Nanoleaf rolled out its new Lines Skins Tuesday. They attach to the Nanoleaf Lines lights to change the color of their white plastic bars. That can help them blend in nicely with a room’s design and decor.

Nanoleaf rolled out the latest in its catalog of modular, HomeKit-compatible LED smart-light panels. Following a parade of shaped-product releases — triangles, squares, hexagons — you can now buy Nanoleaf Lines for $200 and use them to make all sorts of lighted shapes. And you can sync them to action on a screen or to music.

It’s not too late to get ready to give trick-or-treaters a fright on Halloween night. Philips Hue offers 20% discounts on various HomeKit-compatible multicolor lighting packages. Think what you could do with a well-placed Grim Reaper and a motion-activated spotlight, for example. And maybe a blood-red lightstrip along the hedge. Throw in a few fiery jack-o’-lanterns, and you’re good to go.
