The Solar PIR wall lamp Super Effect is the second best solar lamp that I know. However, the two solar cells to provide four LEDs with power. The motion detector is working properly and turned on the light-emitting diodes in motion brighter. The light is really good to brightly illuminate a walkway, but in the winter months the battery is not fully charged and the whole works then just a few hours. All this packed into a stainless steel housing, for me a good product without wiring. But the Pir wall lamp EFFECT with only one solar cell has only one LED with electricity, functioning much longer and I would prefer this product definitely.
