I have one and it acts the same way. The only difference I know of is that in daylight mode, when it's actually daylight, all 4 of the underside LEDs light up. In senso mode, only 2 of the LEDs light up regardless of conditions.

At night both settings switch to night mode, and light up just 2 of the underside LEDs.

Have a Phillips SafeRide light now, but it also has it's problems.

Some notes on a comparo I wrote here. http://www.candlepowerforums.com/vb/...mp-M-IQ-CYO-RT
