The Solar PIR Wall Light Effect is the best solar light that I know. The relatively large solar cell is sufficient to let the light-emitting diode in the dark winter months glow all night. The motion detector works properly and switched the light-emitting diode in motion brighter. The light ranges from really good to illuminate the walkway and you can really see everything. All this packed into a stainless steel housing, for me until now the best product without wiring.
