First, the power supply has a permanently illuminated green LED for some unknown reason. In addition, it whimpers when the lamp is turned off or the light is dimmed. Have the NT replaced by an alternative unlit 12V power supply - now whimpers nothing.
Secondly, the switch-touch button is switched off the lamp emits quite badly in the dark. Have about stuck a piece of self-adhesive metal foil. Thus, the standby lighting stands on the bedside table is no longer in the eye and the touch functionality remains the same.
Actually, I wanted only awarded 4 stars due to the above points. After troubleshooting, however, outweighs my enthusiasm for the smart multifunctional lamp and I round to smooth 5 stars on.
(PS My thanks also to the reviewers for the tip, pull the transport protection film from the control panel - so accurately, snugly and virtually invisible - expensive smartphone screen protectors are so old hat against ;-)
