[QUOTE="ampedup, post: 527535, member: 35088"] Thanks for the reply. It gets louder in volume when the brightness increases. I'm assuming it's down to the adapter having to work harder or under stress at full brightness. I was thinking it was probably a quality control issue. Distancing the lamp from the mains more to double check, the sound is definitely from the mains adapter that's plugged into the mains socket. A search online gives me different results when it comes to noises from mains power supplies, often relating a 'still safe' adapter to a high pitched sound (relating to coils or magnetic sheets), but this one is low in pitch. I should mention that the power supply isn't a charger, the lamp is wired only and not portable. [/QUOTE]
