Useful tips

  • Attach the cable

    Work with the light on its side. Channel the cord through the groove, avoiding twisting. Turn your lamp upright, ensuring the cord remains in place.

  • Set the mood

    Hold the power button down for five seconds to start cycling through the various dimmer settings.

  • Position your lamp

    The LED head moves around three axes so you can position it right where you need it.
