40-Inch Adjustable Desk Lamp

This 15W LED desk lamp extends from 14 to 40 inches to cover large work surfaces including multi-monitor setups. The LitONES F650-B-LitUS suits home-office users, video-call participants and anyone needing broad, flicker-free illumination for long sessions.

50 Light Modes With Memory

The lamp offers 50 distinct brightness and colour-temperature combinations spanning 4000–5800 K, plus an extra feature that pushes output to 5500–6000 K. A memory function recalls your last setting so the same light appears each time you switch on.

Simple Plug-In Setup

The unit stands on a painted square base measuring 10.0 by 8.0 inches and weighs 2.86 lb, so it stays stable at full height without clamping. The only common issue is ensuring the power cord reaches an outlet when the lamp is raised to 40 inches.
