Initially with charged batteries, the light output was logically well. The solar cells and especially now in the autumn and winter and on the west and north sides have enough power to charge the battery properly. On sunny days, the lights are not more than 1-2 hours. If there are already around 17:00 clock is dark, this is simply insufficient. If until 22:00 clock it is bright in the summer, the lights are naturally longer, but nobody notices it! Therefore, I can only advise. Otherwise look OK, delivery also good, but what is the use lamps which hardly light up.
