This is the floor lamp with a widening/narrowing light beam and a built-in side table. Simply turning the shade adjusts the light beam to 711 different diameters between 3" and 31". At maximum zoom, the 3"-diameter beam produces more than 10,000 LUX (2 1/2X brighter than a typical lamp), ideal for illuminating fine details of crafts. When adjusted to the 31" beam, the lamp provides optimal light for reading or ambient illumination. The lamp also helps reduce eyestrain with an adjustable color temperature up to 5,700 Kelvin that simulates natural daylight. Its glass tabletop conveniently holds books, beverages, remotes, and reading materials close at hand. The light turns on/off with a tap of your foot at the base. AC plug. 54" H x 12" Diameter (base).
