Upon receipt, the box is disconcerting in terms of its lightness and small size. It seems tiny for accommodating 200 Christmas lights. But then, standard low voltage Christmas lights tend to have HUGE transformers and long strings of power supply lead, which are not needed here. The lights are well-spaced and provide a good length of lighting. These come with one, small, solar panel charger mounted on a spike. It takes a long time to charge them and the panel doesn't seem to be especially effective. It takes many, many hours of sunlight (in short supply in the Winter!) to charge these up enough to run them for even 2 hours, during which the brightness of the light fades noticeably.
A nice idea but, on a set of 200 lights, the reality is dim and short-lived lighting. Looking at the other reviews (there are loads of positives for smaller sets from this manufacturer), I'd still try a 50 light chain of the same type, however in my experience this one is a nice idea but not great in reality.
