Lines are my current favourite Nanoleafs, they are controlled using WiFi making them more stable than the Essentials range which use Bluetooth or Thread seemingly varied depending on wind direction! I particularly like the split colour aspect of each line and how the light is indirect and diffuses against the mounting surface. This seems to really accentuate the layout chosen and has a much bigger impact than conventional Shapes. One drawback is that all the mounting hubs have the adhesive already stuck on and there are no spares. Whilst you probably won't use all the hubs and so can replace one if there is an issue or you make a layout mistake, you can't do that with the cable inlet hub so be careful!
