This LED floor lamp, with one high intensity 5W LED bulb, allows you to adjust the breadth, and therefore the intensity, of the light beam. Using its unique pull shade, the beam can be adjusted from width of 3" to 33" at a distance of 12". As the light beam reduces in width, the light intensity increases.
This lamp is 65 inches tall and has an adjustable gooseneck for aiming the light wherever you need it.
