5V is too low to be very useful for monitoring system status. Even the dummy lights on the stock voltage meter are more useful than that. Too bad they didn't do something like a red/yellow/green where yellow could be something like between 11.5V and 12V.
It is nice that it came with an 1141 LED bulb; however, the light I replaced also used an 1141 that I had already swapped the incandescent out for a bulb-style LED.
Because my existing bulb-style LED had more LEDs on it than the one provided, and based on a purely subjective brightness comparison test between the two, I stuck with my original LED and I'm keeping the one provided as a back up. The one they provided seemed interesting because all the LEDs were mounted flat and pointed in the same direction and you could aim it. But I went with more light all-around with the bulb.
