Arc Desk Lamp is a wireless charging table lamp, compatible with any smartphone with built-in charging capability or phones with wireless charging cases. Its modern technology can help improve your sleep with its sleep mode. Over-exposure to white light before bed can dramatically affect your sleep pattern, with the night function you can switch to a warmer light temperature at the click of a button the same as on the latest smartphone. If you are guilty of leaving lights on and forgetting to switch them off, set the timer option which will automatically switch off the light after 40 minutes. It is super-efficient and only uses 11W of energy, in simple terms, it could cost as little as 20p to have it running for a whole month.
