"The Holmes LED Magnifier Floor Lamp w/Smart Switch brings a stylish and versatile option for work inspection, hobbies, and crafts. The black metal disc-shaped shade contains a 4"" diameter strong 3x magnifier surrounded by an efficient integrated 8W LED light. With three color temperature settings and three dimming settings, the lamp meets the needs of any working environment. The round shade is attached to a long thin steel tube that can be twisted and readjusted, allowing you to redirect the light wherever it's needed. Depending on how the arm is positioned, the lamp height ranges from 39"" to 56.5"". Supporting the magnifying light is a heavy and stable round base in black finish that matches the light shade. The lamp is operated by a touch smart switch located on the shade to easily adjust the lighting levels and color temperature at the touch of a finger."
