The brightness sensor is good, on relatively early (late afternoon) and off doing it until the late morning.
To notice would also be that the sensor also adjusts the brightness to the lighting conditions. The darker it is, the brighter the light is (felt in 10% increments) -
The burn time so here is approximately 18 hours (winter months). Since the power consumption is not even 1 Watt .... seis drum :)
18 hours a day in winter and will probably at 8 hours (22h - 6am) are in the summer.
Arithmetic game 366 days / 2 = 183 days x 18 hours X 0,85Watt = 2800 watts / year (2,8KWH) - ie 60 cents / year.
183 days x 8 hours x 0,85Watt = 1250Watt / year (1,25kwh) = 30 cents / year
Rounds are all generously to the lighting so that costs 1 euro per year.
Even if they would light around the clock, it would 7,5KWH and at about 25 cents per KWH only 1.8 per year.
Strong buy recommendation. :)
