LED sensor light bar

Fast delivery to Mo from RF-4 days, Courier IML to the door. The lamp itself is made well, the body is solid, the sensor in the dark is triggered with 3,6 m exactly (the lamp at 80 cm height was installed), I did not check further. For this size of lighting is normal. Precharged the built-in battery in 30 minutes, worked after charging more than an hour for sure-the flight is normal. I bought to make a backlight under the sink, but here the lamp works at greater darkness, what we would like. I think how to provide her work in the twilight of seicha, if anyone knows, then tell me, please. Product and seller recommend.
