Smart RGB Strip

Ten or twenty metres of it — a shelf run, a desk, or the whole length of a wall.

5050 RGB LEDs on a cuttable, self-adhesive strip. Runs on 12 V from its own adapter and plugs into a US outlet, rather than drawing from USB.

Colour, brightness and effects come from the 44-key remote, or from the phone app over Bluetooth.

10 m (32.8 ft) or 20 m (65.6 ft). The 20 m is waterproof.
