40-Inch Height Desk Lamp

The LitONES F650-B-LitUS is a 15-watt LED desk lamp that extends from 14 inches to 40 inches, reaching above dual or triple monitor setups and standing desks. Its square painted finish and 2.86 lb base keep it stable on a 10.0 by 8.0 inch footprint. The 50 selectable light modes cover a colour-temperature range of 4,000 to 6,000 kelvin for varied tasks.

Edge-Lit Optical Panel Build

A four-layer edge-lit soft panel diffuses light at the source, producing a broad flicker-free field without harsh shadows. The lamp head adjusts smoothly through the full height range, and a tap timer turns the unit off automatically after 45 minutes. The 43.0 inch overall height when extended suits tall workstations that shorter lamps cannot illuminate.

Upgrade From Short Fixed Lamps

This model replaces compact desk lamps that top out below monitor level and leave keyboard areas in shadow. The jump is worth it when your workspace demands overhead coverage for multiple screens, video calls, or detailed drawing, and when a fixed-height or lower-output lamp no longer meets those needs.
