I purchased two sets for my deck. They were easy to install and we chose the color mode. We didn't  want bright lights on our deck, we wanted just enough for a warm atmosphere so not to take away from our fireplace or seeing the stars above without a white glare. They all are solar and within a few hours of sunshine was enough for a full night ti.e charge. I would recommend this product if your looking for a soft light to enhance  your deck railings
