You don't have to wait till after dark to appreciate the beauty of these solar powered stringlights, they have a gorgeous iridescent coating that shines in violets, pinks, greens, & golds, similar to 'chameleon' paint or the colours in oil. The orbs are filled with tiny bright white firefly LEDs, but the colour effect when lit looks magical, full of little bursts of blue, golds, greens etc, & as the orb is 'ribbed', this creates infinity reflections, making it look like there are many more LEDs than there are. The lit length of the lights is 2.7M with a further 2M of cable from the solar panel to the start of the lights, & the orbs themselves are big at around 7.5cm diameter (larger than a tennis ball).
