The rear LED illuminates the transparency controlled by the PIR/radar sensor at night as needed. Photo Frame option Picture 1 I used 6 \"x 6\" in pure black \"(150x150mm)
There are four AAA batteries in the battery box)I measured a current drain of 88 mA, which resulted in a current of 18 mA through seven series led. If these seven LEDs are connected in parallel with the independent current limiting resistor, the current drawn from the battery will be 126 mA (=18 x 7).
